cortex phellodendri

Cortex Phellodendri, known as Huang Bai in Traditional Chinese Medicine, is the dried bark of Phellodendron chinense Schneid. or Phellodendron amurense Rupr. It is widely utilized for its anti-inflammatory, antimicrobial, and wound-healing properties, which are primarily attributed to its rich content of isoquinoline alkaloids, including berberine, palmatine, and phellodendrine. These compounds inhibit the activation of the NF-kappaB signaling pathway and reduce the expression of pro-inflammatory cytokines such as TNF-alpha and IL-6. In clinical practice, Cortex Phellodendri is often a primary component of topical formulations, such as the Compound Huangbai Liquid Topical Solution, which is used to treat skin and soft tissue infections, pustular sores, and various postoperative or chronic wounds, including diabetic foot ulcers. Recent clinical evaluations, such as those conducted by Guangzhou Eighth People's Hospital, focus on its ability to manage wound exudation and promote tissue regeneration in adult patients with infectious or postoperative wound conditions.
