We will be most interested in the brown, six to thirteen millimeter thick rhizome from which they grow
hairy roots. The rhizomes are markedly aromatic and contain a high concentration of saponins. In addition to saponins, soap also contains carbohydrates, resins, mucilages, rubber and mineral acids. The rhizomes are collected from two- to three-year-old plants, best excavated between September and November, or early spring (March to April). Sometimes the stem is collected, which contains the same substances, but in smaller quantities. The stem is collected at the beginning of flowering. After washing with cold water, the rhizomes are dried in a well-ventilated place, either in the sun or in a dryer at temperatures up to 60 ° C.
