Scientific Data and Mechanism:Eucommia Bark Hypotensive Effects.

Eucommia Bark Extract INCI Name Eucommia Ulmoides Extract CAS 223749-00-6 Cortex Eucommiae Eucommia Ulmoides Cortex Eucommia ulmoides oliv photo picture image Eucommia ulmoides has been found to contain hypotensive compounds in 1974 at the University of Wisconsin. Since that time numerous studies have been conducted which have clarified the hypotensive effects of Eucommia. The hypotensive action has been demonstrated in numerous animal models and in humans. Hypotensive compounds exist in both the bark and leaves. The hypotensive compound has been determined to be pinoresinol diglucoside. The chemical structure has been determined and it has been synthesized.

The precise hypotensive mechanism has not been fully determined. Most studies indicate that the hypotensive action is a consequence of central inhibition. But conflicting studies indicate direct dilatory action on the vascular musculature.

Eucommia has been shown to markedly reduce cholesterol absorption in laboratory animals. 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 function.

Decoctions of this herb have 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. Many studies have proven that Eucommia potentiates the immunologic functions of the body.

Clinically, the hypotensive action of the herb has been studied in several large clinical studies. In each case, the effective rate reached around 80% after 30 days of administration. The results have clearly shown that water extraction is effective, but that alcohol extraction is ineffective. Eucommia has been shown to have a mild diuretic action.

The hypotensive effect has been shown to be increased even further by combining with Lonicera japonica, Scutellaria baicalensis, Prunella vulgaris fruit clusters, and Loranthus parastiticus, all herbs traditionally prescribed to reduce high blood pressure. Using this combination, results were quick and effective in over 90% of the patients in the study. After just one week, most patients experienced a marked reduction in blood pressure, a stable emotional state and felt mentally refreshed and relaxed. The symptoms of tinnitus and numbness were relieved. The patients also reported marked amelioration of headaches, dizziness, palpitation, insomnia, chest discomfort and difficult mobility.

In a clinical study of 121 people with various types of arthritis and lumbago, a preparation made from the leaves of Eucommia had a marked effective rate of over 87%.

In another clinical study of 40 patients diagnosed as suffering from chronic strain of the lumbar muscles and lumbar osteoarthrosis, a Eucommia-based formula proved to be highly effective in relieving the symptoms. The Eucommia bark extract was combined with Psoralea corylifolia and Walnut kernel.
Eucommia has been found to induce interferon production in human beings.
