Botanical name: 

The roots and leaves of the Flowering Raspberry, described in the class Astringents, are said to exercise a specific influence over the secretory functions of the kidneys. They have been found beneficial in suppression of urine, gravel, and in cases of chronic irritation or inflammation of the urinary organs, attended with a mucous or purulent discharge. It may be classed with the tonic and astringent diuretics. It is exhibited in the form of a decoction, which may be taken freely.
