Japanese knotweed


Japanese knotweed—often just referred to as "knotweed"—is an invasive plant that makes enemies of gardeners, but it has plenty of fans in the natural health world. That's in part because knotweed is the #1 plant source of resveratrol, the antioxidant found in grapes and, famously, red wine. Resveratrol helps regulate the immune system, but you don’t have to sip a Merlot to get your dose of it; a knotweed supplement is the perfect alternative. In addition to packing a resveratrol punch, knotweed has other health benefits, too: In traditional Chinese medicine it’s been used to boost general wellness and treat bronchitis, cough, gingivitis, and inflammation of the mouth and pharynx. It also supports the treatment of pulmonary diseases, skin disorders, and tuberculosis, and acts as a diuretic. One type of knotweed root is even listed in the Chinese Pharmacopoeia!
