Hemp Seed (huo ma ren)

What is hemp seed? What is it used for?

Hemp seeds come from the hemp plant (cannabis sativa L), an annual herb that grows throughout the world's temperate regions. The plant can reach a height of approximately 30 inches, and flowers during the summer. The seeds are harvested in autumn; they are pounded or powdered, and taken raw for use. Hemp seeds contain a fatty oil, and are a good source of many essential fatty acids.

Hemp has a long history of medicinal use. In traditional Chinese medicine, hemp seed has sweet and mild properties, and is associated with the Spleen and Large Intestine channels. Traditionally, it is used as a laxative to loosen the bowels and relieve constipation. Many practitioners prescribe it to help relieve pain, induce sleep, and treat nausea associated with chemotherapy. It also has a soothing effect on some nervous disorders, such as multiple sclerosis, and has been used to relieve pressure in the eye caused by glaucoma. When treating constipation, hemp seed is often used with other herbs, such as rhubarb and magnolia bark.

How much hemp seed should I take?

The typical dosage of hemp seed is between 10 and 30 grams, used in a decoction. It is usually mashed or powdered before being added to water. Some practitioners also provide concentrated hemp seed extracts (in a 5:1 ratio); for extracts, the recommended dose is 2-3 grams per day.
