Birthwort Family.
Aristolochia Indica, L.
Nom. Vulg.—Timbag̃an, Malaubi, Tag.; Indian Birthwort, Eng.
Uses.—The root has a wide use in medicine in the Philippines; it is bitter, of a nauseating odor and has the reputation of being a powerful antidote for the bites of poisonous serpents and insects. It has further use in the treatment of malarial fever, in dyspepsia, and in the flatulent colic of teething children. It is regarded as tonic and emmenagogue. In various forms of diarrhœa it appears to be effective and Dr. Gibson states that it is useful in intestinal disorders. In the Philippines it is not only given internally but also externally applied over the abdomen, mixed with hot cocoanut oil (10 grams of the powdered root to 100 oil).
The first Portuguese settlers in India called the drug “Cobra Root,” because the natives regarded it as an antidote for the bite of the terrible “Cobra da Capello.” This reputation, however, seems not to have been deserved, judging from the fearful mortality in India and Ceylon due to the bite of the cobra.
Dr. Imlach, a surgeon of Singapore, states that in one season in one collectorate, Shikapore, no less than 306 cases of snake bites were officially reported, the mortality being 63, or about 20.58 per cent. Other reports make it safe to conclude that in the entire province during the year no less than 300 deaths were due to this cause alone. Dr. Waring believes that if an antidote for snake bite exist in the vegetable kingdom it will most probably be found in the natural order Aristolochiaceæ.
In North India this drug is used as emmenagogue and anti-arthritic, and in Banda for intermittent fevers and intestinal disorders. The juice of the leaves is emetic. The dose of the powdered root is 3–5 grams daily.
