Celastrus paniculata, Willd. (C. alnifolia, DC.; C. Rothiana, Roem.; Diosma serrata, Blanco.)

Nom. Vulg.—Bilogo, Tag.

Uses.—I am not acquainted with the medicinal uses of this plant in the Philippines. In India, by means of a primitive system of distillation, they extract from the seeds a dark-colored oil of empyreumatic odor, which under the name of Oleum nigrum was once proclaimed by Dr. Herklots as the sovereign remedy for beriberi.

This oil in doses of 10–15 drops a day is a very powerful stimulant, the action of which is manifested by profuse perspiration several hours after its administration. Malcolmson reports that it has given him good results in several cases of beriberi, particularly in recent cases and those in which nervous and paralytic symptoms predominated. In Concan, the juice of the leaves is given in doses of 30 grams as an antidote for opium. The bruised seeds made into a paste with cow urine are used locally in treatment of itch. They are also used in the treatment of leprosy, gout, rheumatism, and other diseases which according to their medical theories, are derived from “cold humors.” For these purposes they give the seeds internally, beginning with one and increasing daily until 50 are taken. At the same time they make external applications of the oil or of another compound prepared in the following way:

Place in an open pot with one opening, seeds of C. paniculata, cloves, benzoin, nutmeg and mace. The pot having been previously heated, is covered with another, inverted over the opening. On the sides of the latter a thick black oil condenses which Herklots very appropriately named Oleum nigrum.
