Si Wu Tang has improved menstrual symptoms by increasing estradiol content and antioxidative effects as a result of its herbs' synergistic relationships.

Experimental Study Oestradiol Shao Yao Shu Di Huang

In the methodology of the study, a testosterone-treated MCF-7 cell model was employed to determine the effects of each herb in the SWT formula. Key metrics that were considered included the regulation of estradiol, antioxidative effects, and the total polyphenol and polysaccharide contents as quality markers. The study also explored the potential ability of certain elements within the formula to act as an aromatase promoter, notably catalpol and other elements.

In terms of results, certain herbs in SWT such as catalpol showed an ability to significantly increase estradiol content and boost upregulation in cell culture, indicating their role as potential aromatase promoters within the formula. Antioxidant activity was also strong in other compounds like pentagalloylglucose, gallic acid, and ferulic acid. These antioxidative effects were attributed to the presence of polyphenols in the herbs. Furthermore, the herb with the strongest antioxidant effects could possibly help ameliorate menstrual disorder patterns due to its ability to prevent ROS damage to the ovaries.
