Nitromuriaticum acidum
Aqua regia (nitrohydrochloric acid) · Human-made/chemical
Nitromuriaticum Acidum suits bilious, hepatic constitutions in persons living in hot, damp climates who consume excess meat and alcohol. There is hepatic torpor with mouth ulceration, ptyalism, and oxaluria. It removes distressing skin symptoms resembling psoriasis associated with hepatic and oxalic acid disorders.
Key symptoms
- Oxaluria with cloudy urine and burning in urethra
- Torpid liver, hepatitis, and early cirrhosis aggravated by meat and alcohol in hot, damp climates
- Constricted anus with constipation and ineffectual urging; anus moist and sore
- Bleeding gums, ptyalism, and constant drooling at night
- Aphthous ulcerations over inside of mouth and tongue; metallic taste
- Sour eructations with empty hungry feeling not relieved by eating
- Salivation worse at night
Worse (aggravation)
- Night (salivation and drooling)
- Meat eating and alcohol
- Hot and damp climates

Clinical

Characteristics
Nit. mur. ac. has been proved in the lower dilutions and in the 30th; and some experiments have been made by Dr. Scott (quoted C. D. P.), who acidulated his bath with the acid, and sponged his body with acidulated water. Sponging and bathing had the same effect, and I have marked his symptoms with (b) in the Schema. Scott noticed that the symptoms were more marked as the proportion of Muriatic acid was increased. Salivation and sore mouth and throat with dysphagia were produced in Scott and the provers. Scott noticed that the salivation was intermittent. Weakness was felt by all. Headache with drowsiness. Slow digestion. Pricking pains. Symptoms were < after eating and by exercise. Nat. mur. ac. has a clinical reputation in oxaluria and gravel.
