Wild yam (Dioscorea villosa): Wild yam belongs to the yam family and has underground storage organs. It is native to North America.
The material composition is interesting. Characteristic ingredients are certain steroidal saponins, including precursors of diosgenin. Plant diosgenin is not converted directly into progesterone in the human body.
In herbal lore, the distinction between leaves, fruits, seeds, roots and bark is important. The individual parts of a plant can contain very different groups of substances. A figure such as 4:1 or 10:1 describes the ratio of starting material used to the amount of extract obtained, not automatically the concentration of a single active ingredient.
A look at the form of raw material used reveals further special features. Wild yam is a plant with a long tradition. The most important declared plant substance in this product is diosgenin, a sapogenin from the group of triterpenes.
