Chinese Yam
Known as nagaimo in Japan as well as "cinnamon vine" or "air potato" in the United States, the Chinese yam (Dioscorea batatas) is popular in Asia as both a cooking ingredient as well as a natural home remedy for indigestion and women's reproductive health. Historically, this yam has been used in traditional Chinese medicine to treat ailments of the stomach, spleen, and kidneys. For this reason it is also known by the name shanyao (Chinese: "mountain medicine").The root bulbs contain diosgenin, a type of phytoestrogen (plant-based estrogen), which is a precursor for many hormones.
This tuber was popularised by Rudolf Steiner in the West because of the anthroposophical importance he attributed to the Chinese yam. We source our yams directly from Mecklenburg-Western Pomerania, where they are grown according to strict cultivation guidelines. We exclusively offer the powder made from whole tubers of the male plants, which has been hand-milled at a distance from electromagnetic fields.
Yams
Although sweet potatoes are often referred to as yams, true yams and sweet potatoes belong to completely different families of tuber crops. There are hundreds of variants of yams native to Asia, Africa, as well as North, South and Middle America, and they are popular in cuisines all over the world. Yams may be cooked similarly to sweet potatoes, but their rougher skins and starchy flavour are distinctive.
Because our Chinese yam powder is a natural product, there may be slight variation between batches.
