Raspberry Leaf - Feed Ingredient

Raspberry leaf, derived from the plant Rubus idaeus, is a botanical ingredient used in some equine feed and supplement formulations. It is typically harvested from the leaves of the red raspberry plant and dried for use. Raspberry leaf has a long history of use in herbal medicine, particularly for its astringent and uterine-toning properties, and is commonly included in herbal blends for mares.

In equine applications, raspberry leaf is used primarily for its purported effects on the reproductive system, especially in mares. It may be included in supplements intended to support a normal heat cycle or to help maintain comfort and demeanor during estrus. The active constituents include tannins, flavonoids, and fragarine, a compound thought to influence smooth muscle tone. While its use is largely based on traditional knowledge and anecdotal evidence, it remains a popular choice in herbal equine formulations.
