Akebia quinata (mu tong)
Akebia quinata also known as: mu tung (mu tong)
OTHER NAMES: tung tsao (perforated grass)
A climbing vine with a jointed, woody stem that varies in thickness from 1-7 centimeters, the plant is distinguished by small tubular holes in the marrow, large enough for air to be blown through, hence the Chinese name mu tung, "perforated wood." The wood is yellow and arranged in vascular plates. The medicinal part is sold in sliced transverse sections of the ligneous (woody) stem, about 1 centimeter in diameter, and contains 30% potassium salts, which accounts for its diuretic action. The fruit is edible and has a white pulp with black kernels and a pleasant sweet taste.
The plant is native to eastern China and Japan.
