Trans-Resveratrol (Polygonum cuspidatum)

Trans-resveratrol is a secondary plant substance from the group of polyphenols. It is particularly abundant in the root of Japanese knotweed (Polygonum cuspidatum), a herbaceous plant in the knotweed family. The trans form is considered to be more bioactive and stable than the cis form.
Resveratrol has been scientifically studied for years, particularly with regard to its role as a polyphenol with antioxidant properties.

Botanical characteristics

  • Perennial herbaceous plant, up to 3 m tall
  • Hollow, bamboo-like stems
  • Broad-lanceolate leaves
  • Originally from East Asia, now also widespread in Europe (partly invasive)
  • The root (radix) is used primarily for medicinal purposes


Ingredients

Important ingredients of the root:

  • Trans-resveratrol (stilbene compound)
  • Piceid (glucoside of resveratrol)
  • Emodin (anthraquinone)
  • Other polyphenols and stilbenes

Although resveratrol is being intensively studied in research, there are currently no approved health claims under EU Regulation (EC) No. 1924/2006.


Traditional use

In East Asian medicine, the root is traditionally used for digestive complaints, circulatory problems and for general strengthening.

The trans form is considered to be more bioactive and stable and is therefore preferred in dietary supplements.

In which foods does resveratrol occur?
It is found in red wine, red grapes, peanuts and berries – but usually in small amounts.

When should you take resveratrol?
Best taken with a meal that contains some fat, as resveratrol is fat-soluble.

Are there any interactions with medications?
High doses can theoretically affect the effectiveness of anticoagulant medications – if in doubt, seek medical advice.
