What Are the Benefits of Japanese Knotweed?


Japanese knotweed is a hardy plant that grows quickly, spreads rapidly and thrives in all types of environments. Outside of its native Japan, it is considered to be an invasive plant due to its ability to enter new territory and swiftly replace existing plant life. But Japanese knotweed also offers a number of benefits.


During the 1800s, Japanese knotweed was introduced to Europe and North America as an ornamental plant.


Distinguished by its tall, bamboo-like stalks and small white flowers, Japanese knotweed is still used in gardens today.


Japanese knotweed can be used as a natural way to maintain bowel regularity and treat constipation.


Japanese knotweed is high in resveratrol, a powerful antioxidant that is widely believed to help reduce bad cholesterol and prevent heart disease.


Japanese knotweed tastes similar to rhubarb. It can be eaten as a steamed vegetable or used as a flavorful ingredient in everything from soups to desserts.

Fun Fact

Beekeepers appreciate Japanese knotweed because its flowers provide honeybees with an important source of nectar. The resulting honey, called "bamboo honey," is very sweet.
