Angelica sinensis syn. A. polymorpha

Herbs gallery - Chinese Angelica



Common names

  • Chinese Angelica
  • Dang Gui
  • Dong Quai
  • Tang Kuei

The herbal product made from the Chinese angelica, also commonly called the dong quai, the dang gui, or the tang kuei is derived from the root of the Chinese herb - the Angelica polymorpha Maxim - botanical name. The variety of the species is sinensis Oliv. The herb is also known as A. sinensis (Oliv.), and it is a member of the plant family Apiaceae common in and native to China. The herbal remedies and herbal medication prepared from this herb has a mildly laxative effect on people, while, it is used primarily as a uterine tonic in women, it is also used as an antispasmodic herbal agent, and it is also used for its alterative-or blood purifying-effects, which are said to be very beneficial to affected patients.

This herbal remedy is very often suggested to patients by many modern herbalists to be used in the treatment of the majority of gynecological ailments and disorders, these conditions can include persistent menstrual cramps, the presence of some irregularity or a retarded menstrual flow, and to treat physical weakness during the menstrual period of affected women. While the use of the dong quai is not suggested in pregnant women, the remedy is also said provide physical relief from the many symptoms which occur during the process of menopause in women. The remedy is also known to be useful in the treatment of disorders such as hypertension and additionally, it is said to possess very effective antispasmodic properties in individuals afflicted by muscular spasms. The herb is also used to induce blood purification and to provide nourishment, for which it has a great reputation-and lastly, it has also been used in the treatment of constipation in individuals affected by this disorder.

Dong quai has been put under chemical investigation, and the herb is now known to possess at least seven different coumarin derivatives, these include the chemical compound oxypeucedanin, the compound osthole, the compound imperatorin, the compound psoralen, and bergapten-all of these compounds were present in the dong quai samples. The majority of chemical coumarins or its derivatives have known actions as vasodilators and antispasmodics in the human body, at the same time, a few of the others, such as the compound osthole, induce a stimulating effect on the central nervous system in the human body. The very presence of these chemical compounds therefore, accounts for at least some of the purported activities ascribed to dong quai.

Utilizing large and heavy doses of these coumarins often have harmful effects on the body, and it is known that some of the furo-coumarins, like the compound psoralen and the compound bergapten, may induce dermatitis in individuals exposed to them, due to the process of photosensitization which occurs because of their presence in the body. Unnecessary exposure of the human body to these compounds is undesirable according to studies done in the year 1981, during the course of which the researchers came to the conclusion that these so-called psoralens present very significant and sufficient risks to humans. Recommendation of very large amounts of the furo-coumarin-containing medications such as the dong quai is not made to treat patients for this very reason. At the same time, the absence of substantial clinical evidence in the Western scientific literature which may support the effectiveness of dong quai in the treatment of various conditions for which it is indeed suggested, also limits the use of this herbal remedy. For example, in the only reported U.S. based study on the potential effects of the dong quai on alleviating postmenopausal symptoms-including physical symptoms such as night sweats and hot flashes-found the herbal remedy equal in effectiveness to a placebo given to the test subjects. However, in traditional Chinese medicine, the dong quai remains as one of the most widely suggested medications and consequently, the remedy is far more popular in usage to other well known herbs such as the ginseng-which is quite well known in the western world. Various combinations of the dong quai with other herbs is the general prescribed avenue for patients and the herb is almost never used alone in most herbal medical systems. Further clinical studies are required on the potential benefits of this herb, before full acceptance in Western societies can be realized, and many controlled clinical studies still have to follow with regard to this herb. The use of this herb as a therapeutic agent has little basis and till such times.
