Ginseng is a plant characterized by a fleshy root and a single stalk with green oval-shaped leaves. It is a perennial plant that can live more than a century. Ginseng extract is typically derived from the root of this plant. As a herbal supplement, the extract has long been prized for its reputation of having anti-inflammatory, anti-cancer, and antioxidant properties. It is also used in the homeopathic treatment of conditions, including depression, stress, low libido, and attention deficit hyperactivity disorder (ADHD).
