What is Cornus officinalis?
Cornus (Cornus officinalis) is a tree used in Chinese medicine. Its Chinese name is shan zhu yu. Cornus is shrub that grows to a height of 30 ft (10 m) in the woodland regions of East Asia from China to Korea. The fruit is used in healing. It is harvested when ripe, then dried for future use. The small fruits can also be eaten as food, either raw or cooked. They contain about 8.6% sugar and have a slightly astringent taste. The bark from the stem is also used as an anti-malarial tonic.
Cornus has been used in China for more than 2,000 years. In the Chinese system of health, yin aspects must be kept in balance with yang aspects. Ill health occurs when the energies and elements of the body are out of balance or in disharmony. Health is restored by taking herbs and treatments that restore this balance.
Cornus berries have a long history of use in a variety of medicinal tonics, including those used to treat excessive urination, incontinence, excessive sweating, excessive menstrual bleeding, decreased erectile function and premature ejaculation. Cornus is also an ingredient in formulas that treat ringing of the ears (tinnitus), poor hearing, blurred vision, dizziness, shock and trauma, and a wide range of other conditions.

Benefits of taking Cornus officinalis Extract supplements:
Cornus is rarely used alone. It is an ingredient in many herbal formulas where it is used to stabilize and bind. It has astringent properties that are thought to boost the power of other herbs. Cornus can be combined with both yin and yang herbs to remedy deficiencies in either area because it conserves jing, the essence of life. In Chinese medicine jing, when referring to a man, means sperm. The ability to conserve jing is a result of the stabilizing and binding properties and the ability to control body fluids.
Although the results are not completely clear, some studies have shown that the fruit of cornus has antibacterial and antifungal properties. In some studies extracts of the fruit inhibited the growth of some strains of Staphy-lococcus bacteria. It may also be effective against Salmonella and Shigella, both bacteria that cause gastrointestinal disturbances.
Cornus fruit is also used in formulas that strengthen the back and knees, both areas associated with kidney jing. It is also used in formulas that control body fluids and treat excessive sweating, urine leakage, sperm leakage (spermatorrhea), and heavy, prolonged menstruation. Cornus is also an ingredient in formulas that treat ringing of the ears (tinnitus), poor hearing, dizziness, extreme shock, and a wide range of other conditions. The bark is boiled, and the resulting astringent decoction is used in formulas that treat fevers and as an anti-malarial. Interestingly, in Western herbalism the bark of dogwood, cornus’s cousin, is also used against malaria. Cornus is also used to treat diabetes, arthritis, and impotence.
Two Chinese studies published in 1997 and 1998 in The American Journal of Chinese Medicine found that extracts of cornus increased the blood flow to the kidney and spleen and increased the motility of human sperm. Few scientific studies have been done on this herb outside of China.
