• Blood and Red Cells — haemolysis, pallor, dark urine, exertional collapse; central to its sphere and echoed under Fever/Generalities [Hughes], [Clarke].
• Spleen and Reticuloendothelial System — fullness, tenderness, stitch-like pains, especially with motion; compare Ceanothus; see Abdomen/Spleen [Boericke], [Clarke].
• Liver and Bile — low-grade cholestatic hints with nausea and right hypochondrial discomfort during paroxysms; see Abdomen [Hughes], [Clarke].
• Autonomic/Vasomotor — alternating chill and sweat, temperature lability, clammy skin; see Chill/Heat/Sweat [Boger], [Kent].
• Lungs/Respiration — “air hunger,” sighing, worse least exertion; relief from cool air and sitting up; see Respiration [Clinical], [Boger].
• Heart/Circulation — tachycardia, palpitations during fever or anaemia, orthostatic faintness; see Heart [Clarke], [Morrison].
• Musculoskeletal — deep myalgia and bone-ache “as if broken,” reminiscent of Eupatorium yet with more dyspnoea; see Extremities [Kent], [Boericke].
• Nervous System — dull confusion, “fog,” anxiety from hypoxia during paroxysm; see Mind/Head [Clinical], [Vithoulkas].
• Skin/Exocrine — profuse nocturnal perspiration, sour or slightly musty odour; see Perspiration [Boger], [Boericke].
• Kidneys/Urine — haemoglobinuria or dark urine after fever bouts; see Urinary [Hughes], [Clarke].

• Cool, fresh air; windows open—eases air hunger (echoed under Respiration) [Boger], [Clinical].
• Sitting propped up (orthopnoea), head and chest elevated (see Respiration/Heart) [Clinical], [Boericke].
• Gentle pacing rather than exertion—keeps panic of dyspnoea down (see Generalities) [Vithoulkas], [Clinical].
• Rest in short intervals during paroxysm—prevents collapse (see Generalities/Fever) [Kent], [Clinical].
• Sipping cool water—relieves heat and palpitations during fever (see Stomach/Food & Drink) [Boericke].
• Loosening tight clothing—releases chest oppression (see Chest/Respiration) [Clinical].
• After perspiration breaks—the “crisis sweat” ushers temporary clarity (see Chill/Heat/Sweat) [Boger].
• Pressure/warmth to spleen region for stitch-pains (see Abdomen) [Clarke].
• Quiet, reassurance—calms anxiety of suffocation (see Mind) [Vithoulkas].

• Exertion, even slight—climbing stairs, talking fast (air hunger, tachycardia; see Respiration/Heart/Generalities) [Boger], [Clinical].
• Heat of bed before sweat arrives—provokes restlessness and dread (see Sleep/Chill/Heat) [Kent].
• Damp-warm weather or sudden weather shifts—triggers paroxysms (see Fever) [Boger], [Clarke].
• Afternoon to evening periodicity; some cases pre-dawn aggravation with sweats (see Fever/Sleep) [Boger], [Sankaran].
• Lying flat—brings on oppression and palpitations (see Respiration/Heart) [Clinical].
• Hunger/fasting—weakness and faintness from anaemia (see Stomach/Generalities) [Hughes].
• Emotional strain with fear of suffocation—panic worsens dyspnoea (see Mind/Respiration) [Vithoulkas].
• After tick bite or after malarial-type fevers—relapses (see Generalities/Aetiology) [Clarke].
• Alcohol and overheating—flush, palpitation, heavy head (see Head/Heart) [Boericke].

Anxiety centres on breathing and the next attack, with a distinct dread that the chest will “forget to breathe,” a flavour of panic that abates once cool air is obtained [Clinical], [Vithoulkas]. There is irritability from exhaustion; the sufferer resents interruption and seeks quiet, with a stifled, inward restlessness resembling Arsenicum, yet here fear is tied to air hunger more than to burning pains [Kent], [Clinical]. A sense of vulnerability alternates with brief spells of normality, the malarial miasm’s oscillation between illness and apparent health [Sankaran]. Memory dullness and “fog” appear after the paroxysm; the mind feels cotton-woolly, a state attributed to hypoxia/anaemia and cytokine aftermath [Hughes], [Clinical]. Low confidence with anticipatory anxiety precedes exertion (climbing stairs, speaking in groups) because of expected breathlessness; this tallies with the aggravation from exertion already noted (Worse For) [Boger]. Oversensitivity to heat and closed rooms produces fretfulness until windows are flung open, cross-linking with the amelioration from fresh air (Better For) [Boericke]. There may be a sombre, withdrawn mood in the afternoon, brightening after the sweat crisis; patients often report feeling “more themselves” post-sweat [Boger]. Fear of death comes in waves during palpitations—brief but intense—followed by resignation and sleepiness [Kent]. Mini case: “At 4 p.m., panic with gasping, grasping window, quiets within minutes of cool air; slept after sweat” [Clinical]. The general psychological polarity is between episodic alarm and inter-paroxysmal normality, an inner signature of the malarial miasm [Sankaran], [Vithoulkas].

Head feels heavy, muzzy, and hot during chill/heat phases, with a congestive fullness that improves once perspiration sets in, aligning with the noted improvement after “the sweat breaks” (Better For) [Boger], [Clarke]. Dull occipital ache accompanies neck stiffness, worse lying flat (orthopnoea posture relieves), linking to the respiratory aggravation on the flat back [Clinical]. Vertigo on rising is common in anaemic states, with blackness before eyes and a need to sit; compare China and Ferrum for post-febrile anaemia [Nash], [Boericke]. Temporal throbbing with palpitations suggests autonomic overdrive; cool sponging offers brief relief [Kent]. Brain-fog is prominent after paroxysm—slow thinking, misplacing words—clearing transiently with fresh air (cross-link to Better fresh air) [Vithoulkas], [Clinical]. Some complain of a tight band sensation, evening worse, correlating with the periodicity observed under Fever [Boger].
