Phellodendron amurense, commonly known as Amur cork tree, has a long history of use in traditional Chinese medicine (TCM). In TCM, the bark (known as "Huang Bai") is believed to have cooling properties and is used to "clear heat" and "dry dampness," which sometimes includes treating conditions involving swelling and inflammation, possibly including swollen lymph glands. However, its traditional use is more often associated with urinary tract infections, diarrhea, and skin diseases rather than specifically for lymphatic gland swelling. There is very limited scientific research examining the effects of Phellodendron amurense on swollen lymph glands or lymphatic health in general. Most available studies focus on its anti-inflammatory, antimicrobial, and anticancer properties, attributed to compounds such as berberine and palmatine. These compounds may have general immune-modulating and anti-inflammatory actions, but there is no direct clinical evidence demonstrating effectiveness in treating swollen lymph nodes in humans. In summary, while there is some traditional basis for using Phellodendron amurense in conditions that might overlap with swollen glands (due to its anti-inflammatory reputation), scientific validation for this specific use is lacking. Evidence supporting its use for swollen lymph glands is weak and based primarily on broader traditional applications and some indirect anti-inflammatory effects observed in laboratory studies.
