Reynoutria japonica, commonly known as Asian knotweed or Japanese knotweed, is a large, herbaceous perennial plant of the knotweed and buckwheat family Polygonaceae.

It is native to East Asia in Japan, China and Korea. In North America and Europe, the species has successfully established itself in numerous habitats and is classified as an invasive species in several countries.

Japanese knotweed has hollow stems with distinct raised nodes that give it the appearance of bamboo, though it is not related.

It is listed by the World Conservation Union as one of the world’s worst invasive species. The invasive root system and strong growth can damage concrete foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites. It can also reduce the capacity of channels in flood defences to carry water


Medicinal Action and Uses

Anti-aging – The herb contains lots of resveratrol which has been thought to be one of the best anti-aging compounds around.

Cognitive – one of the most well known and widely relied on benefits of Japanese knotweed is its apparent effect on cognitive disorders, like Alzheimer’s disease and dementia. This is primarily due to the resveratrol content of the herb.

Cardiovascular – the resveratrol in Japanese knotweed has been known to counter the development of heart disease and cardiovascular complications, such as high cholesterol with a high- fat diet.

Gastrointestinal – Japanese Knotweed can assist with gastrointestinal issues such as constipation, bloating, cramps, inflammation, or chronic pain. It also has mild laxative effects.
