Japanese Knotweed / Resveratrol
Reynoutria japonica
Japanese knotweed is the richest plant source of resveratrol — a potent polyphenol studied in thousands of cancer research papers. Resveratrol activates SIRT1, inhibits NF-κB, induces apoptosis across multiple cancer types, reduces angiogenesis, and shows synergy with conventional chemotherapy. Trans-resveratrol from knotweed root is the most bioactive form.
