Si Wu Tang is primarily composed of four medicinal ingredients: Angelica sinensis (Dang Gui), Rehmannia glutinosa (Shu Di Huang), Paeonia lactiflora (Bai Shao), and Ligusticum chuanxiong (Chuan Xiong). It generally has functions of nourishing kidney and strengthening yang, soothing the liver and fortifying the spleen, beautifying the complexion, regulating menstruation and relieving pain, as well as nourishing and enriching blood. It is typically consumed 3 to 7 days after menstruation ends. Detailed explanation is as follows:

I. Functions and Effects

1. Nourishing Kidney and Strengthening Yang: Shu Di Huang in Si Wu Tang is believed to have the effect of nourishing the kidney and enhancing yang energy. It can improve male sexual dysfunction, erectile dysfunction, premature ejaculation, and other issues. It also promotes bone growth, enhances bone strength, and can help alleviate conditions such as osteoporosis.

2. Soothing the Liver and Fortifying the Spleen: Ingredients like Bai Shao in Si Wu Tang help soothe the liver and strengthen the spleen, aiding in regulating liver qi and relieving emotional fluctuations. For individuals prone to mood changes, easily angered over minor issues, or constantly experiencing qi stagnation, Si Wu Tang can provide a certain degree of relief.

3. Beautifying the Complexion: The herbs in Si Wu Tang are mostly warming and invigorating blood agents, which help promote smooth circulation of qi and blood. Taking Si Wu Tang can improve blood circulation, alleviate cold hands and feet, make the complexion rosy, the skin smooth and elastic, thereby slowing down the aging process.

4. Regulating Menstruation and Relieving Pain: Si Wu Tang promotes blood circulation and removes blood stasis, improving symptoms of poor menstrual flow and thus regulating menstrual irregularities. It also helps relieve menstrual pain, enabling women to experience a more comfortable period.

5. Nourishing and Enriching Blood: Ingredients such as Dang Gui and Shu Di Huang in Si Wu Tang have blood-nourishing properties, which can improve conditions like menstrual irregularities and anemia caused by blood deficiency. During periods of significant blood loss such as menstruation, pregnancy, childbirth, and lactation, Si Wu Tang helps regulate blood deficiency conditions.

II. Recommended Time for Consumption

Generally, Si Wu Tang should be taken 3 to 7 days after the end of menstruation. This period is a critical phase for physical recovery and regulation, allowing full发挥 of Si Wu Tang's effects in enriching blood and regulating menstruation. It is recommended to take it one hour before breakfast, lunch, and dinner, once daily, for several consecutive days to achieve the effects of nourishing blood and qi. Women suffering from anemia, insufficient qi and blood, light menstrual flow, or delayed menstruation may start taking it on the first day after menstruation ends and continue for 3–5 consecutive days. If the purpose is to regulate menstruation or alleviate dysmenorrhea, it can be taken one week before menstruation begins, but should be avoided during menstruation itself to prevent increased bleeding.

During the period of medication, it is recommended to maintain healthy lifestyle habits, ensure sufficient sleep, improve dietary structure, adjust physical condition, and maintain overall health.
