Hemp (Dama), also known as Fire Hemp (Huoma) or Yellow Hemp (Huangma). There are five varieties of hemp. The fiber of Huangma is white, and its leaves are palmately lobed into five segments; the leaves of Ramie (Zhuma) are unlobed. Both Ramie and Huangma are processed by peeling the bark to obtain the fiber. The stem of Ramie is white with ridges, light and hollow, and can be used as candle wicks.

The seed of Hemp (Maren) has a sweet taste and neutral qi. Its nature is slippery, lubricating, and descending. It moves without staying fixed.
