Acid group of remedies in homoeopathy

Most of acids are colourless or light coloured
Corrosive in nature
Sour in taste
Mostly odorless but some having peculiar odour
Evaporates when heated
Combine easily with other elements to form compounds

The word acid comes from Latin , Acious- sour
An acid may be defined as a substance that can provide H+ ion, proton donor, or any substance that liberates hydrogen ion in a solution.
Most acids derive from mineral kingdom, few from vegetable eg: lactic acid


Used in manufacture of fertilizers, chemicals, explosives, bactericides
Waste water processing
Acids are dehydrating agents, so used in preparation of dry fruits

Classification of acids- mainly two types

Organic- weak or vegetable acids- slow, progressive action producing deep pathology
Inorganic- strong or mineral acids- rapid , acute action producing deep pathology
General characteristic features of acid group( farrington)

1) Acids produce weakness, debility & prostration

The mineral acids, as a class, all produce an irritability of fibre together with weakness and prostration. Whereas the vegetable acids produce weakness without irritability.

2) All the acids cause a peculiar debility.

This is not a simple functional weakness, such as might result from a rather exhausting diarrhoea, such as you find under CINCHONA, or such a functional weakness of the nerves as will be curable by ZINC, but it is a debility which arises from defective nutrition, particularly from blood disease.

Thus we find them called for in very low types of disease, disease in which blood poisoning is a prominent feature, in typhoid states and in scarlatina, particularly when of a low type.

In conditions of exhaustion from abuse of various organs of the body. Thus drunkards, who have long been indulging in liquors to excess, may be relieved by Sulphuric, Phosphoric and Arsenious acids.

3) The acids check haemorrhages- ACET AC, CITRIC AC, PHOS AC, ARS AC

4) Tendency to produce pseudomembranes. so some of them indicated in diphtheria- MURIATIC, PHOSPHORIC, SULPHURIC AND NITRIC ACIDS.

As these acids, particularly the vegetable acids, may cause croupous deposits, do not permit a child convalescing from croup to partake of acid fruits. When the child is susceptible, any one of these acids may tend to produce this disease again

5)Indicated in diabetes mellitus. The principal acids for this condition are PHOSPHORIC AND LACTIC ACIDS.

6) Many of the acids are useful in scurvy, particularly when it has arisen from a diet of salty food with deprivation of vegetables.

Constitution: Lean, thin, tubercular constitution with stooped shoulder and premature old look.

Thermal – Chilly- except fluoric acid & picric acid


Mineral acids- active bleeding
Organic acids—passive bleeding


Acids have all the miasms , but predominantly syphilitic
Inorganic acids- predominantly syphilitic
Organic acids- sycotic & tubercular

Sphere of action

I.mucous membranes–.inflammation; destructive ulceration.

II.glandular system.–congestion; inflamation.; fetid discharges., salivation– pustular ulceration; fungoid growths; perspiration.

IV blood. –broken-down, septic condition, anaemia, haemorrhage

V CEREBRO-SPINAL SYSTEM. Prostration, from Loss of Nutrition.

VI.DIGESTIVE ORGANS. Atony of the whole Apparatus.

VII BONES .Rachitis and Caries., syphilitic affections

1) They decrease the acid secretions in the body and increase the alkaline secretions of the body. For example; if a quantity of citric acid is taken into the stomach it will diminish the secretion of gastric juice. On other hand it will increase the secretion of saliva which is alkaline in nature.

2. Antidotal and complimentary action to certain drugs.
a) Vinegar retards the action of Belladonna, but lemonade aids the action of the remedy.
b) Antimonium crudum will not tolerate acids but you may use tamarind water.

3. Dyspepsia :
Vegetable acids are useful in dyspepsia.
Example; Allow the patient to drink lemonade before meals and we can find that the usual heart burn and sour rising after eating are diminished. Some persons are greatly relieved by drinking sour milk ( Lactic acid). Muriatic acid and Hydrocyanic acid favor digestion. Some persons have been cured of dyspepsia by eating peach kernels which contain these acids.

4. Antidote for intoxication.
Vinegar ( acetic acid) has been used as an antidote for intoxication.

5. Corrosive action:
Discharges are acrid and excoriating .
Example; Lactic acid: It will eat into every tissues of the body . It will dissolve enamel of teeth. Dr. Hering was in the habit of recommending that the teeth be washed occasionally with milk cream that had become sour by keeping 24 hours.

Common Mental Features

Basic themes of acid group

1) Exhaustion

The most common and well known characteristic of the Acids is exhaustion. Vithoulkas (1991 b, page 251) describes the mental exhaustion of Pic-ac, the emotional exhaustion of Ph-ac, and the physical exhaustion of Mur-ac.

Physiologically exhaustion is accompanied by an Acid imbalance.

2) Activeness, hurriedness

Prior to this exhaustion there will be the exact opposite, i.e. an overdose of activity. The Acidums want to do a lot. They exhaust themselves, they use their energy at a very high rate. They don’t necessarily have any complaints yet at this stage, they are merely overactive.

This gives us the next characteristic of the Acidums: hurriedness. This is well known in Sul-ac, one of the most hurried remedies, but the other Acidums have this trait as well. Hurriedness is a symptom that is often accompanied by tiredness or exhaustion, the primary symptom of the Acidums.

3) Lively, fresh, extrovert

The Acidums have a certain freshness about them, especially in the beginning,. They are extroverts and talk easily and openly. Allen writes about Ph-ac: ‘lively, vivacious mood’. Their sexual desire is high.

They have a tendency to be perfectionists, they have a great desire to have everything ‘just so’. This rather forced attitude often makes the opposite happen in their lives.

4) Aggression , fighting.

The overactivity goes together with a certain aggressiveness.

This aggressive side expresses itself physically in the rather biting, etching character of the complaints, as in aphthae, ulcers and fissures.

5)Desire for unification

Behind the aggression of the Acidums lies one very strong desire: that is the desire to become one with everything and everyone. This aspect comes out very clearly in pure hydrogen.

6) Isolation , apathy

But hydrogen also has the opposite feeling: a deep feeling of isolation, of being separated from your fellow beings and loved ones. Hydrogen has both a feeling of total unification and a sensation of total isolation. The Acidums have a similar theme, each one expressing it in their specific area. Ph-ac, for instance, has the desire for total communication, the way in which twins can often do this.
