• Myocardium (Nutrition & Tone). Cardiac muscle trophic effect; improves contractility and endurance in failure from degeneration, especially senile or post-infective hearts [Hale], [Ellingwood], [Clarke].
• Coronary Circulation. Angina pectoris, coronary insufficiency, precordial oppression, pains to left arm; diminishes frequency and severity of attacks [Clarke], [Boericke].
• Conduction & Rhythm. Palpitation, extra-systoles, functional arrhythmias of tobacco/coffee, nervous strain; heartbeat less labile under treatment [Hale], [Boericke].
• Valvular Disease. Mitral and aortic lesions with dyspnoea, oedema, and cyanosis; palliative strengthening without Digitalis-like cumulative effects [Clarke], [Ellingwood], [Boericke].
• Vessels & Blood Pressure. Moderates arterial tension; useful in arteriosclerosis with head rush, vertigo, and tinnitus; reduces vascular irritability [Hale], [Clarke].
• Respiratory Consequence of Heart Disease. Cardiac dyspnoea, orthopnoea, night cough from cardiac weakness; breathing freer after doses [Boericke], [Clarke].
• Nervous System (Cardiac Anxiety). Fear of death from the heart, insomnia from cardiac awareness, inter-attack neurasthenia [Hale], [Nash], [Clarke].
• Renal–Serous. Cardiac dropsy—oedema of feet/ankles, scant urine—improves as the heart strengthens (indirect diuresis) [Boericke], [Ellingwood].
• Digestive (Reflex). Flatulence and epigastric weight reflexly aggravate cardiac oppression; relief as cardiac tone rises [Clarke], [Hale].

• Rest, absolute physical quiet after exertion [Clarke], [Boericke].
• Sitting propped up; head raised; short naps in that posture (orthopnoea relief) [Boericke], [Hale].
• Open cool air or gentle ventilation; dislikes confined rooms [Clarke].
• Slow, even walking after initial rest—when strength begins to return (cardiac training effect) [Hale].
• Warmth to chest; light shawl; avoids chilling (vasomotor stability) [Clarke].
• Small, frequent sips of cool water during anxiety palpitations [Hale].
• Letting wind (eructations) when flatulence presses up under sternum [Clarke].
• Steady routines; regular hours reduce nocturnal cardiac awareness [Nash].
• Avoiding stimulants (tobacco, strong tea/coffee); palpitation subsides [Boericke].
• Reassurance/company; fear of cardiac arrest lessens [Hale].

• Exertion—especially climbing, hurrying, or going upstairs (instant dyspnoea) [Clarke], [Boericke].
• Emotion, anxiety, or sudden alarm—palpitation and precordial pain flare [Hale], [Nash].
• After meals, particularly heavy or fatty food—cardiac oppression/eructation [Clarke].
• Lying flat; must sit up in bed to breathe (orthopnoea) [Boericke].
• Night, especially after midnight—panic-waking with heart awareness [Hale], [Tyler].
• Cold, damp weather or sudden changes of temperature [Clarke].
• Stimulants (alcohol, tobacco, coffee)—irritable heart, tremor [Boericke], [Hale].
• Tight clothing over precordia—sensation of band and weight [Clarke].
• Mental strain (long study, worry) and sleep loss—heart flutters [Nash].
• Suppression of habitual perspiration; chill to chest brings night symptoms [Clarke].

The emotional field bears a cardiac stamp: a quiet, apprehensive anxiety centred on the heart, with fear of dying in sleep or of sudden arrest on exertion; despite this fear the demeanour is more timid and resigned than dramatic (contrast Acon.) [Hale], [Clarke], [Nash]. Cardiac awareness intrudes on attention—patients count beats or wake to listen to the heart, then cannot recompose the mind for rest (Sleep cross-link) [Hale], [Tyler]. During anginoid oppression the mind is still and watchful, avoiding movement; a dread of stairs forms, learnt by repeated dyspnoea [Clarke]. Irritability is mild but worry about health and dependants recurs, made worse by palpitation and nocturnal breathlessness (Modalities worse night, exertion) [Hale], [Boericke]. Confidence rises in step with improved cardiac tone; some describe a calmer temper once oppression abates—an indirect proof of the functional basis [Ellingwood], [Clarke]. In arteriosclerotic states the memory flags late in the day, with head rushes and tinnitus that reawaken fear—these settle with regular Crat. dosing and moderated habits (Affinity: Vessels) [Hale], [Clarke]. The mental picture lacks the tragic intensity of Cactus or Aurum; it is a soft, anxious quiet, tied by short cords to the breath and pulse [Boericke], [Nash]. Reassurance and company ease symptoms (Better companionship), but sudden alarms—doorbell at night, unexpected knock—shoot straight to the heart with instant palpitation (Worse emotion) [Hale]. Thus the Mind is the barometer of myocardium: as dyspnoea and oppression recede, fear and watchfulness melt [Hale], [Clarke], [Ellingwood], [Boericke].

Head suffers from vascular tone changes: fullness, throbbing, or a momentary rush of blood on rising; in arteriosclerosis, dizzy spells with tinnitus and dim sight (Vessels Affinity) [Clarke], [Hale]. Headache follows hurrying or climbing, the face pale and anxious while the pulse flutters (Generalities link) [Boericke]. When heart steadies under Crat., head becomes clear, tinnitus abates, and memory steadies through the evening (Relationship to blood pressure) [Clarke]. Occipital weight at night with insomnia from heart awareness (Sleep) [Hale]. Headaches are seldom violent; they mirror the heart—a pressure or band that eases as precordial oppression lifts [Clarke], [Boericke]. Some note frontal pressing after rich food with epigastric distension, again relieved by eructations (Digestive cross-link) [Clarke].
