Japanese Knotweed Root
Knotweed is used for swelling (inflammation) of the main airways in the lung (bronchitis), cough, sore throat, a mild form of gum disease (gingivitis), and other conditions
In addition to the popular antioxidant Resveratrol, Japanese Knotweed also contains a chemical known as emodin. Emodin has the ability to regulate bowel motility among other things. The Japanese used an alcohol extract of this plant as a natural laxative. Modern preparations from Japanese Knotweed are concentrated to maximize the Resveratrol and contain very little emodin. The phytochemical Resveratrol has garnered considerable scientific attention for its potential to support healthy blood vessel function and promote heart health.
There’s some promising research looking into Japanese knotweed as a treatment for Lyme disease
Knotweed is also traditionally used to treat a number of conditions, including respiratory issues and skin conditions. It’s used to stop bleeding, and as a mouthwash as well. There is some evidence that it may be helpful specifically for gingivitis
