Vulg.--_Cañafistula_, Sp.; _Lombayong_, _Ibabaw_, _Baloyong_, Vis.; _Purging Cassia_, Eng. Uses.--The pod known in pharmacy under the name of "Cañafistula" contains a blackish, sweet pulp, which is a mild purgative if combined with carminatives, but it produces severe colic if given alone. The urine sometimes takes on a dark color after taking it. The laxative dose is 4-8 grams, the purgative 30-60. Extract of Cassia.-- Pulp and seeds of ripe pods 1 kilo. Water 1 liter. After mixing the pulp with water the liquid is strained through a woolen cloth; the material which remains in the strainer is washed with a little more cold water which is added to the other liquid and the two are evaporated to the consistency of the extract. Dose.--15-30 grams. Dr. Irving states that the root is a very energetic purgative. In Concan the juice of the tender leaves is used in the treatment of impetigo.
