Gamboge Family.

Garcinia mangostana, L.

Nom. Vulg.—Mangostán, Sp.; Mangosteen, Eng.

Uses.—The seed of the fruit is astringent and is given internally as an infusion in dysentery and chronic diarrhœa. The decoction is very useful as an injection in leucorrhœa.

The following potion has given excellent results to Dr. Ed. J. Waring in chronic dysentery and the diarrhœas of tropical countries:

Dried peel of mangosteen 60 grams.
Cumin seed 5 grams.
Coriander 5 grams.
Water 1,200 grams.

Boil till reduced to 600 grams. Take 120 grams twice a day. Tincture of opium may be added.

An analysis of mangosteen peel by W. Schmidt demonstrated a large quantity of tannin, a resin and a crystallizable principle named mangostin (C20H23O5) which exists in the form of fine, golden yellow laminæ, tasteless, soluble in alcohol, ether and the alkalies, insoluble in water. With the perchloride of iron it gives a blackish-green color, and sulphuric acid colors it red.

Botanical Description.—The mangosteen grows only in the southern islands of the Archipelago and its delicious fruit is the part of the plant known in Manila. The peel is at the present time almost universally employed in medicine. The fruit is about the size of a small Manila orange, the pericarp a dark red or chocolate color, tough and thick, crowned with the remains of the calyx. On breaking it open the edible portion of the fruit is seen, consisting of 6–18 seeds covered by a white, sweet pulp, cottony in appearance, of a delicious slightly acrid flavor.
