One of the very few
balanced vegetarian Yang and Yin tonics
Eucommia is the primary
plant-sourced herb in Chinese herbalism used to tonify the Kidney Yang
functions, in particular as it affects the lower part of the body and the
skeletal structure. And although
Eucommia is primarily known as a powerful Yang Jing tonic, it is also a strong
Yin Essence (Yin Jing) nourishing herb.
Because it provides both Yin and Yang, it is a superb herb for men and
women alike and can be used by almost anybody to promote the functions of the
endocrine system, to promote sexual functions, to enhance normal growth, to
promote healing, to strengthen the physical structure and to strengthen
resistance. Recent animal studies indicate that the alcohol extract of Eucommia
Bark may be a potent human growth hormone secretagogue.
Eucommia’s first fame is in
its Kidney tonifying effects. It is in fact the primary herb in Chinese tonic
herbalism for building a strong, sturdy, flexible skeletal structure. It is used to strengthen the bones,
ligaments and tendons, and can be used to help mend damage to these tissues,
whether the damage is due to stress, age or trauma. Eucommia is also the
primary herb of choice for lower back and knee problems, including pain,
stiffness, dislocation, swelling and weakness. Eucommia is one of the few herbs
in Chinese tonic herbalism that is sufficiently powerful, balanced and broad
spectrum that it may be used alone. However, it may be combined with any number
of other tonic herbs in a formulation or tonic herbal program designed to build
the Yin and Yang of the Kidney.
Eucommia is the quintessential
example of a safe, mild and potent Kidney tonic that builds Jing.
As a Kidney tonic, Eucommia is
considered an important herb for improving potency in men and fertility in
women. It will be found in almost
every formula designed for such purposes.
Furthermore, Eucommia helps slow down ejaculation.
Scientific Knowledge: In 1974
researchers at the University
of Wisconsin found
Eucommia ulmoides to contain hypotensive compounds. The hypotensive action has
been demonstrated in numerous animal models and in humans. The hypotensive
compound has been determined to be pinoresinol diglucoside.
Eucommia has been shown to markedly
reduce cholesterol absorption in laboratory animals (not proven in humans). It
has also been shown to have mild sedative and anti-inflammatory action in
pharmacological experiments. The experimental results indicate that one of the
anti-inflammatory mechanisms of Eucommia involves enhancement of the
adrenocortical function. This supports the traditional theory that Eucommia
tonifies the Kidney function, which is now known to involve adrenocortical
1. Eucommia extract has been shown
to have powerful effects on the immune systems of various laboratory animals.
In particular, it appears that Eucommia significantly enhances phagocytic
action. Phagocytosis involves the clearing away of foreign material from the
blood stream by the white blood cells. In this particular action, Eucommia
proved to be as powerful as Astragalus
membranaceus and Codonopsis pilosula,
two herbs that have been proven to have powerful immunological activity in
animals and humans.
An active constituent of Eucommia
bark is aucubin. Studies indicate that aucubin may play a role in protecting
the skin from UV radiation and therefore from photoaging.
2. Ultraviolet-B (UVB) irradiation
has been demonstrated to produce reactive oxygen species (ROS) in the cells and
skin, which induces the synthesis of matrix metalloproteinases (MMPs), causing
skin photoaging. Using the human skin fibroblast HS68 cell line in the present
study, we investigated the photoprotective effects of aucubin from Eucommia
ulmoides. Pretreatment with aucubin significantly inhibited the production of
MMP-1 by 57% when compared to the UVB-irradiated cells. Additionally, the
senescence-associated beta-galactosidase (SA beta-gal) activity was markedly
decreased in the presence of aucubin, which indicates it as an anti photo-induced
aging compound. As the effect of aucubin was determined against ROS, the
inhibited ROS formation and malondialdehyde (MDA) levels, and the increased
cell viability and glutathione (GSH) level were observed with aucubin under UVB
irradiation. Based upon these results, it was suggested that aucubin might play
an important role in the cellular defense mechanism against UV
radiation-induced photoaging. An understanding of the antioxidant properties of
aucubin could, in part, act to elucidate its protective mechanism on the human
These results suggest that aucubin
is a photoprotective phytochemical, and could be used as a potential agent in
