NOM. VULG.—Cañafistula, Sp.; Lombayog̃, Ibabaw, Baloyog̃, 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.
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.
