The only reason I would take up jogging is so that I could hear heavy breathing again.
Picric Acid. Picronitric acid. Carbazotic acid. Trinitrophenol.
SUBSTANCE Pale yellow, odourless, intensely bitter crystals, melting at 122o C and exploding above 300o C. One gram dissolves in 78 ml water and in 15 ml boiling water. Incompatible with oxidizable substances, albumin, gelatine, concrete, plaster, ammonia, alkaloids, and metals [particularly copper, lead, mercury, and zinc]. When picric acid is less than 30% solution in water or it is not hydrated it is extremely shock sensitive and will explode on movement. Because picric acid is very sensitive to heat, it has to be kept in a cool place. It explodes when rapidly heated. [Picric acid is a close relative of trinitrotoluene, or TNT, the high explosive.]
USES Used in the manufacture of explosives, matches, and coloured glass; in the leather industry; in electric batteries; for etching copper; as a textile mordant; as a reagent. At the beginning of the 20th century it was employed as a dressing for burns, but its use was abandoned because its absorption through skin and wound surfaces resulted in renal damage.
TOXICOLOGY Ingestion of 1 or 2 grams of picric acid in man causes severe poisoning, resulting in blood abnormalities and liver and kidney damage. Ingestion of small amounts causes gastrointestinal irritation with nausea, vomiting and diarrhoea; vertigo and headache; tremors and convulsions. In addition, it may cause acute hepatitis and unconsciousness. Prolonged or repeated skin contact may cause local or generalized allergic reactions, and possible destruction or ulceration. Prolonged or repeated exposure results in yellow staining of the skin and conjunctiva and ‘yellow vision’.
PROVINGS ••  Couch – 7 [male] provers, c. 1874; method: single or repeated doses of 30c, 25c, 15c, 10c, 5c, or 2c, or 1c, for periods ranging from 3-14 days.
••  Jones – 5 provers [4 males, 1 female], c. 1878; method: repeated and/or increasing daily doses of 1x or 2x for periods ranging from 9-14 days.
••  T.F. Allen – 2 provers [1 male, 1 female]; method: repeated doses of 30c.
The female prover in Allen’s proving – an unmarried woman aged 26 – produced the symptom “While enjoying the society of gentlemen, the idea of marriage seemed unendurable.”

One prover, who had been taking 10 to 40-drop doses of 1x dil. generally four times a day for 16 days, noticed on the 16th day “a peculiar nervous symptom which I never have, except when a fever is leaving me. I felt as if I was about to be crushed by the bedclothes; arms, face, tongue, and forepart of brain seemed to reach to the clouds when I was going to sleep.” [Allen]
Sankaran presents a highly inventive reading of the latter delusion:
• “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 of Picricum acidum is: ‘I feel that my intellectual capacity and organs used to express it are stretched far beyond their limits. So now I need to rest and bring them back to health.’ … 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.” [Sankaran]

G < PHYSICAL EXERTION. G INTENSE SEXUAL EXCITEMENT. [Occurred in 6 male provers.] • “Awoke in the night with violent erections, which cold water relieved; returned to bed, and before an hour had elapsed, was again awakened by violent erections, applied cold water, and slept the remainder of the night [I will here remark that I had been suffering for several months with loss of sexual vigour and entire absence of venereal desire, not having had any erections for several months, but now it is the reverse, altogether too much of a good thing].” • “For two weeks following, the drug caused marked increase of sexual desire. After a second dose, most remarkable and intense sexual excitement, which is not allowed to be gratified by any indulgence. Amorous excitement, impelling the mind to dwell on and revel in imaginary sexual pleasure. Almost constant priapism, night and day, for seven days, impelling to amorous ecstasies and mental analysis of the physiological and psychological aspect of venery.” [Allen] P Headache from mental exertion in school children. And DILATED PUPILS. P Headaches of students, teachers, professionals and overworked businessmen • “Headaches ‘up to bursting’ begin in the occiput and extend forward to the eyes; they are relieved by tightly binding the head and are worse from movement, from any effort, from dazzling light, from summer heat, in warm rooms, better in the fresh air and lying down.” [Leeser] P Headache.
