Dong quai (Angelica sinensis)

Immune stimulant

Dong quai stimulates the immune system.

Traditional Chinese medicine uses dong quai root as an immune stimulant. A study reported in the 2006 issue of “Planta Medica” tested a formula containing dong quai and astragalus roots that was described in 13th century Chinese medical texts. The researchers found that this concoction increased the activity of T-lymphocytes and macrophages, key cells involved in the body’s immune response. The formula was most powerful when the ratio of astragalus to dong quai was 5:1, just as the ancient Chinese texts recommend.


The estrogenic effect of dong quai indicates that women with hormone-sensitive cancers should avoid this herb (Eagon et al., 2000).

Do not use dong quai if you are taking blood thinners, since it may enhance the effects of your medication.
