We have been culturing and producce iron bar yam for many years
Chinese yam (Dioscorea opposita) is a root that is used in traditional Chinese medicine. The Chinese pharmaceutical name for this herbal is Rhizoma
dioscoreae. Other names for Chinese yam include dioscorea and shan
yao. Chinese yam is native to China, Japan, Korea, and Taiwan,
where it can be found growing wild on hill slopes and in valleys.
It is also propagated for medicinal and dietary uses.
The genus name Dioscorea is dedicated to the Greek physician and
naturalist, Diosorides. There are between 600 and 800 different
species of Dioscorea, making it one of the largest genera of the
plant kingdom. Many species in this genus are grown and collected
for their medicinal properties. Sweet potatoes are often called
yams, although they are different plants.
The Chinese yam plant is a climbing vine that supports itself by
coiling around the branches of other vegetation. The plant can be
9.75 ft (3 m) high and 5 ft (1.5 m) wide. Chinese yam has
heart-shaped leaves and it produces small white flowers which have
a cinnamon-like aroma. Small tubers (called tubercles) form in the
axials (the angles between the leaves and the stem). These
pea-sized tubercles are harvested in the late summer or early fall
and are used to propagate the plant.
Chinese yam plants take three or four years to reach maturity,
although fairly large roots may be harvested from well developed
plants after the first year. Chinese yam is a spindle-shaped,
thick, hard root or tuber that is white on the inside. However,
cultivated forms from China or Japan may have different root
shapes. The yam may be up to 1 yd (about 1 m) in length. Chinese
yam is dug up in the winter. After the rough bark is removed, the
root is washed and allowed to dry in either the shade or the sun.
The dried root is rehydrated in water and then cut into slices.
Chinese yam contains large amounts of mucilage. Mucilage is a
thick, slimy substance produced by plants. It has a soothing effect
on mucous membranes, such as the tissues that line the respiratory
passages. This may explain why Chinese yam is effective at

Traditional Chinese medicine classifies Chinese yam as neutral and sweet. It serves to tonify
and augment the spleen and stomach; augment the lung yin and tonify
the lung qi; and stabilize, tonify, and bind the kidneys. Chinese yam enters through the spleen, lung, and kidney channels (meridians).
