Introduction
Angelica dahurica (Bai Zhi) is effective in treating skin disorders. It contains photoreactive compounds—such as bergapten, xanthotoxin, and isoimperatorin—furanocoumarins that are clinically useful in the treatment of vitiligo. Additionally, Angelica dahurica helps suppress the development of dermatitis. Its aqueous decoction exhibits inhibitory effects against various pathogenic bacteria *in vitro* and can improve microcirculation, thereby promoting skin metabolism.

Angelica dahurica, known in traditional Chinese medicine (TCM) as “Baizhi,” is a tall, perennial herb reaching heights of 1–2.5 meters. It features cylindrical roots, a stem base measuring 2–5 cm in diameter, basal leaves that are once-pinnately compound, terminal or lateral compound umbels, and oblong to ovoid fruits. Can Baizhi help treat skin conditions?

Can Baizhi Help Treat Skin Conditions?

Yes, Baizhi can aid in treating various skin disorders. For instance, it contains photoreactive compounds—such as bergapten, xanthotoxin, and isoimperatorin—classified as furanocoumarins, which are effective in managing vitiligo. Baizhi also helps suppress the development of dermatitis. Its aqueous decoction demonstrates inhibitory effects against multiple pathogenic bacteria in vitro, improves microcirculation, promotes skin metabolism, and delays skin aging.

Modern medical research has revealed that Baizhi possesses arterial vasodilatory properties. When applied topically, it dilates facial blood vessels and enhances local blood and qi circulation, thereby naturally improving facial complexion—making the skin appear more hydrated and lustrous. However, Baizhi is considered warm in nature; thus, individuals with yin deficiency and blood-heat patterns should avoid its use. This includes patients presenting with rashes, abscesses, or other manifestations of blood-heat, who may require combination therapy with other herbs.

The Shennong Ben Cao Jing (Divine Farmer’s Materia Medica) states that Baizhi “nourishes the skin and enhances its luster.” The Ri Hua Zi Ben Cao (Materia Medica of the Rihua Master) notes its analgesic and tissue-regenerating properties, as well as its ability to remove facial pigmentation spots. Ancient cosmetic formulas utilizing Baizhi continue to inspire modern dermatological applications. We hope this response proves helpful to you!
