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.
