Galls. Excrescences or tumours caused by the punctures and deposited ova of a hymenopterous insect (Diplolepis Gallse TinctoriAe) on the twigs of Quercus In-fectoria, the Gall Oak. Nat. Ord. CupuliferAe. Linn. Syst. Moncia Polyandria. Source, Asia Minor and Persia.
Med. Prop. and Action. Astringent. Their astringency depends upon the presence of Tannic and Gallic acids; of the former they contain 36, of the latter 5 per cent. They have, for many centuries, been held in high esteem in the East, in dysentery and ague. They are used as an antidote in poisoning by Ipecacuanha, Emetine, the alkaloids generally, and those vegetable productions whose activity depends upon an alkaloid, as Opium, Aconite, &c. They are also said to be an antidote in poisoning by Tartar Emetic, but this appears doubtful. (Pereira ) They may be given in infusion (oz. ss., Aq. Ferv. fl. oz. vj.). Externally they are used in the form of ointment.
Offic. Prep. 1. Gallic Acid. (See Gallic Acid.)

In Diarrhoea unattended by inflammation, Galls may occasionally be given with advantage. Prof. Royle * states that he has frequently given powdered Galls, in doses of gr. x. - xx., several times a day, in the obstinate diarrhoeas of the natives of India.
Roots states that he has given the infusion of Galls, in combination with Opium, with the most marked benefit. Its nauseous taste is a great objection to its use.
Walker, of the Lock Hospital, found great benefit from Pulv. GallAe, in doses of gr. x. - xx., in decoction of Tormentilla daily. In Chronic Gonorrhoea and Gleet, the internal use of Galls (gr. xx. - gr. xxx. daily) has often a marked effect in checking the discharge.
1294. In Atonic Menorrhagia, an infusion of Galls, daily injected into the vagina, warm or cold, according to the feelings of the patient, is occasionally of great service.
1295. In Prolapsus Uteri vel Recti, the daily use of an enema of infusion of Galls proves serviceable in astringing the parts.
1296. In HAemorrhoids, one of the most popular and efficacious external applications is Ung. GallAe, to which a portion of finely-powdered Opium should be added. The Confect. Pip. Nig. may be advantageously given internally, at the same time.
They were favourably spoken of by Poupart, but experience has proved them to have very slight febrifuge power.
