 this enzyme may be eliminated from the official as well as other kinos by a judicious method of collection, and considers it probable that the following one, adopted by J. Q. F. Marshall and described in the "Agricultural Ledger" (1900, No. 11, 381), will accomplish this: "A longitudinal cut is made with an axe or knife, called acha katti, through the bark of the trees, down to the cambium, about 1 ½ feet long, and side outs are made to lead into this. A bamboo tube is then fixed at the bottom of the main incision in order to catch the juice. In the course of about twenty-four hours the flow of gum ceases and the bamboo is taken down. When several of these bamboo cups are nearly full they are taken to headquarters and emptied into a large cauldron and the juice boiled. During the boiling, the impurities, consisting of pieces of bark, wood and leaves, rise to the surface and are skimmed off. When sufficiently concentrated to the consistence of a thick extract it is exposed to the sun, in thin layers, in shallow vessels until it is dry enough to crumble to pieces. The kino is then weighed and packed away in wooden cases." (P. J., 1903, 702.)
Botany or Blue Mountain kino is obtained from Angophora lanceolata Cav. Colombo kino is obtained from a number of species of Angophora. Hooper (P. J., 1908, xxvii, 161) reports the occurrence of three new astringent plant juices or kinos. They are derived from Jatropha Curcas, from South Salem; Xylia dolabriformis, from Burma; and Parkia insignis ("Myauk-ta-nyet"), also from Burma.
Uses.—Kino is powerfully astringent, and in this country is much used for the suppression of morbid discharges. In diarrhea, not attended with febrile excitement or inflammation, it is often an excellent adjunct to opium and the absorbent medicines, and is a favorite addition to chalk mixture. It is also used in chronic dysentery when astringents are admissible; in leucorrhea and diabetes; and in passive hemorrhages, particularly those from the uterus and the intestines. The infusion may be made by pouring eight fluidounces of boiling water on two drachms of the extract, and straining when cool; aromatics may be added, if deemed advisable. The dose of this infusion is a fluidounce (30 mils). The proportion of alcohol in the tincture renders it frequently an unsuitable preparation.
Dose, eight to thirty grains (0.5-2.0 Gm.).
