Application

Rhizomes are dug up in autumn, in September - October (after the aerial part dies off) or in early spring, in April (before its regrowth).

The main thing is not to lay them out on a metal surface, since the tannins contained in them are destroyed by contact with iron.

Rhizomes contain tannins (15-20, and according to some authors - up to 35%) and coloring agents, starch (up to 26%), ascorbic acid and oxymethylanthraquinones, sterol, phenol carboxylic acids and their derivatives (caffeic, gallic, ellagic) coumarins, and the leaves contain vitamin C, carotene.
