Japanese Knotweed Tincture, a potent and local source of resveratrol, can be effective at reducing inflammation in your body. According to this article, ” Japanese Knotweed (polygonum cuspidatum) improves inflammation and alleviates oxidative stress. Chronic inflammation is a contributing factor of age-related diseases and conditions such as diabetes, cardiovascular and autoimmune diseases (3). Inflammation and oxidative stress go hand-in-hand in that the inflammatory process induces oxidative stress, which in turn reduces the antioxidant defense system.” A 2010 study with 20 adults taking Japanese Knotweed/polygonum cuspidatum resulted in a significant reduction in all the testing parameters for oxidative and inflammatory stress (4).
