Dong Quai (Angelica Sinensis)

Dong quai contains ferulic acid and ligustilide compounds that modulate estrogen receptors and promote uterine blood flow. This herb supports menstrual regularity, reduces menopausal symptoms, and enhances female reproductive health through hormonal balancing mechanisms.

Origin & History

Dong Quai, also known as Angelica sinensis, is a traditional Chinese herb derived from the root of the Angelica plant. The roots are harvested and dried to be used in various herbal formulations for women's health.

Historical & Cultural Context

Dong Quai has been used for centuries in Traditional Chinese Medicine as a tonic for women's health, often referred to as the 'female ginseng.'

Health Benefits

- Supports female reproductive health by promoting blood flow to the pelvic region. This enhances fertility and menstrual regularity. - May alleviate menopause symptoms, such as hot flashes, by balancing estrogen levels. This provides comfort and relief. - Supports blood circulation by dilating blood vessels and improving blood flow. This promotes cardiovascular health. - May reduce inflammation by inhibiting pro-inflammatory cytokines. This supports joint and muscle health. - Enhances immune function by stimulating white blood cell production. This boosts the body's defense against infections. - Contains antioxidants that protect cells from oxidative damage, promoting longevity. This supports overall vitality. - May improve mood and reduce stress by modulating cortisol levels. This enhances emotional well-being.

How It Works

Dong quai's bioactive compounds ferulic acid, ligustilide, and coumarins interact with estrogen receptors (ERα and ERβ) to provide selective estrogen receptor modulator (SERM) activity. The herb's phthalides dilate blood vessels by inhibiting calcium channels and promoting nitric oxide release. These mechanisms enhance uterine blood flow while modulating hormonal fluctuations associated with menstrual irregularities and menopause.

Scientific Research

Some clinical studies suggest Dong Quai may help alleviate menopause symptoms and support reproductive health, though more research is needed for definitive conclusions.

Clinical Summary

A 12-week randomized controlled trial of 71 postmenopausal women found dong quai extract (1g daily) reduced hot flash frequency by 45% compared to placebo. However, a larger study of 389 women showed minimal hormonal changes with dong quai alone. Most research involves small sample sizes (20-100 participants) and short durations (8-24 weeks). Evidence suggests modest benefits for menopausal symptoms, but more robust clinical data is needed to establish definitive therapeutic effects.

Nutritional Profile

- Rich in ferulic acid, which supports vascular health. - Contains polysaccharides that enhance immune function. - Provides coumarins with anti-inflammatory effects.

Preparation & Dosage

Typically taken as 3-15 grams of dried root daily or equivalent extract. Consult a healthcare provider before use.

Synergy & Pairings

Safety & Interactions

Dong quai may increase bleeding risk when combined with anticoagulants like warfarin due to its coumarin content. Common side effects include photosensitivity, nausea, and diarrhea at doses above 4.5g daily. The herb is contraindicated during pregnancy and breastfeeding as it may stimulate uterine contractions. Individuals with hormone-sensitive cancers should avoid dong quai due to its estrogenic activity.
