Hoang-nan. Strychnos malaccensis.
Hoang-Nan.—This is the bark of Strychnos malaccensis Benth. (Fam. Loganiaceae), a climbing plant, which grows in Malacca and surrounding countries. Brucine and strychnine are stated to have been found in it, brucine being the more abundant of the two. It has been found to produce in animals general tetanic spasms similar to those caused by strychnine. It probably has the same range of medicinal application as has nux vomica, although special virtues have been claimed for it in the treatment of chronic skin diseases. Dose of powdered bark, three grains (0.2 Gm.).
