Nitric Acid (Acidum Nitricum, or Nitricum Acidum) is a deep-acting homeopathic remedy made from the mineral acid that alchemists once called aqua fortis, “strong water.” In potentized form it is one of the most valuable remedies for a very particular group of complaints: sharp, splinter-like pains, painful cracks and fissures at the openings of the body, warts, and discharges so offensive they are hard to be near. This article explains what Nitric Acid is, the symptoms it treats best, the type of person who needs it, and how to use it safely at home.
What Is Nitric Acid? Overview and History
Nitric acid is a corrosive mineral acid first prepared by distilling saltpetre (potassium nitrate) with sulphuric acid, a process known to early chemists for centuries. As a raw chemical it is dangerous: concentrated nitric acid burns skin, stains it yellow, and eats through many materials. The homeopathic remedy therefore has nothing in common with the chemical except its starting point. Through repeated dilution and vigorous shaking (succussion), nothing of the corrosive acid remains, while the healing imprint is retained.

Hahnemann and the prescribers who followed him found the remedy especially useful in chronic complaints that had been treated harshly, particularly the lingering effects of syphilis after mercury treatment, and in “scrofulous” conditions marked by swollen glands and skin eruptions.

Grauvogl described its “hydrogenoid” constitution, sensitive to cold, damp weather.
Key Indications
The best way to recognize whether Nitric Acid is your remedy is to look for its signature symptoms, which homeopaths call keynotes. When several appear together, the choice becomes clear.
Splinter-Like Pains
The keynote of Nitric Acid is pain as if a splinter or sharp needle were sticking into the part. The sensation can appear almost anywhere, but it is most typical in the throat (as if a sharp point were felt on swallowing), the tongue and soft palate, ulcers, the rectum during stool, and even the nose. The pains are sticking and stabbing, appearing and disappearing quickly rather than lingering.
Fissures and Cracks at Body Openings
Nitric Acid is one of the leading remedies for fissures, the painful little splits that form where skin meets mucous membrane. The classic example is an anal fissure: the stool is hard or difficult, the anus feels as if it is being torn during the passage, and the crack stays raw, sore, and slow to heal. The same tendency produces cracked corners of the mouth, cracked lips, sore nipples in nursing mothers, and fissures of the fingertips. The parts feel sensitive and bleed easily, and the person dreads the next bowel movement.
Offensive Discharges
Almost every discharge of the Nitric Acid patient is offensive. The urine smells strong, like horse urine, and may be scanty and dark, with burning and stinging on passing. The stools are slimy and foul. The sweat is offensive too, especially the foot sweat, which is so strong it makes the toes sore, and the armpits sweat offensively at night. In women, the leucorrhea is brownish, flesh-colored, watery, or stringy. In the nose, chronic catarrh produces a yellow, corrosive discharge.
Warts and Skin Growths
Nitric Acid has a marked action on warts, and the description is very specific: the warts are large, jagged, and uneven, like a piece of cauliflower, and they bleed on washing. They are often found on the hands, fingers, and genitals, and tend to be sensitive and sore. The remedy is also known for ulcers that bleed easily, have zigzag, irregular edges, and a base that looks like raw flesh. People with black pores on the face, or pimples worse on the forehead, may also benefit.
Mouth and Gum Complaints
The mouth is a key area for Nitric Acid: there are painful ulcers on the tongue and inside the cheeks and soft palate, and they sting as if splinters were sticking into them. The gums become soft, spongy, and bleed easily, and the teeth feel loose. The breath is putrid, there may be salivation, and in some cases the saliva is bloody. A useful detail from the provings: the tongue is often clean, red, and wet, with a furrow down the center.
Digestive Complaints and Diarrhea
On the digestive side, Nitric Acid covers two opposite pictures. One is constipation with great straining: the person strains hard and passes little, the rectum feels torn, and there are fissures and piles that bleed easily. The other is diarrhea that is slimy and very offensive, often in someone who catches cold easily. After a stool, the person may feel exhausted, irritable, and sore, with tearing pains that last for hours. There may also be a craving for fat and salt, and sometimes a strange longing for indigestible things such as chalk or earth.
Constitution and Personality Profile
The Nitric Acid patient has a mental and emotional picture as sharp as the physical pains. The person is irritable, easily angered, and at times hateful, vindictive, and headstrong. There can be a deep hopeless despair, and a real fear of death, especially at night.
A very characteristic feature is that sympathy makes them worse. When a Nitric Acid person is suffering and someone tries to console them, it aggravates them; they become more irritable and want to be left alone. This is the reverse of remedies like Pulsatilla, which craves consolation.
Physically, the typical Nitric Acid patient is past middle life, often dark-haired and dark-complexioned, with a tendency to catch cold easily and have loose bowels. There is an excessive physical irritability, an oversensitivity of the whole nervous system, and a history of chronic complaints that were suppressed or harshly treated.
Modalities
Homeopaths call the things that make symptoms better or worse “modalities,” and they are among the most reliable guides to choosing a remedy.
Worse from: cold, especially cold climate and cold air; evening and night, when most symptoms flare up; touch and jarring; noise, which can be almost unbearable; pressure, such as a hat causing headache; and, oddly, hot weather also aggravates some patients.
Better from: riding in a carriage or a car, one of the strongest and most famous modalities of this remedy. Almost all symptoms are better while riding, so marked that Boericke lists it as the remedy’s great distinguishing feature (the reverse of Cocculus, which is made sick by riding). Warmth is also generally helpful, as is gentle motion.
Dosage and Potencies
Homeopathic remedies are available in different potencies, reflecting how many times the original substance has been diluted and shaken. For Nitric Acid, three potencies cover most situations:
- 6C is a lower, gentler potency, well suited to local complaints such as mouth ulcers, warts, or fissures, and to first-aid-style use. It can be repeated more freely, up to two or three times a day for a short period, but should be stopped as soon as improvement begins.
- 30C is the most common potency for self-care. It suits the full picture of the remedy, including the mental symptoms, and is a good starting point for conditions that have been building up for a while. A typical approach is one dose of three pellets once or twice a day for a few days, then only as needed.
- 200C is a higher potency, best reserved for deep, long-standing constitutional complaints, usually as a single dose left to work for several weeks. It is not for repeated daily use without professional guidance.
The pellets are taken on a clean palate: allow them to dissolve under the tongue, away from meals, and avoid strong flavors such as coffee, mint, camphor, and spices for at least fifteen minutes before and after. Boericke notes that the sixth potency is the classic prescription, and that as the patient improves, skin symptoms may appear for a time, which is considered a favorable sign. For chronic or recurring conditions, consult a qualified homeopath.
Differentiation from Similar Remedies
Several remedies share pieces of the Nitric Acid picture, and knowing the differences separates a good guess from a good prescription.
Nitric Acid vs. Mercurius
Mercurius and Nitric Acid both cover offensive discharges, mouth ulcers, salivation, and a history of syphilis or mercury abuse. The differences are telling. Mercurius has profuse, soaking salivation day and night, a swollen tongue marked with the imprints of the teeth, and sweat that pours out without relief; the patient is worse at night, feels the cold of the bed, and tends to be hurried and weak. Nitric Acid’s mouth ulcers sting as if splinters were in them, the salivation is less overwhelming, and the patient is markedly better from riding in a carriage, a modality Mercurius does not share. Splinter-like sticking pains point to Nitric Acid; a metallic taste, heavy salivation, and trembling point to Mercurius.
Nitric Acid vs. Hepar Sulphuris
Hepar Sulphuris is the other great “splinter-like pain” remedy, so the two are often confused. The difference lies in the surrounding picture. Hepar patients are intensely chilly: a draft of cold air on a small part of the body is enough to make them shiver, they want warm covering, and their complaints tend toward suppuration, with offensive abscesses and pus. They are oversensitive to pain and fly into a rage over trifles. Nitric Acid patients are better from warmth too, but they are not as overwhelmingly chilly, and the keynote of relief from riding in a carriage is unique to Nitric Acid.
Nitric Acid vs. Thuja
Thuja is the great sycotic (warty) remedy, and it shares with Nitric Acid a tendency to warts, offensive discharges, and sensitivity to damp. But the warts differ in appearance: Thuja’s are soft, fleshy, and pedunculated, growing on stalks, often on the genitals and face, while Nitric Acid’s are large, jagged, horny, and bleed on washing. Mentally, the two are very different. Thuja patients have fixed ideas, feel as if a foreign body were under the skin, and tend to be secretive and brooding. Nitric Acid patients are openly irritable, angry, and vindictive, and despair of ever recovering.
Nitric Acid vs. Silicea
Silicea also has splinter-like pains and is a classic remedy for fistulas, fissures, and offensive foot sweat, so the comparison matters. Silicea patients, however, are mild, yielding, anxious, and easily exhausted, with low stamina and a chilly constitution that craves warmth; they take cold easily, heal slowly, and their complaints often involve pus that will not come to a head. Nitric Acid patients are the opposite in temperament: angry, irritable, and headstrong rather than gentle, and their key modality is relief from riding, which is not a Silicea feature. The mild, chilly, yielding type fits Silicea; the sharp-tongued, easily angered patient who is better on a drive fits Nitric Acid.
Safety Notes
It cannot be said too plainly: concentrated nitric acid is a corrosive chemical that burns the skin, eyes, and digestive tract, and must never be ingested or handled carelessly. The homeopathic remedy Nitric Acid is an entirely different thing. Through potentization, the acid is diluted to the point where no corrosive chemical remains; a 6C preparation, for example, contains far less than one molecule of the original acid per dose. The remedy is safe to take as directed and is sold as tiny sugar-based pellets.
That said, sensible precautions apply. Do not take the remedy with food in the mouth, and avoid strong flavors around the dose. Stop the remedy once symptoms improve; taking more than needed does not work faster. Keep pellets out of reach of children and store them away from strong-smelling substances. Pregnant women, nursing mothers, and anyone on regular medication should check with a doctor or qualified homeopath before self-prescribing.
Nitric Acid is not a substitute for medical care in serious situations. See a doctor promptly if you have bleeding from the rectum, a fissure that does not heal within a few weeks, unexplained weight loss, persistent fever, severe pain, or any lump, wart, or ulcer that changes in appearance.
Frequently Asked Questions
What is Nitric Acid 30C used for?
Nitric Acid 30C is most often used for the remedy’s classic picture: splinter-like pains, painful fissures (especially anal fissures), offensive discharges, mouth ulcers, and warts that bleed on washing. It also fits people who are irritable and worse from sympathy. If several of these match, 30C is a sensible potency to start with.
Is it safe to take Nitric Acid if the acid itself is corrosive?
Yes. The potentized remedy contains no corrosive acid. Homeopathic preparation dilutes the substance far beyond the point where any chemical remains, so the pellets are safe when taken as directed. The chemical and the remedy share only a name and an origin.
How do I take the pellets?
Take three pellets at a time, letting them dissolve under the tongue on a clean palate, fifteen minutes away from food, drink, or strong flavors like coffee and mint. For an acute flare-up, a dose once or twice a day for a few days is typical; stop as soon as you notice improvement.
Can Nitric Acid help with anal fissures?
It is one of the most frequently indicated remedies for them, particularly when the stool feels as if the rectum were being torn, the fissure is raw and slow to heal, and the person dreads passing stool because of the sharp, tearing pain. If there is any significant rectal bleeding, have it checked by a doctor first.
Which potency should I choose?
For local complaints and gentle self-care, 6C is a good start. For the fuller picture, including mood symptoms, 30C is the usual choice. 200C is best kept for deep, long-standing conditions, usually as a single dose under a homeopath’s guidance.
How long does it take to work?
Acute complaints such as a painful fissure or mouth ulcer may improve within hours to a few days of the right remedy. Chronic conditions take longer and may need a constitutional prescription from a professional.
