Japanese Knotweed (Polygonum cuspidatum) is the premier botanical source of resveratrol, a highly bioactive polyphenol, along with polydatin and emodin. Resveratrol is a powerful sirtuin activator and antioxidant that crosses the blood-brain barrier, protecting neurons from oxidative stress, improving cerebral circulation, and suppressing systemic inflammatory cytokines. It is widely utilized in professional herbal protocols for tick-borne co-infections.
