Botanical name: 

Mezereum, described under the class of Alteratives, is a stimulating diaphoretic, and has afforded much benefit in the treatment of cutaneous diseases and chronic rheumatism. It is rarely employed with a view to the production of free perspiration or sweating, but for the purpose of augmenting the insensible transpiration, for which it is esteemed valuable in the treatment of many chronic affections.

The American Eclectic Materia Medica and Therapeutics, 1898, was written by John M. Scudder, M.D.
