This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.

What Nitricum Acidum is used for

  • Anal fissures and cracks with sharp, splinter-like pain
  • Warts, especially large, jagged, or bleeding ones
  • Mouth ulcers and cracks at the corners of the mouth
  • Ulcers with a stinging, splinter-like sensation

Characteristic symptom picture

Homeopaths look for these guiding features when considering Nitricum Acidum.

  • Sharp pains as if from a splinter
  • Cracks and fissures where skin meets mucous membrane
  • Warts that may bleed on washing or contact

  • Anxious about health, irritable, and unforgiving

Potency

Nitricum Acidum is available in several potencies such as 6C, 30C and 200C, as well as lower and mother-tincture forms in some cases. The right potency and repetition depend entirely on the individual case and are decided by a qualified homeopath - this page gives no dosing instructions.

The Nitric Acid picture and modalities

Nitricum Acidum is defined by sharp, splinter-like pains and by trouble at the junctions of skin and mucous membrane - fissures at the anus, cracks at the corners of the mouth, and warty growths that may bleed. Discharges tend to be offensive and the urine strong-smelling. The temperament is often anxious about health, irritable, and slow to forgive. A homeopath weighs these keynotes together with the whole constitution rather than singling one out.

Before you consider Nitric Acid

This is background information, not a recommendation to self-treat. Persistent fissures, bleeding warts, or non-healing ulcers should be examined by a doctor, since they can have causes that need proper diagnosis and, sometimes, surgical care. In homeopathy the right remedy and potency are chosen for the whole individual by a qualified practitioner, and the same remedy does not suit everyone. Homeopathy should complement, not replace, conventional care.
