Guarea Rusbyi

COCILLANA (Syn. Guarea, Guapi Bark) Guareae Cortex is the bark of Guarea rusbyi (Britt.), Rushy and closely related species, family Meliaceae. It is obtained mainly from Bolivia. Cocillana is a more stimulating expectorant than Ipecacuanha. The unidentified alkaloid fraction contributes most probably to the expectorant effect.

Trees native to the South American Andes. Part used is the dried bark. The original cocillana bark is believed to be derived from G. rusbyi. However, there is evidence that the current drug is obtained from other closely related Guarea species and is not the same as the cocillana first introduced into modem medicine (usd 23rd). The bark is collected in Haiti and Bolivia (evans).
