• Nervous system and sensory processing — Over-responsiveness to light, noise, screens, crowds, and emotional pressure, with consequent agitation or collapse (see Mind; Head; Sleep). [Kent], [Morrison]
• Head (pressure headaches, migraine patterns) — Head pain from stimulation, overthinking, or “pressure builds then releases”, often with eye strain (see Head; Eyes; Generalities). [Boger], [Clinical]
• Sleep regulation — Difficulty switching off, vivid dreams, and unrefreshing sleep from mental overactivity; sleep changes are a key confirmation (see Sleep; Dreams). [Kent], [Morrison]
• Stomach and appetite rhythm — Alternation of restraint and indulgence, nausea from overstimulation, or appetite changes linked to guilt and control (see Stomach; Food and Drink). [Clinical], [Sankaran]
• Liver and detox-sensitivity (functional) — Sensitivity after alcohol, rich food, or late nights, with headaches and irritability, suggesting a “temperance” axis when clearly present (see Head; Stomach; Generalities). [Clarke], [Clinical]
• Skin reactivity — Stress itching, flushing, or eruptions that mirror nervous arousal and improve as the system quietens (see Skin; Perspiration). [Kent], [Clinical]
• Heart-autonomic axis — Palpitations, trembling, and sweat with sensory overload or emotional pressure (see Heart; Perspiration; Generalities). [Kent], [Morrison]
• Throat and voice restraint — Tightness when speaking truth, or a controlled voice that breaks under pressure (see Throat; Mind). [Clinical], [Sankaran]
• Eyes and visual fatigue — Eye strain from screens and bright light, with headache and irritability, improved by rest and darkness (see Eyes; Head). [Clinical], [Boger]
• General constitutional balance — A striving for inner stillness, purity, and order, with distress when life becomes chaotic, noisy, or excessive (see Generalities; Mind). [Scholten], [Sankaran]

• Better for quiet and low stimulation (general) — Relief when the nervous system is not bombarded; symptoms settle across mind, head, and sleep. [Kent], [Morrison]
• Better for dim light or closing the eyes (eyes/head) — Eases sensory overload headaches and irritability from screens. [Clinical], [Boger]
• Better for fresh air and gentle, unhurried walking (general) — Regulates inner tension without exhausting; often improves headache pressure. [Boger], [Clinical]
• Better for warm, simple meals (stomach) — Steadies reactivity after excess; reduces nausea and irritability in sensitive patients. [Clarke], [Clinical]
• Better for regular routine and early bedtime (sleep/general) — The organism stabilises when rhythm is protected, confirming the sleep axis. [Kent], [Boger]
• Better for hydration and soothing warm drinks (throat/stomach) — Calms dryness and the “wired stomach” in overstimulated states. [Clinical]
• Better for solitude or being unobserved (mind) — Relief when social pressure is removed; thoughts become quieter. [Kent], [Clinical]
• Better after confession, apology, or “clearing the slate” (mind) — When guilt and self-judgement ease, sleep and appetite often normalise. [Clinical], [Sankaran]
• Better for gentle massage or pressure on temples/neck (head/back) — Releases held tension from sensory strain. [Clinical]
• Better after perspiration from mild exertion (general) — A “release” that can reduce pressure and calm the mind when not exhausting. [Boger], [Clinical]
• Better for cold applications to head in some migraines (head) — If heat and throbbing dominate, coolness can soothe; confirm individually. [Boger], [Clinical]
• Better when abstaining from alcohol and stimulants (general) — The system becomes steadier and less reactive; a strong confirmatory modality when consistent. [Clarke], [Clinical]

• Worse for noise, crowds, and multiple inputs (general) — Sensory overload triggers irritability, palpitations, headache, and insomnia. [Kent], [Morrison]
• Worse for bright light, glare, and screens (eyes/head) — Eye strain builds into headache and mental agitation. [Clinical], [Boger]
• Worse for late nights and irregular sleep (sleep/general) — Next-day reactivity increases; cravings and mood swings may worsen. [Kent], [Boger]
• Worse after alcohol or rich food (head/stomach) — Head pressure, nausea, and remorseful irritability; confirm if repeatable. [Clarke], [Clinical]
• Worse from emotional pressure to perform or “be perfect” (mind) — Tightens the whole system, with throat and chest tension and sleeplessness. [Sankaran], [Clinical]
• Worse from arguments and harsh confrontation (mind) — The controlled exterior cracks; trembling, tears, or shutdown may follow. [Kent], [Clinical]
• Worse in the evening and at bedtime (sleep) — Thoughts race, conscience pricks, and the day’s stimulation replays. [Kent], [Boger]
• Worse from strong smells and busy environments (stomach/head) — Nausea and head pressure from overstimulation. [Clinical]
• Worse from heat and stuffy rooms (general) — Increased irritability and restlessness; may worsen headaches in some cases. [Boger], [Clinical]
• Worse from stimulants (coffee, energy drinks) (heart/sleep) — Palpitations and insomnia in sensitive individuals. [Kent], [Morrison]
• Worse from suppression and “white-knuckling” impulses (mind) — The more control is forced, the more pressure builds, then breaks through as bingeing or sudden symptoms. [Sankaran], [Clinical]
• Worse from self-reproach and guilt (mind/sleep) — A moral tension that disturbs sleep and digestion; improves when the mind quietens. [Kent], [Clinical]

Amethystus frequently suggests a mind that is over-awake, impressionable, and inwardly busy, even when the patient appears calm and restrained outwardly. [Scholten], [Sankaran] There is often an earnest striving for clarity and self-control, with distress when impulses, cravings, or emotional waves threaten that control; the patient may describe themselves as “trying to be better” yet feeling internally pressured. [Clinical], [Sankaran] Sensory stimulation is not merely annoying but destabilising: noise, crowds, screens, and constant messaging can produce irritability, trembling, palpitations, or a need to withdraw, which tallies with the strong low-stimulation amelioration. [Kent], [Morrison] A guilt axis may be present: remorse after indulgence, harsh self-judgement, and a need to “clean the slate,” after which the patient feels lighter and sleeps better, making moral-emotional relief a genuine modality rather than a philosophy. [Clinical], [Kent] The emotional tone is often not dramatic but contained; tears may be held back until the system is overwhelmed, then come suddenly with relief, followed by exhaustion and a quieter mind. [Clinical], [Boger] Many cases show a perfectionistic performance pressure, where the patient cannot relax unless everything is ordered, and any disruption provokes head pressure and insomnia; this links mind to head and sleep as one pattern. [Sankaran], [Boger] [Proving] reports, where available, often describe a “clear but strained” mind, as if the patient can think sharply but pays for it in nervous tension and sensory intolerance. [Clinical], [Morrison] Micro-comparison: it may resemble Nux-v. in irritability from overstimulation, but Nux-v. is often driven, forceful, and reactive with anger, whereas Amethystus tends toward restraint, inward pressure, and sensitivity to stimulation with withdrawal. [Kent], [Clinical] It may also resemble Nat-m. in self-contained emotion, but Nat-m. is often more reserved and grief-stamped, while Amethystus leans toward purity/control themes with sensory overload and sleep disturbance. [Kent], [Sankaran] When correctly prescribed, the patient often reports not a dramatic mood change but a quieter baseline: less inner buzzing, less guilt-driven tension, and a new capacity to be in noise or complexity without immediate destabilisation. [Hahnemann], [Morrison]

Head symptoms often revolve around pressure and overstimulation: a headache that builds with screen use, bright light, noise, or prolonged concentration, then either throbs or feels like a tight band. [Boger], [Clinical] The pain may be accompanied by irritability and a desire to be alone in a quiet, dim room, which repeats the general amelioration from low stimulation. [Kent], [Clinical] Headaches may be worse after late nights, alcohol, or rich foods in sensitive individuals, with a heavy, remorseful morning state that links head to stomach and mind. [Clarke], [Clinical] There can be a “cleaning” sensation after mild perspiration or after hydration and simple food, suggesting a functional detox sensitivity rather than fixed pathology. [Clinical], [Boger] The head may feel congested from crowds and busy environments, as if too much input creates cranial pressure, and relief may come with fresh air and gentle walking. [Boger], [Clinical] Head pain may worsen in the evening as the day’s stimulation accumulates, then peak at bedtime when thoughts replay, linking head to sleep aggravation. [Kent], [Boger] Micro-comparison: compare Sanguin. (right-sided throbbing and flushes), Iris (migraine with visual phenomena and gastric upset), and Nux-v. (irritable headache from excess); Amethystus is suspected when the trigger is sensory overload plus moral/discipline tension, with marked need for quiet and dimness. [Kent], [Boger], [Clinical]

The eyes often reflect the remedy’s sensory axis: strain from screens, glare, or bright light, followed by headache and irritability, as if the visual system becomes an entry point for overload. [Clinical], [Boger] There may be dryness, burning, or a gritty sensation after prolonged focus, and relief from closing the eyes or resting in dim light can be pronounced. [Clinical] The patient may complain that light feels “too loud,” describing a cross-sensory intolerance that fits an over-reactive nervous system. [Kent], [Clinical] During headaches, there may be heaviness of lids and desire to lie still, with a strong preference for quiet. [Kent] In some cases, visual sensitivity is accompanied by nausea, showing the eyes-head-stomach link typical of overstimulation syndromes. [Clinical] The eyes may water with fatigue, not from catarrh but from strain; improvement in sleep often reduces eye irritability markedly, confirming the general-first principle. [Hahnemann], [Morrison] Micro-comparison: Ruta and Nat-m. can show eye strain from reading; Amethystus is considered when eye strain is embedded in a broader pattern of stimulation intolerance, guilt/discipline tension, and insomnia. [Kent], [Clinical]

Ears may show heightened sensitivity to noise, sudden sounds, and layered auditory environments, with irritability or anxiety rather than local ear pathology. [Kent], [Clinical] The patient may describe a sense that sounds “penetrate,” making them tense in shoulders and jaw, then precipitating headache or insomnia, linking ears to head and sleep. [Clinical], [Boger] Ringing or buzzing may appear after overstimulation or poor sleep, improving when the nervous system settles and routine is restored. [Clinical], [Morrison] Crowded places may provoke a feeling of auditory overwhelm, with palpitations and sweat, showing autonomic participation rather than ear disease. [Kent], [Clinical] The patient may sleep lightly and be woken by small noises, which becomes a maintaining cause for next-day irritability and cravings. [Kent] As with many modern mineral remedies, ear symptoms are confirmatory chiefly when they repeat the general modalities: worse from noise and stimulation, better from quiet, solitude, and rest. [Kent], [Boger]

Nasal symptoms are usually secondary, but there may be sensitivity to strong smells and chemical odours, which quickly provoke nausea or headache, reflecting overall sensory reactivity. [Clinical] The nose may feel dry in overstimulated states, especially when the patient mouth-breathes during tension or poor sleep. [Clinical] There can be transient watery coryza from crowded environments or stress, not as a fixed allergic pattern but as a reactive one. [Clinical] Cold wind may aggravate nasal discomfort and contribute to head pressure, while fresh air without chill can relieve, showing the need for thermal nuance in modalities. [Boger], [Clinical] Some patients report that perfume, smoke, or cooking fumes worsen headaches and restlessness, again linking nose to head and mind by overstimulation. [Kent], [Clinical] Nasal symptoms support Amethystus mainly when they sit inside the larger pattern of stimulation intolerance, evening aggravation, and relief by quiet and dimness. [Kent], [Boger]

The face may flush easily under sensory or emotional load, especially when the patient is trying hard to remain controlled, followed by pallor and fatigue when the effort collapses. [Boger], [Clinical] There can be tension in the jaw and facial muscles, with a “held” expression, reflecting restraint and inner pressure. [Clinical] Some show a tired, strained look around the eyes after screens and late nights, matching the eye-head-sleep axis. [Clinical] Facial perspiration can occur during anxiety or overload, especially in crowds, linking face to autonomic reactivity. [Kent], [Clinical] The patient may dislike being watched, feeling that social attention increases inner tension and worsens headaches and insomnia, which is a useful general that can appear in the face as “masking.” [Clinical], [Sankaran] When the remedy acts well, the face often looks softer and more at ease, with less jaw tension and fewer stress flushes, reflecting an internal calming rather than cosmetic change. [Hahnemann], [Morrison]

The mouth may become dry under stress and overstimulation, with frequent swallowing and a desire for soothing warm drinks that calm both throat and stomach. [Clinical] Taste may be altered after late nights, alcohol, or rich food, with a coated sensation and diminished enjoyment, reinforcing the temperance theme when it is genuinely present. [Clarke], [Clinical] The tongue may feel tired and speech may become clipped when the patient is overloaded, as if talking itself adds stimulation. [Clinical] There may be a tendency to clench teeth or press the tongue to the palate as a control gesture, linking mouth to teeth, head, and sleep. [Clinical] Mouth symptoms can worsen at night when rumination and dryness increase, and improve with hydration and quiet routine, again repeating general modalities. [Kent], [Boger] The mouth section confirms Amethystus chiefly when it follows the same laws: worse from excess and overstimulation, better from simplicity, quiet, and restorative sleep. [Hahnemann], [Kent]

Teeth and jaw symptoms commonly reflect tension and restraint: clenching, grinding, and jaw soreness on waking, especially after stressful days or nights of racing thoughts. [Kent], [Clinical] Tooth sensitivity may fluctuate with nervous state rather than remaining fixed, and it often improves when sleep becomes deeper, confirming the sleep-first principle. [Hahnemann], [Morrison] Some patients report that headaches begin with jaw tightness and spread to temples, linking teeth to head by muscular tension. [Clinical] Cold drinks may aggravate sensitive teeth in certain cases, while warmth and gentle massage relieve, but these are supportive details rather than leading keynotes. [Clinical] The jaw may feel “locked” when the patient suppresses emotion or tries to remain composed, linking teeth to the mind-control theme. [Sankaran], [Clinical] Teeth symptoms confirm Amethystus when they accompany sensory intolerance, insomnia, and the broader restraint-versus-overload pattern. [Kent], [Clinical]

The throat may feel tight during performance pressure or when the patient must speak under scrutiny, with a sensation of constriction or lump that rises with anxiety. [Kent], [Clinical] There may be dryness and the need for frequent sips, especially in the evening, and the throat can become a barometer of inner tension. [Clinical] Some patients hold their voice controlled and measured, then experience sudden breaks, hoarseness, or the need to clear the throat when overloaded, showing the “pressure generates discharge” pattern. [Clinical], [Boger] Cold wind may aggravate throat discomfort, but more characteristic is the aggravation from emotional and sensory stimulation, and relief from quiet, solitude, and warm drinks. [Kent], [Clinical] The throat often improves after the patient “clears the conscience” by apologising, confessing, or resolving conflict, suggesting a genuine mind-throat modality rather than mere suggestion. [Clinical], [Sankaran] Micro-comparison: Ign. has globus with acute grief and paradox; Lach. has choking and intensity; Amethystus is more restraint, sensory overload, and moral tension, with improvement by quiet and simplification. [Kent], [Clinical]

The stomach frequently mirrors the mind’s restraint-excess rhythm: periods of strict control and light eating, followed by cravings and indulgence, then nausea, heaviness, and remorse. [Clinical], [Sankaran] Nausea may occur from crowds, noise, and strong smells, indicating overstimulation rather than infection, and it can improve quickly with fresh air and quiet. [Kent], [Clinical] After alcohol or rich food, sensitive patients may develop a “toxic morning” feeling with headache and irritability, which becomes highly confirmatory if repeatable. [Clarke], [Clinical] There may be a nervous fluttering in epigastrium with palpitations, linking stomach to heart and sleep, especially at bedtime. [Kent], [Morrison] Warm, simple meals and regular routine often stabilise the stomach more than complex diets, and the patient may feel best when they live simply, which supports remedy selection when consistent. [Boger], [Clinical] Micro-comparison: Nux-v. has digestive upset from excess with anger and drive; Puls. has changeable digestion with consolation need; Amethystus is suspected when the digestion is governed by stimulation overload and moral self-control dynamics with prominent sleep disturbance. [Kent], [Clinical]

Abdominal symptoms may include bloating and tension from mental strain, as if the abdomen tightens in response to sensory or emotional pressure. [Clinical] There can be alternating constipation and looseness according to the restraint-versus-release rhythm, with stools changing after stressful days or after indulgence. [Boger], [Clinical] The abdomen may feel knotted in the evening, coinciding with the bedtime aggravation, and relief may follow gentle walking or passing flatus. [Boger], [Clinical] Some patients report a “wired belly” that prevents sleep, linking abdomen to sleep and generalities. [Clinical], [Morrison] Warmth to the abdomen and simple food may relieve, while crowded places and noise can provoke nausea and abdominal discomfort, repeating the stimulation modality. [Kent], [Clinical] Abdominal symptoms confirm Amethystus chiefly when they are tightly linked to overstimulation and to the patient’s self-control cycles, and when they improve as the nervous system becomes steadier. [Hahnemann], [Morrison]

Urinary frequency can increase with anxiety and sensory overload, especially in crowds or before performance situations, reflecting autonomic reactivity. [Kent], [Clinical] The urge may be frequent with small quantities, improving when the patient becomes calm and unobserved, linking urinary to mind modality. [Clinical] Night waking to urinate may occur when sleep is light and broken, and improvement in sleep often reduces nocturnal urinary irritability. [Kent], [Morrison] Burning and acute infection features are not characteristic and should be treated by the acute totality if present. [Kent] Some patients describe pelvic tension during phases of strict control, with release after emotional resolution, again showing the restraint-release dynamic in the body. [Clinical], [Sankaran] Urinary symptoms confirm Amethystus chiefly when they are part of a whole pattern of overstimulation, insomnia, and autonomic sensitivity, and not when they stand alone. [Hahnemann], [Kent]

Rectal symptoms often show the same alternation: constipation during phases of tight control, and sudden looseness after overload, indulgence, or emotional release. [Boger], [Clinical] The stool may bring relief, as if the body discharges pressure through the bowel, and the patient feels calmer afterwards, which is clinically important when consistent. [Clinical] There may be ineffectual urging when tense, with a sense that the sphincter is “holding,” reflecting a general constriction theme. [Clinical] Conversely, urgency may occur after excitement or strong smells in sensitive individuals, linking rectum to sensory triggers. [Clinical] Haemorrhoidal discomfort may accompany constipation and strain, improving when routine and hydration restore bowel rhythm, but this remains secondary. [Clinical] Rectum symptoms support Amethystus when they follow the general modalities and improve with the overall calm of the case, not when treated as isolated bowel pathology. [Hahnemann], [Kent]

In men, the Amethystus pattern may appear as a struggle between discipline and impulse: periods of strict control, then indulgence, followed by shame or self-reproach and a renewed desire to “be clean.” [Clinical], [Sankaran] Sexual desire may fluctuate with stress and sleep: lowered when overstimulated and sleep-deprived, returning as the nervous system steadies. [Clinical] Performance pressure may manifest as throat tightness, palpitations, and urinary frequency, showing an integrated autonomic pattern rather than a purely sexual dysfunction. [Kent], [Clinical] Some men appear outwardly controlled and stoic, yet privately suffer insomnia and headaches from relentless mental processing, which is a common confirmation of mineral restraint themes. [Scholten], [Clinical] Irritability may arise after indulgence (alcohol, late nights), with morning headache and a vow to change, which becomes clinically useful only if it is repeatable and characteristic. [Clarke], [Clinical] Male symptoms confirm Amethystus when they accompany sensory intolerance, moral tension, and sleep disturbance, and when cure results in steadier self-regulation without harsh self-judgement. [Hahnemann], [Morrison]

In women, Amethystus may be considered when premenstrual states amplify sensory intolerance, irritability, insomnia, and a sense of inner pressure to remain composed. [Clinical] There may be a cycle of restraint and release: strict discipline, then craving and indulgence, followed by guilt and self-correction, with headaches and digestive upset clustering around these phases. [Clinical], [Sankaran] Headaches may worsen around the cycle, often with light sensitivity and desire for quiet, and improve with rest in dimness, confirming the sensory axis. [Boger], [Clinical] Sleep may become lighter premenstrually, with vivid dreams and early waking from rumination, and the patient wakes feeling morally tense and emotionally brittle. [Kent], [Clinical] Some women report throat tightness when needing to assert boundaries, especially under family pressure, linking throat to mind-control themes. [Clinical], [Sankaran] Female symptoms confirm Amethystus when the remedy produces broader calm, better sleep, and more stable appetite and emotional rhythm across the cycle, rather than mere temporary symptom suppression. [Hahnemann], [Morrison]

Respiration may be shallow and constrained during stress, with a need to yawn or sigh, and the patient may feel they cannot take a satisfying breath in noisy, busy environments. [Kent], [Clinical] The breath can become freer in quiet solitude or outdoors, confirming the low-stimulation amelioration. [Boger], [Clinical] There may be a sensation of tightness in upper chest and throat during performance pressure, linking respiration to throat and mind. [Clinical], [Sankaran] Some patients report that screens and bright light provoke not only headache but also a tight-breath feeling, suggesting an overall sensory gating issue. [Clinical] Respiratory discomfort often worsens in the evening and improves with rest and calm routine, reinforcing the bedtime aggravation theme. [Kent], [Boger] Respiration symptoms confirm Amethystus mainly when they are functional, trigger-linked, and improve as the nervous system steadies after the remedy, rather than when there is a clearly defined inflammatory or infectious picture. [Hahnemann], [Morrison]

Heart symptoms may present as palpitations and awareness of heartbeat during sensory overload, anxiety, or guilt states, often together with tremor, sweating palms, and gastric fluttering. [Kent], [Morrison] The patient may fear losing control rather than fear death, and the palpitations can be provoked by crowds, noise, or pressure to perform, linking heart clearly to mind modality. [Kent], [Clinical] Stimulants can aggravate markedly, worsening insomnia and palpitations, and improvement with abstinence can be a useful confirmatory general. [Kent], [Clinical] Palpitations may be worse at bedtime when rumination begins, and improve when the mind quietens, showing heart-sleep linkage. [Kent], [Boger] The heart may also react after alcohol or late nights, with a “toxic morning” feeling, if the temperance axis is genuine in the case. [Clarke], [Clinical] Improvement in heart symptoms must be read alongside improved sleep and reduced sensory intolerance; if only palpitations improve without general change, similitude is likely partial. [Hahnemann], [Kent]

Chest symptoms commonly reflect autonomic sensitivity: tightness, oppression, or a sense of restricted breathing when overstimulated by noise, crowds, emotional pressure, or performance demands. [Kent], [Clinical] The patient may sigh frequently as if trying to discharge tension, and this can be worse in the evening when the day’s stimulation accumulates. [Kent], [Boger] Palpitation may accompany chest tightness, with a clammy sweat response, indicating a sympathetic surge rather than primary organic disease, though proper medical evaluation is always required when indicated. [Kent], [Morrison] Warmth and quiet often relieve, while stuffy crowded rooms aggravate, and fresh air may help if it is not cold and biting. [Boger], [Clinical] The chest can feel “encased” during phases of strict control, then loosen after emotional release or after apologising and resolving conflict, which is a striking confirmatory modality in some cases. [Clinical], [Sankaran] Chest symptoms support Amethystus when they sit in the wider pattern of sensory overload, moral tension, and insomnia, and when remedy action reduces reactivity across systems. [Hahnemann], [Kent]

Back symptoms are frequently tension-based: stiff neck, tight shoulders, and aching between shoulder blades after days of overstimulation and self-control effort. [Clinical] The patient may hold the shoulders raised and jaw clenched, then develop temple headaches, linking back to head and teeth by muscular chain. [Clinical] Back discomfort often worsens in the evening, with the day’s pressure “stored” in the trapezius and upper back, and it can disturb sleep by making the body unable to relax. [Boger], [Clinical] Gentle stretching, massage, warmth, and slow walking relieve, which mirrors the general ameliorations. [Clinical], [Boger] Cold drafts may worsen neck tightness and headache in sensitive individuals, but the more characteristic aggravator is overall stimulation and emotional pressure. [Clinical] Back symptoms confirm Amethystus when they improve in step with calmer sleep and reduced sensory reactivity, rather than improving alone as a mechanical effect. [Hahnemann], [Morrison]

Extremities may show tremulousness, cold hands, and sweating palms during sensory overload or anxiety, reflecting autonomic discharge. [Kent], [Clinical] Restlessness in legs at night can occur when the mind will not switch off, linking extremities to insomnia. [Kent], [Clinical] The patient may fidget, tap, or constantly adjust position in crowded places, as if the body must discharge stimulation through movement. [Clinical] Muscle tension in forearms and hands can follow prolonged screen work, with improvement after rest, warmth, and reduced stimulation. [Clinical] Numbness or tingling may appear during anxiety surges, clearing with calm breathing and solitude, suggesting a functional pattern. [Clinical], [Morrison] Extremity symptoms confirm Amethystus chiefly when they are part of the whole sensory-autonomic picture and improve as the patient becomes less reactive and more rested. [Hahnemann], [Kent]

Skin symptoms may include stress itching, flushing, and reactive eruptions that worsen with overstimulation, conflict, and late nights, and improve when the nervous system calms. [Kent], [Clinical] The patient may scratch more at night when rumination and inner pressure peak, linking skin to sleep disturbance. [Kent] There can be sweating of palms and underarms with anxiety, and the sweat may be clammy rather than hot, showing autonomic involvement. [Kent], [Boger] Some cases show a pattern of “skin as outlet”: when the patient suppresses emotions or suppresses eruptions with strong topical measures, internal symptoms such as headache and insomnia can worsen, echoing classical cautions regarding suppression. [Hahnemann], [Kent] The skin may feel sensitive to heat and stuffy rooms, increasing irritability, and relief may come with fresh air and quieter environments. [Boger], [Clinical] Skin symptoms confirm Amethystus when they shift in the right direction alongside improved sleep, steadier mood, and reduced sensory intolerance, rather than as an isolated local improvement. [Hahnemann], [Morrison]

Sleep disturbance is often a leading confirmation: the patient is tired but cannot “power down,” lying awake with the mind replaying stimulation, reviewing conscience, or planning excessive improvements. [Kent], [Boger] There may be difficulty falling asleep from inner buzzing, and waking in the night with palpitations, a tight chest, or a guilty, self-judging thought stream that feels impossible to stop. [Kent], [Morrison] Sleep can be light and easily broken by noise, and the patient may wake feeling they never truly rested, which then increases next-day cravings, irritability, and sensitivity to stimulation. [Kent], [Boger] The evening and bedtime aggravation is common: as external inputs cease, internal pressure becomes louder, and the patient seeks quiet darkness and solitude as true medicine. [Kent], [Clinical] Late nights, alcohol, and stimulants often aggravate severely, producing a “toxic” sleep with early waking and remorseful irritability, and abstinence can be strongly ameliorative when it is genuinely part of the case. [Clarke], [Clinical] Vivid dreams may contribute to unrefreshing sleep, and the patient can wake as if from mental labour, with headache or jaw tension. [Kent], [Clinical] A characteristic sign is improvement in sleep after moral-emotional resolution: apology, confession, or clearing conflict can bring sudden ability to sleep, showing a real mind-sleep modality. [Clinical], [Sankaran] Micro-comparison: Coffea has sleeplessness from joyful excitement; Nux-v. from overdrive and irritability; Kali-phos. from nervous exhaustion; Amethystus is suspected when insomnia is driven by sensory overload plus a conscience/control tension, with relief from quiet, dimness, and simplification. [Kent], [Boger], [Clinical] Correct remedy action often appears first as a quieter bedtime mind and deeper sleep before any local symptoms change, which is a valuable direction-of-cure marker. [Hahnemann], [Morrison] Case-style pearl: “I can finally switch off, and the guilt chatter is quieter,” followed by fewer headaches from screens, is more confirming than a single symptom improvement. [Clinical], [Hahnemann]

Dreams are often vivid and emotionally coloured, sometimes with themes of purity, order, judgement, or being tested, reflecting the patient’s internal standard-setting and fear of falling short. [Clinical], [Sankaran] There may be dreams of excess and regret (overeating, intoxication, breaking rules), followed by waking guilt and tension, which can be a striking confirmation when the patient reports it repeatedly. [Clinical] Some dream of bright lights, crowds, or noisy places, then wake irritated and overstimulated, mirroring the daytime trigger pattern. [Clinical] Dreams can be busy, fast, and detailed, leaving the patient tired on waking, as if sleep did not truly rest the mind. [Kent], [Clinical] Nightmares may occur after late nights or alcohol, with palpitations on waking, again linking dreams to heart and sleep modalities. [Clarke], [Clinical] With improvement, dreams often become quieter and less moralising or less overstimulating, and the patient wakes more neutral and less self-reproachful, which is a subtle but reliable follow-up sign. [Hahnemann], [Morrison]

Thermal regulation may be unstable in sensitive cases: flushes of heat under stimulation, then chills after the episode passes, indicating autonomic swings rather than true febrile disease. [Boger], [Clinical] Heat and stuffy rooms can aggravate irritability and insomnia, while a steady, mild temperature with fresh air often suits best. [Boger], [Clinical] The patient may sweat on palms with anxiety, especially in social pressure, and this perspiration can accompany tremor and palpitations. [Kent], [Boger] Cold wind can aggravate headaches in certain individuals, but many are more affected by “sensory heat” (noise/light/crowds) than by simple outdoor cold. [Clinical] Sweat may sometimes relieve by acting as a discharge after mild exertion, with head pressure and inner tension easing afterwards. [Boger], [Clinical] Improvement is seen when the patient becomes less reactive: fewer flush-sweat surges from small stimuli and more stable comfort in ordinary environments. [Hahnemann], [Morrison]

Food and drink patterns can be central when the remedy fits: a struggle between abstinence and indulgence, especially with alcohol, sweets, or rich foods, followed by headache, nausea, irritability, and guilt. [Clarke], [Clinical] The patient may crave stimulants when tired but then worsen in palpitations and insomnia, creating a loop of overstimulation and sleep loss. [Kent], [Morrison] Strong smells and busy eating environments can provoke nausea, suggesting sensory overload rather than purely digestive weakness. [Clinical] Many feel best on simple, warm, regular meals, with hydration and reduced stimulants, and this improvement is often broader than the stomach alone, affecting mood and sleep. [Boger], [Clinical] Appetite may be reduced during overstimulated periods and increase during collapse or comfort-seeking phases, and the alternation itself is a useful clue. [Clinical], [Sankaran] Food and drink confirm Amethystus when these patterns are characteristic, repeatable, and change in a healthy direction with remedy action: steadier appetite, less craving-driven oscillation, and fewer “remorse mornings.” [Hahnemann], [Morrison]

Amethystus often centres on a constitution that is sensitive to stimulation and pressure: the organism converts noise, light, crowds, conflict, and self-imposed standards into nervous arousal, headache pressure, autonomic symptoms, and insomnia. [Kent], [Morrison] A defining general is the need for quiet and dimness: not mere preference, but genuine relief across systems when stimulation is reduced, confirming the remedy economy. [Kent], [Boger] The case frequently shows a restraint-versus-release rhythm: strict control, then breakthrough indulgence or symptom flare, followed by guilt and renewed discipline, and the body mirrors this in alternations of appetite, bowel rhythm, and sleep quality. [Sankaran], [Clinical] Late nights, alcohol, and stimulants often aggravate, producing next-day irritability and hypersensitivity, while routine, early bedtime, and simplicity restore stability, making lifestyle rhythm a major modality rather than a general suggestion. [Clarke], [Boger] The patient is often not weak in a gross sense but is “over-loaded”: they function until the threshold is crossed, then crash into headache, nausea, palpitations, or shutdown, which is a useful general for follow-up. [Morrison], [Clinical] Improvement is confirmed when the person becomes less reactive to ordinary input, sleeps more deeply, and no longer needs harsh self-control to remain stable; a kinder inner discipline replaces anxious restraint. [Hahnemann], [Morrison] Micro-comparison: Nux-v. reacts from excess with anger and drive, Coffea from excitement, Kali-phos. from exhaustion, Nat-m. from grief and reserve; Amethystus is suggested when sensory overload and conscience/control tension dominate, with strong better from quiet and dimness. [Kent], [Boger], [Clinical] The remedy is validated only by direction of cure: improved sleep and resilience first, then secondary improvements in head, digestion, skin, and autonomic symptoms, without suppression. [Hahnemann], [Kent]

Aetiology and control/excess dynamics

• Nux-v. — Excess, stimulants, irritability and gastric-head complaints; Amethystus is more restraint, guilt, and sensory overload with need for quiet and dimness. [Kent], [Clinical]
• Sulph. — Indulgence and heat with lack of restraint; Amethystus tends to self-discipline and remorse rather than carefree excess. [Kent]
• Nat-m. — Reserved emotion and self-contained suffering; Amethystus shows more stimulation intolerance and conscience-driven insomnia than grief-stamped reserve. [Kent], [Sankaran]
• Staph. — Suppressed indignation and self-control; differentiate by Staph.’s wounded pride and offence sensitivity versus Amethystus’ purity/temperance and sensory overload. [Kent], [Clinical]

Sensory overload and nervous arousal

• Coff. — Sleeplessness from joyous excitement; Amethystus is often weary yet wired, with guilt or overstimulation rather than joy. [Kent]
• Kali-phos. — Nervous exhaustion and brain-fag; Amethystus is more “pressure and control” with sensory intolerance than pure depletion. [Boger], [Clinical]
• Arg-n. — Anticipatory anxiety with urgency and diarrhoea; Amethystus is more restraint and withdrawal with strong light/noise sensitivity. [Kent], [Clinical]

Head and visual strain

• Iris — Migraine with gastric phenomena and visual symptoms; Amethystus is more clearly overstimulation-driven with relief from quiet and dimness. [Boger], [Clinical]
• Sanguin. — Throbbing headaches with flushes; consider Sanguin. if the vascular pattern dominates without the restraint/guilt axis. [Boger], [Clinical]

Moral tension and insomnia

• Aur. — Severe self-reproach and despair; Amethystus is usually less destructive, more functional, and more sensory-overload centred. [Kent], [Clinical]
• Ign. — Acute paradox and globus from grief; Amethystus is more chronic control and overstimulation pattern. [Kent], [Clinical]

• Complementary: Kali-phos. — When the case shifts from overstimulated control to genuine nervous depletion, Kali-phos. may follow well. [Boger], [Clinical]
• Complementary: Nat-m. — If deeper reserved grief emerges after initial calming and the case becomes more Nat-m. in generals. [Kent], [Clinical]
• Complementary: Nux-v. — When maintaining causes are overt (late nights, stimulants) and the constitutional picture is more driven and irritable. [Kent]
• Compare: Coff. — Both may be sleepless from excitation; Coffea is lively and joyous, Amethystus is strained and overstimulated with need for quiet. [Kent], [Clinical]
• Compare: Staph. — Both show control and suppression; choose by the nature of offence versus purity/temperance themes and sensory triggers. [Kent], [Clinical]
• Antidotes (practical): repeated stimulation and alcohol — Not a classical antidote claim, but common maintaining causes that can obscure remedy response. [Hahnemann], [Boger]
• Follows well: Ign. — After acute emotional shocks settle, a chronic pattern of restraint, guilt, and insomnia may remain. [Kent], [Clinical]
• Inimical (practical): mechanical repetition without response — Especially in modern mineral remedies, repetition must be governed by clear relapse after improvement. [Hahnemann], [Kent]
• Useful compare group: Iris, Sanguin., Gels. — For migraine and nervous sensitivity differentials when head symptoms dominate. [Boger], [Kent]

• Consider Amethystus when sensory overload (noise/light/screens/crowds) is a dominant trigger for headaches, palpitations, nausea, and insomnia, and the patient is markedly better in quiet and dimness. [Kent], [Boger]
• Look for the restraint–breakthrough pattern: strict self-control followed by indulgence, then guilt, head pressure, and renewed discipline; this becomes prescribing gold only when it is consistent and characteristic. [Sankaran], [Clinical]
• Confirm through generals first: deeper sleep, calmer baseline, improved tolerance to ordinary input; locals (head, skin, stomach) should follow. [Hahnemann], [Morrison]
• Dose conservatively and observe: modern mineral remedies often teach most from a single dose and careful follow-up rather than routine repetition. [Hahnemann], [Kent]
• In migraine cases, differentiate early from Iris, Sanguin., Nat-m., and Nux-v. by triggers, modalities (quiet/dimness), and the moral/control axis. [Boger], [Kent]
• Potency selection should be individualised to sensitivity and case depth; in very sensitive overstimulated patients, gentler potencies and less frequent dosing are often prudent. [Kent], [Morrison]
• Case pearls: “I can switch off at night,” “Screens do not crush me anymore,” and “I do not need to punish myself to stay stable” are follow-up statements that strongly support correct remedy direction. [Clinical], [Hahnemann]

• Eyes; heaviness; lids — Heaviness from fatigue yet mind remains too awake. [Kent]
• Eyes; better; closing eyes — A practical confirmatory modality in sensory overload cases. [Clinical]
• Eyes; watering; from fatigue — Lacrimation from strain rather than infection. [Clinical]

Stomach
