Pterostilbene, a white or off-white crystalline powder, is an active ingredient derived from plants such as rosewood, blueberry, grape, and palmyra. Because it was first discovered in rosewood, it was named pterostilbene. Pterostilbene has extensive medicinal value and is an antifungal active ingredient in dragon's blood products. It has anticancer, anti-inflammatory, antioxidant, and analgesic properties. Numerous studies have shown that pterostilbene is effective in the treatment and prevention of skin diseases, particularly in the field of antioxidants. It is also effective in the treatment of cancer, hypertension, and hyperlipidemia. Recently, researchers have mastered the industrial synthesis of pterostilbene.
