Dong quai (Angelica sinensis), also known as Chinese Angelica, has been used for thousands of years in traditional Chinese, Korean, and Japanese medicine. It remains one of the most popular plants in Chinese medicine, and is used primarily for health conditions in women. Dong quai has been called "female ginseng," based on its use for gynecological disorders (such as painful menstruation or pelvic pain), recovery from childbirth or illness, and fatigue/low vitality. It is also given for strengthening xue (loosely translated as "the blood"), for cardiovascular conditions/high blood pressure, inflammation, headache, infections, and nerve pain.

In the late 1800s, an extract of Dong quai called Eumenol became popular in Europe as a treatment for gynecological complaints. Recently, interest in Dong quai has resurged due to its proposed weak estrogen-like properties. However, it remains unclear if Dong quai has the same effects on the body as estrogens, blocks the activity of estrogens, or has no significant hormonal effects. Additional research is necessary in this area before a firm conclusion can be drawn.

In Chinese medicine, Dong quai is most often used in combination with other herbs, and is used as a component of formulas for liver qi stasis and spleen deficiency. It is believed to work best in patients with a yin profile, and is considered to be a mildly warming herb. Dong quai is thought to return the body to proper order by nourishing the blood and harmonizing vital energy. The name Dong quai translates as "return to order" based on its alleged restorative properties.

Although Dong quai has many historical and theoretical uses based on animal studies, there is little human evidence supporting the effects of Dong quai for any condition. Most of the available clinical studies have either been poorly designed or reported insignificant results. Also, most have examined combination formulas containing multiple ingredients in addition to Dong quai, making it difficult to determine which ingredient may cause certain effects.


DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Amenorrhea (lack of menstrual period): There is limited poor-quality study of Dong quai as a part of herbal combinations given for amenorrhea. Additional research is necessary before a firm conclusion can be drawn.
Grade: C

Angina pectoris / coronary artery disease: There is insufficient evidence to support the use of Dong quai for the treatment of heart disease.
Grade: C

Arthritis: Dong quai is traditionally used in the treatment of arthritis. However, there is insufficient reliable human evidence to recommend the use of Dong quai alone or in combination with other herbs for osteoarthritis or rheumatoid arthritis.
Grade: C

Dysmenorrhea (painful menstruation): There are unclear results of preliminary, poor-quality human research of Dong quai in combination with other herbs for dysmenorrhea. Reliable scientific evidence for Dong quai alone in humans with dysmenorrhea is currently not available.
Grade: C

Glomerulonephritis: There is insufficient evidence to support the use of Dong quai as a treatment for kidney diseases such as glomerulonephritis. Preliminary poor-quality research of Dong quai in combination with other herbs reports unclear results.
Grade: C

Idiopathic thrombocytopenic purpura (ITP): A poor-quality study reports benefits of Dong quai in patients diagnosed with idiopathic thrombocytopenic purpura (ITP). However, these patients were not compared to individuals who were not receiving Dong quai, and therefore the results can only be considered preliminary.
Grade: C

Menstrual migraine headache: The effects of Dong quai alone for this condition are not clear, and further research is necessary before a clear conclusion can be reached.
Grade: C

Nerve pain: There is insufficient evidence to support the use of Dong quai as a treatment for nerve pain. High-quality human research is lacking.
Grade: C

Pulmonary hypertension: It remains unclear if Dong quai is beneficial for other causes of pulmonary hypertension. Further research is needed before a strong recommendation can be made.
Grade: C

Menopausal symptoms: Dong quai is used in traditional Chinese formulas for menopausal symptoms. It has been proposed that Dong quai may contain "phytoestrogens" (chemicals with estrogen-like effects in the body). However, it remains unclear from laboratory studies if Dong quai has the same effects on the body as estrogens, blocks the activity of estrogens, or has no significant effect on estrogens.
Grade: D

Adults (18 years and older)

Dong quai is used in numerous herbal combinations, and various doses have been used both traditionally and in research in China. Because of this variation and lack of high-quality studies, no specific recommendations can be made. Safety and effectiveness are not established for most herbal combinations, and the amounts of Dong quai present from batch to batch may vary.

Powdered or dried root/root slices, fluid extracts, tinctures, decoctions, and dried leaf preparations of Dong quai are available to be taken orally. Topical preparations are available to be applied to the skin. Safety of intravenous use is not established, although it has been reported in research.

Children (younger than 18 years)

There is not enough scientific data to recommend Dong quai for use in children, and it is not recommended due to potential side effects.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


People with known allergy/hypersensitivity to Angelica radix or members of the Apiaceae/Umbelliferae family (anise, caraway, carrot, celery, dill, parsley) should avoid Dong quai. Skin rash has been reported with the use of Dong quai, although it is not clear if this was an allergic response. An asthma response has occurred after breathing in Dong quai powder.

Side Effects and Warnings

Although Dong quai is accepted as being safe as a food additive in the United States and Europe, its safety in medicinal doses is not known. There are no reliable long-term studies of side effects. Most precautions are based on theory, laboratory research, tradition, or isolated case reports.

Components of Dong quai may increase the risk of bleeding due to anticoagulant and anti-platelet effects. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Discontinue use prior to surgical or major dental procedures.

It remains unclear if Dong quai has the same effects on the body as estrogens, if it blocks the activity of estrogens, or if it has no significant hormonal effects. It remains unclear if Dong quai is safe in individuals with hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, or endometriosis. It is not known if Dong quai possesses the beneficial effects that estrogen is believed to have on bone mass or potential harmful effects such as increased risk of stroke or hormone-sensitive cancers.

Increased sun sensitivity with a risk of severe skin reactions (photosensitivity) may occur due to chemicals in Dong quai. Prolonged exposure to sunlight or ultraviolet light should be avoided while taking Dong quai.

Safrole, a volatile oil in Dong quai, may be carcinogenic (cancer-causing). Long-term use should therefore be avoided, and suntan lotions that contain Dong quai often limit the amount of Dong quai to less than one percent.

Dong quai has traditionally been associated with gastrointestinal symptoms (particularly with prolonged use), including laxative effects/diarrhea, upset stomach, nausea, vomiting, loss of appetite, burping, or bloating. Published literature is limited in this area.

Dong quai preparations may contain high levels of sucrose, and should be used cautiously by patients with diabetes or glucose intolerance.

Various other side effects have rarely been reported with Dong quai taken alone or in combination with other herbs. However, side effects have not been evaluated in well-designed studies. These include: headache, lightheadedness/dizziness, sedation/drowsiness, insomnia, irritability, fever, sweating, weakness, abnormal heart rhythms, blood pressure abnormalities, wheezing/asthma, hot flashes, worsening premenstrual symptoms, reduced menstrual flow, increased male breast size (gynecomastia), kidney problems (nephrosis), or skin rash.

The safety of Dong quai injected into the skin, muscles, or veins is not known and should be avoided.

Pregnancy and Breastfeeding

Dong quai is not recommended during pregnancy due to possible hormonal and anticoagulant/anti-platelet properties. Animal research has noted conflicting effects on the uterus, with reports of both stimulation and relaxation. There is a published report of miscarriage in a woman taking Dong quai, although it is not clear that Dong quai was the cause. Dong quai is traditionally viewed as increasing the risk of abortion. There is insufficient evidence regarding the safety of Dong quai during breastfeeding.


Interactions with Drugs

Dong quai may increase the risk of bleeding due to anticoagulant and anti-platelet effects, and may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).

It remains unclear if Dong quai has the same effects on the body as estrogens, if it blocks the activity of estrogens, or has no significant hormonal effects. It is not known if taking Dong quai increases or decreases the effects of birth control pills or hormone replacement therapy such as Premarin®, which contains estrogen, or the anti-tumor effects of selective estrogen receptor modulators (SERMs) such as tamoxifen.

Chemicals in Dong quai may cause increased sun sensitivity with a risk of severe skin reactions (photosensitivity), and Dong quai should be avoided with other drugs that cause photosensitivity, such as tretinoin (Retin-A®, Renova®), and some types of anti-depressants, cancer drugs, antibiotics, or anti-psychotic medications. Patients taking medications should check with their doctor or pharmacist before starting Dong quai.

Based on laboratory research, Dong quai may increase the effects of drugs that affect heart rhythms, such as digoxin, beta-blockers such as metoprolol (Lopressor®, Toprol®), calcium channel blockers such as nifedipine (Procardia®), or other anti-arrhythmic drugs.

Based on laboratory research, some compounds in Dong quai may increase the effects of anti-cancer drugs and antidepressant drugs called selective serotonin reuptake inhibitors (SSRIs).

Interactions with Herbs and Dietary Supplements

In theory, due to anticoagulant and anti-platelet effects, components of Dong quai may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.

It remains unclear if Dong quai has the same effects on the body as estrogens, blocks the activity of estrogens, or has no significant hormonal effects. The effects of agents believed to have estrogen-like properties may be altered.

Chemicals in Dong quai may cause increased sun sensitivity with a risk of severe skin reactions (photosensitivity), and Dong quai should not be taken with products containing Hypericum perforatum (St. John's wort) or capsaicin, which are also reported to cause photosensitivity.

Based on laboratory research, some compounds in Dong quai may increase the effects of anti-cancer herbs or supplements and antidepressants.

Dong quai may increase the effects of antioxidants.
