What is Japanese Knotweed Root?

Japanese Knotweed Root, also known as Hu Zhang (You Ji Hu Zhang) or Polygonum Cuspidatum, is a perennial plant native to East Asia. For centuries, it has been a central element in traditional Chinese medicine. This NU HERBS product comes as a fine powder, obtained from organic roots grown in China, and is packaged in a tamper-evident, resealable bag.

Japanese Knotweed is especially known for being a natural source of bioactive compounds such as resveratrol and emodin. However, it is important to remember that food supplements should not be used as a substitute for a balanced diet. Always consult a healthcare professional before incorporating any supplement into your routine.

Quality and manufacturing standards

NU HERBS is committed to offering products of the highest quality. This root powder is of pharmacopoeia grade, meaning it meets or exceeds the standards of the Chinese Pharmacopoeia. Unlike common food grades, pharmacopoeia grade guarantees superior purity and potency for the product to fulfill its intended purpose.

Manufacturing is carried out in GMP (Good Manufacturing Practices) certified facilities, both in China and the United States. In addition, the company performs double testing: independent analysis in US laboratories and internal controls in its own facilities. This includes testing for heavy metals, microbial contaminants, and pesticide residues, offering exceptional traceability and safety.

Single ingredient: Polygonum Cuspidatum

The product contains a single ingredient: organic Japanese Knotweed root powder. No excipients, binders, or other additives are added. Each batch undergoes rigorous controls to ensure its botanical identity and purity.

This plant has been of interest in modern research, especially for its resveratrol content, a polyphenol with antioxidant properties. However, it is important to note that health claims must be authorized by the EFSA. Currently, no specific health claims have been established for Japanese Knotweed in the European Union. Therefore, this product is presented as an herbal food supplement for traditional consumption.
