Curled-leaved St. John's-wort
Hypericum triquetrifolium
Hypericum triquetrifolium, a plant native to certain regions in Europe and Asia, has not been extensively used in traditional medicine. Scientific studies have shown that hydroalcoholic extracts of this plant exhibit strong antioxidant and anti-inflammatory properties, with selective cytotoxicity against pancreatic cancer cells. However, there is no significant evidence for antimicrobial or general cytotoxic activity. The essential oil and aroma components from 21 different locations of Hypericum triquetrifolium have shown moderate antioxidant capacity and varying levels of enzyme inhibition, including cholinesterase, tyrosinase, and urease. While the plant does not appear to pose major safety concerns or interact with drugs, these findings are based on limited research and further investigation is warranted.
