Dong Quai (Angelica sinensis) is one of the most powerful females tonic and fertility herbs. Used since at least the first century, dong quai tonifies and strengthens the uterus by regulating hormonal control, improving uterine tone, and improving the timing of the menstrual cycle. In Asia dong quai is to women’s health as ginseng is to men’s health.
In traditional Chinese medicine Dong Quai is referred to as a blood tonic as it has a general effect on circulation. This could be helpful for women experiencing pale menstrual flow, absent periods, and weakness after periods (in TCM this is called blood deficient). It has also been shown to improve red blood cell counts. Dong quai is traditionally used for situations of stagnation (PCOS, endometriosis, ovarian cysts, and fibroids) as it increases the blood flow to the reproductive system reducing congestion and pain.
Dong Quai may be helpful for:
- Menstrual irregularities
- Delayed or absent menstruation
- Short periods with cramping
- Strengthening a “weakened uterus”
- If you experience cramping and PMS during your period.
- Women who have stopped taking birth control pills and need to encourage a regular cycle
- Light or slow starting menstruation
- Stagnant conditions
How Dong Quai WorksDong Quai works by promoting blood flow to the pelvis where it will stimulate an absent or scanty period. It also nourishes the blood (it is in nearly all Chinese herbal blood-building formulas) and helps iron deficiency and anemia. One of the best uses is it helps women who are not menstruating to invite there menstruation back. The increased circulation also helps to strengthen and balance the uterus. In rat studies it has been show to help build the uterus lining.
Dong Quai also has a relaxing effect on both the uterus and the nervous system. This can be helpful in situations such as PMS and cramping during your period. It’s relaxing effects are just as powerful as well known herbs lavender, chamomile, or valerian root.
