Pterocarya fraxinifolia
A Caucasian riparian tree with folk medicinal bark uses for skin conditions and as an astringent.
Pterocarya fraxinifolia, the Caucasian wingnut, is a riparian tree whose bark has traditional use as an astringent for skin conditions. Its primary active compounds include tannins, flavonoids, and trace amounts of juglone, which contribute to its limited modern research profile. Evidence for its efficacy remains at level C, with most data derived from traditional use and preliminary phytochemical studies.
The astringent action is primarily due to tannins, which precipitate proteins and form a protective layer on mucous membranes and skin, reducing inflammation and exudation. Flavonoids provide antioxidant effects by scavenging free radicals and inhibiting pro-inflammatory enzymes such as cyclooxygenase and lipoxygenase. Juglone, though present in trace amounts, may exert antimicrobial activity by inhibiting bacterial DNA gyrase and topoisomerase IV, though its clinical relevance is uncertain. The overall pharmacological profile supports traditional use for minor skin irritations and as a mild astringent.
