Chinese wild yam, Japanese mountain yam, it is just good stuff!

Dioscoreae Oppositae - its English pharmaceutical name, or commonly Chinese wild yam, you can call it. Its other name - nagaimo, or Japanese mountain yam.

Seen them in Asian supermarkets, especially Japanese supermarkets such as Mitsuwa in the United States, but never tried them in my cooking. Seen them in Taiwan again and decided to have a simple stir fry to this. It's rather common in Taiwan and the people here believe this tuber has beneficial properties. In Mandarin, call it 淮山 ~ pronounced huai shan; or 山药 ~ pronounced shan yao. 山药 literally meaning "medicine of the mountain" - this tuber vegetable indeed has its healing properties. This wild yam even has sexual lubricating characteristics, as documented in Wiki.

Numerous tiny channels in the yam cross-section, are channels that produce the "slime"

This tuber vegetable is starchy and mucilaginous (slimly, gelatinous, sticky) when grated/sliced, and may be eaten plain (esp. those grown in Japan), as a side dish, or added to noodles. Can you see the numerous tiny round channels in the cross-section ? These are channels that produce the "slime". The long tuberous roots are cultivated for pharmaceutical as a superior herb. The dried white flesh of the tuber is sliced into long thin slabs and contains nutrients which can restore and enhance immune functions throughout the system. You can usually find these dried white flesh of thin tuber slabs, packaged with other dried Chinese herbs and sold as a complete Chinese tonic pack. I had a steamed herbal chicken recipe using Chinese dried herbs of dioscoreae oppositae and other herbs before.
