[R. Sankaran]

Remedy of the mineral kingdom. The main theme of an acid is struggle followed by collapse; exertion and exhaustion. The struggle is constant. It is an effort that, the person feels, has to be made in a particular direction. At some point in this constant struggle, the patient is so exhausted that a small setback like the proverbial straw that broke the camel’s back, leads to a state of collapse.

In Picricum acidum we see a tremendous effort in the direction of intellectual achievement. The main are: “Delusion, arms reach the cloud when going to sleep”, “Delusion, tongue seems to reach the clouds when going to sleep” and in the original proving we have “Forehead seems to extend towards the clouds”.

What do these delusions represent?

The forehead is for thinking, the hand is for writing and the tongue is for speaking. These are the three organs of intellectual activity and they feel stretched to the limit, extended right up to the clouds. Thus the main feeling in Picricum acidum is: “I feel that my intellectual capacity and organs used to express it are stretched far beyond their limits. So I now need to rest and bring them back to health.”

The situation of Picricum acidum is one where a man has extended his intellect beyond his limit, has used these organs beyond their limit so that they are stretched beyond the clouds and now he needs to shut up, cut off and take rest. To help him do this, he gets increased sexual thoughts; the opposite to the intellectual activity.

Thus in the failed state of Picricum acidum we see dullness, sluggishness, inability to think long, mental work becomes impossible. Such a state is reached usually in a person who had made a tremendous mental effort and is now exhausted – brain-fatigue. This may be seen, for example, in students preparing for highly competitive exams.

o Concentration difficult, studying, reading, etc., while.

o Dullness, think long, unable to.

o Lascivious.

o Prostration of mind, writing, after.

o Work, aversion to, mental.

Sexual.- In accordance with its influence on the sexual organs, picric acid is a remedy for sexual weakness with seminal emissions; for satyriasis; for spermatorrhoea with

the resulting impotence, and for sexual neurasthenia.

In the female system useful for prostration the result of too profuse menses and for vulvar pruritus preceding menses. It has cured warts on the genitals.


Efficacious in nephritis, chronic or subacute, with dragging-down pain in the region of the kidneys, dark, scanty urine and prostration. The dimness of sight and hardness

of hearing for which it is useful are those accompanying or the result of the brain fag and nervous prostration, which are the main sphere of action of the drug. It is useful

for ophthalmia > cold bathing and cold air, if part of a neurasthenia complex.


Skin.- Furunculosis (auditory meatus), in which it is specific. It is also good for pustular acne. Externally, a valuable application for burns of the 3th and 2nd degrees.

A saturated solution (picric acid 90 gr. to alcohol 3oz.) dissolved in 1 quart of water is applied to the burnt surface by means of strips of sterilized gauze soaked in it, and retained by a bandage to be removed after three days, and re-applied till healing takes place, which quickly occurs with little or no pain.
