Yohimbe bark, derived from an evergreen tree native to Central and Western Africa, has a long history in traditional medicine as a sexual performance enhancer and stimulant. Its active compound, yohimbine, is an alpha‑2 adrenergic receptor antagonist that may improve circulation, support libido, and aid fat metabolism. Modern supplements often market yohimbe for erectile dysfunction, athletic performance, and weight loss, though scientific evidence remains limited.
