Habitat: It is a native of Malacca, Sumatra, Cochin-China, and other parts of Eastern Asia, and is largely cultivated in the islands of Bintang, Singapore, and Prince of Wales.
Description;This is a climbing shrub with slender stems somewhat thickened at the nodes; leaves ovate or oblong, entire, rounded at the base but abruptly attenuated at the summit, opposite and stipulated, smooth on both sides.

The stem is woody, often angular; leaves oblong-ovate, 7.5-10 Cm. (3-4′) long, petiolate, acuminate, entire, smooth; flowers small, pinkish, in clusters, calyx and corolla 5-divided, stamens 5, ovary 2-celled; fruit 2.5 Cm. (1′) long, narrow, ovoid tapering at each end, dehiscent, pericarp dry; seeds numerous, minute, pale brown, rough, tailed at each end.
The flowers are small, crowded into a dense globular head on a hairy receptacle; the flower heads are borne on long axillary peduncles which bear in the middle a whorl of bracts. At the point where these bracts occur the peduncle breaks after the falling of the inflorescence and the remainder of the peduncle becomes elongated and curved into hooks by means of which the plant climbs. Corolla gamopetalous, trumpet-shaped, tube slender; fruit one inch long, pericarp dry, dehiscing vertically into two valves; seeds very numerous.
The gambir is prepared by lopping off the leaves, shoots, and twigs of the plant, chopping them into pieces, and throwing them into an iron pot filled with boiling water. When the leaves are exhausted and the liquid sufficiently thick, it is poured into small wooden tubs, and so soon as sufficiently cool, a half-closed hand is plunged into the semi-fluid mass and a piece of light wood shaped like an elongated dice box rapidly worked up and down in the hollow formed by the hand. The extract begins to thicken by a process which is compared to crystallization. The mass is finally turned out, and cut into cubes, which are put upon trays and smoke-dried. This extract, which is known by the native Malays as pinang or siren was first brought to the attention of the profession by Campbell.
Enormous quantities of gambir are used both in Europe and America in tanning, calico printing, dyeing, as an ingredient in boiler compounds for preventing the hard scaly incrustation caused by certain kinds of water, and other art processes requiring tannic acid.
Vanderkleed and E’we call attention to the fact that the apparent alcohol soluble content of gambir may be unduly raised by the high moisture content of some of the commercial varieties, which they report as containing over 21 per cent. of moisture, all of which would be calculated in the alcohol soluble extractive by the ordinary methods in which no allowance is made for water.

Medical Action & Uses:
Gambir is a serviceable remedy in those cases where astringents are indicated.
The complaints to which it is best adapted are diarrhea dependent on debility or relaxation of the intestinal mucous membrane, and passive hemorrhages, particularly from the uterus. A small piece held in the mouth and allowed slowly to dissolve is an excellent remedy in relaxation of the uvula and the irritation of the fauces and troublesome cough which depend upon it. Applied to spongy gums, in the state of powder, it sometimes proves useful; and it has been recommended as a dentifrice in combination with powdered charcoal, Peruvian bark, myrrh, etc.
Uses. – Diarrhoea, leuchorrhoea, gonorrhoea, cough, chronic sore throat, phthisis, bronchitis, hemorrhages, relaxed uvula, ulcerated nipples, chronic ulcers, relaxed oral mucous membrane and spongy gums (mouth-wash). In the arts for tanning, dyeing.
Dose, from ten grains to half a drachm (0.65—2.0 Gm.), which should be frequently repeated, and is best given with sugar, gum arable, and water.
