Japanese Knotweed is the best-known bioavailable source of the potent antioxidant resveratrol. Most of the research has focused on the numerous benefits of resveratrol, but it also contains many other beneficial constituents which all play roles in affecting many different physiological processes including: supporting healthy blood vessel and cardiovascular function, helping to regulate bowel motility, antioxidant benefits, supporting proper liver function, and playing a role in steroid hormone conversion and metabolism. Our liquid herbs are the purest, and processed individually to ensure maximum efficacy. Due to their potency, we strongly recommend you seek the guidance from a Wellness Way Doctor with any questions you may have regarding the use of this herb.
