Muriaticum acidum

Muriaticum acidum is a solution of hydrogen chloride gas in water—commonly known as hydrochloric acid, a corrosive, highly acidic compound used industrially. In homeopathic form, it acts primarily on the vital force, particularly when it is low or exhausted. It reflects a deep debility, with mental indifference and physical prostration. It affects the mucous membranes, rectum, nervous system, and the circulatory system, showing signs of ulceration, involuntary discharges, and internal haemorrhaging.

Proved by Dr. Hahnemann and his students; symptoms developed through toxicological accounts and clinical confirmation.

Muriaticum acidum reflects the collapse of life force, marked by mental apathy, physical prostration, and ulcerative discharges. There is no will to resist—life seems too heavy to carry. The body is falling apart, with haemorrhages, ulcers, and incontinence. The soul has retreated into silence. Its essence lies in the quiet death-like state, where the patient may not cry out but is slowly sinking inward. It is a remedy of final stages, yet also of transformation, where intervention may arrest the descent into fatality.

• Rectum and anus – prolapse, ulceration, incontinence
• Mucous membranes – mouth, throat, genitalia
• Circulatory system – haemorrhagic tendencies
• Nervous system – extreme prostration, unconsciousness
• Skin – ulcers, bedsores, eruptions with blue surroundings
• Vital force – low states after acute diseases or exhaustion
• Mental state – indifference, stupor, apathy

Profound mental dullness, apathy, and indifference dominate the mental picture. The patient lies in bed without complaint, unwilling or unable to speak, scarcely answering when spoken to [Hering]. Despite this apparent resignation, there may be internal restlessness or an urge to flee. Memory weak; unable to concentrate. Loathes life, but lacks strength for suicide. Delusions that people are looking at him with disdain. Anxiety alternating with prostration. Children moan or whimper during sleep without waking. In severe cases, unconsciousness or muttering delirium develops. Suited to low states after serious illness, especially when the mind appears detached and the will is failing.

Palpitations from weakness. Pulse weak, soft, intermittent. Cold extremities with weak circulation. Cyanosis. Fainting spells, particularly on sitting up or standing. Dyspnoea on exertion.

Rapid, shallow breathing. Dyspnoea worse from exertion or lying flat. Breathing may cease for moments, especially in elderly or fever patients. Rattling in chest without expectoration. Cannot draw a full breath.
