Description Supplement Facts

Dong Quai (also known as Tang Kuei or Dang Gui) is a famous Chinese herb used for many menstrual irregularities. It is used in menopause to lessen the negative symptoms of hot flashes, mood swings, and irritability. It is also used in premenstrual (PMS) disorders to decrease the discomfort of cramps, slow onset, dull ache, mood swings, bloating, and irritability.

Dong Quai is an estrogen synergist. It sensitizes the binding or absorption sites where estrogen is absorbed into the body and will increase levels of estrogen in menopause symptoms. In PMS, Dong Quai accentuates the estrogen phase or phase from menses to ovulation. It is especially indicated for cycles longer than 28 days. It is contraindicated for cycles less than 28 days, which is estrogen excess (use Chaste Tree Berries here). Dong Quai will help bring longer cycles back to a 28-day cycle, help bring on a crampy slow onset period and possibly help alleviate a dry vagina.

Dong Quai helps swollen prostrates for men due to its ability to lessen pelvic congestion. It also purifies and nourishes the blood and has been found useful in the treatment of Anemia.
