Gallic Acid. C7 H6 O5. Trituration.
Clinical.-Asthma. Constipation. Debility. Delirium. Haemorrhages. Phthisis. Urticaria.
Characteristics.-Gallic acid is the well-known astringent, derivative of Tannic acid, obtained from galls or oak-apples. It is used in old-school practice as a local application to arrest haemorrhages. A case is recorded (H. W., xxviii. 502) in which the application of an ointment containing Gallic acid, or the insertion of a tannin suppository for piles, caused an attack resembling hay-asthma, with an eruption of urticaria. The experience was repeated several times before the cause was found out. This is sufficient to show that Gall. ac. is truly homoeopathic to pulmonary cases, in which it has been largely used by the old school as well as the new. In pulmonary haemorrhage, and in the excessive expectoration and the night-sweats of phthisis it has been found of especial service. Marcy, of New York, has recorded the case of a young lady who had a cavity in the left lung, with copious purulent expectoration, night-sweats, evening fever, pulse 130. Under the prolonged use of Gall. ac. 1x she recovered her normal health except that the left lung remained dull and she had great shortness of breath on the slightest exertion. Her flesh, strength, and general appearance were as when she was in perfect health. Bayles says it rapidly cheeks secretions, gives general tone to the stomach, increases appetite and removes constipation. This last must be a homoeopathic effect. Gall. ac. is used in popular practice to check excessive menstruation. Prominent symptoms in the proving are: Weakness with irritability. Excessive dryness of mouth and throat. Sense of contraction of anus. Jerking of limbs. Itching of skin.
