The "Si Wu Tang" Herbal Formula

Si Wu Tang is a classic Chinese herbal formula for women, used for over 1,000 years to relieve PMS symptoms, improve circulation, enhance beauty and youth, and increase fertility.

While SWT is considered a tonic suitable for the average female, it is particularly meant for those suffering from what is known as blood deficiency and qi stagnation. Blood deficiency can be associated with backaches, anemia, vertigo, menstrual pain, and can be a cause of infertility (Taipei Medical University). Qi deficiency normally manifests as a lack of strength, body function decline, and lower immunity (Zhejiang Medical University).

Si Wu Tang means “four-substance decoction,” and this refers to the four herbs in the formula: angelica root, rehmannia, white peony root, and Sichuan lovage root. The formula is available in many forms—pills, powders, liquids, or dried herbs. I recently used the herbs to make chicken soup for a friend suffering from PMS symptoms. You can find this pre-packaged mix at Asian stores—see my 1/17 post for a recipe!

Studies on SWT published in scientific journals present fascinating findings:

SKIN & LIVER IMPROVEMENT: in a randomized, double-blind, placebo-controlled clinical trial, ingesting SWT for 6 months improved participants’ antioxidant levels and positively regulated the lipid profile, liver function, and skin integrity and texture

POSTPARTUM PAIN: according to a population-based correlational study, the bodily pain of postpartum women who used SWT was reduced by more than 10x those who did not

INFERTILITY: infertile women with ovarian follicular maldevelopment with an initial luteinizing hormone/follicle-stimulating hormone ratio of <1 saw this value return to normal and improved symptoms after taking SWT

CANCER CHEMOPREVENTION: prevention of oxidative damage by activating Nrf2-mediated detoxifying/antioxidant genes, suggesting that SWT might be an effective nontoxic agent for chemoprevention

SWT is traditionally taken at the end of the period for several days. It is generally considered safe, but consult a practitioner if you are suffering from specific issues.
