Botanical name: 

The leaves of Vaccinum frondosum.

Therapeutic Action.—Vaccinum is diuretic, tonic and astringent. The leaves possess decided diuretic properties, and as such are used in dropsical affections, especially when accompanied with great debility. They, like the preceding article, are adapted to that class of urinary affections attended with chronic irritation or inflammation and a profuse mucous or purulent discharge; they are also recommended in calculous affections to relieve irritation.

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