Botanical name: 

The inner bark of the Fraxinus Acuminata, or White-Ash, is tonic and astringent in small doses; if taken freely, it is actively purgative. We think it decidedly alterative. It has been used as a tonic in intermittents, and also as an astringent in hemorrhages. We have used the White Ash bark with benefit in dyspepsia, general debility and cachectic habits, with a view to its tonic and sustaining powers, and for its aperient action.

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