Buckthorn Alcohol-Free Liquid Extract Organic Buckthorn Frangula Alnus Dried Bark Glycerite Herbal Supplement 2 oz

Buckthorn is a deciduous shrub, growing to 3–6 m, occasionally to 7 m tall. It is usually multistemmed, but rarely forms a small tree with a trunk diameter of up to 20 cm. The bark is dark blackish-brown, with bright lemon-yellow inner bark. The buckthorn is a shrub native to Europe, Western Asia, and the Middle East. Buckthorn is never used fresh. It is collected in the summer, and then must be aged for at least a year to break down its anthrone chemicals. Buckthorn contains 1,8-dihydroxy-anthracene derivatives (in the aged bark), flavonoids, and tannins.
