Eucommia Ulmoides

Du Zhong

by Robert Bidleman

One of the oldest known herbs in the Chinese system, Eucommia the only member of this family [Ulmoides], has been known for over three thousand years. Untill recently Eucommia was little known in the West due to it's scarcity. Traditionally the bark was used but recent research (Japan and China) has shown that the leaves are also effective. Primarily used for its value in regulating blood pressure Eucommia is also regarded highly for use as a longevity herb second only to Ginseng. This is attributed to the tonic effect it has on the liver and kidneys. In Japan Eucommia is currently being marketed for its actions as an anti-inflammatory and as a sexual tonic. Many people use it for lumbago in Asia. The new popularity it is enjoying in Japan however is connected to the weight loss claims many users experience. It reportedly stifles the craving for food (see below). The bark which contains the rubbery latex substance one would expect from such a tree is more medicinal than the leaves. The leaves may be used as an adaptogen and unlike the bark may be consumed for long periods of time. Although producing a rubbery latex like the rubber trees, Eucommia is actually the singular tree in a family which was once widespread in Europe and the America's but which are now extinct save for this one example. The Chinese name Du Zhong refers to a Taoist monk who was reported to be immortal perhaps referring to the tree's value as a longevity herb. It is known for it's ability to enhance the vital energies and increase the essence. Starting in 1948 Russia, China, Japan and American research teams have reported its effectiveness as a sedative, tonic, anti-inflammatory and diuretic. This was research of the tree bark and the leaves were considered valueless. The recent research which has shown the milder effects of the leaves has also reported even more benefits over a long period of time. Longevity and weight loss have made this particular herb a veritable boon in Japan. It's use has been reported to diminish craving for food and taken in the evening it prevents late night 'snacking'. Eucommia's anti-hypertensive properties come without the side- effects of many drugs used for this condition. The concurrent use of ginseng, eucommia, schizandra, astragalus and Ho Shou Wu have been reported to be the same secret formula that the reknowned Moo San Do Sha who lived to be 142 years of age used.
