People for whom Muriatic ac. is most appropriate tend to feel too weak to move. Drowsy by day, but restless in bed, they have anxious dreams and are prone to talking in their sleep. They may be either sad and reserved or loquacious. Often irritable and fretful, their minds may be crowded with thoughts. 

This remedy is typically prescribed for  weakness or physical collapse, such as that associated with chronic fatigue syndrome, or developing after a feverish illness such as mononucleosis or typhoid. The muscles, especially those of the heart, tongue, bladder, and anus, may be weak, exhausted, or partially paralyzed. 

Muriatic ac. is given when the collapsed  state is associated with dryness, bleeding, and ulceration of the mucous membranes of the mouth and digestive tract. A heavy tongue and dry mouth may make talking difficult, and deep-seated ulcers or small tumors may develop on the tongue.

Key symptoms

  • Extreme prostration; patient slides down in bed from weakness
  • Septic conditions with decomposition of fluids and hemorrhages
  • Tongue pale, swollen, dry, leathery, paralyzed with deep ulcers
  • Involuntary stool while passing urine
  • Uvula swollen; ulcers and false membrane in throat
  • Mouth and anus chiefly affected; sordes on teeth

Worse (aggravation)

For wet weather; for touch; for bathing in the sea; during menstruation; for cold drinks; for sliding down in bed.

Better (amelioration)

For warmth; for movement; for lying on the left side.

When treating a low form of continued fever with extreme prostration Arsenicum, Muriatic acid and Phos. acid force themselves upon the mind.

With Arsenicumthere has been the anxious restlessness; with Phos. acid there has been the mental prostration, and then the muscular weakness; with Muriatic acid the muscular weakness comes first, and there has been history of restlessness and the mind has been stronger than could be expected.

With this great muscular exhaustion with jaw hanging down and the patient sliding down in bed and soon the involuntary stool and urine, this remedy is forced upon the mind. Paralytic weakness is what it must be called.

Characteristics

The popular name of Mur. ac., "Spirit of Salt," describes at once its nature and origin. It is a colourless gas, with a pungent, suffocating odour, and acid taste, and it is manufactured from Salt (Nat. m.) by the action of sulphuric acid. It is freely soluble in water, and the saturated solution contains 43 per cent. of the gas. Teste, who did much to define the powers of Mur. ac., groups with it Agn. cast. and Hyos., and he considers its action corresponds perfectly to a typical case of typhus. Among the common features of the group he gives; …
