Si Wu Tang, or "Four-Substance Decoction," is a renowned herbal remedy in Traditional Chinese Medicine (TCM), cherished for centuries for nourishing blood and regulating menstruation. Its classic recipe, rooted in the Tang Dynasty, combines four core herbs in a simple yet precise formulation.
To prepare Si Wu Tang, you will need 15 grams each of *Shu Di Huang* (Rehmannia root, prepared), * Bai Shao* (White Peony root), *Dang Gui* (Angelica sinensis), and *Chuan Xiong* (Lovage root). Begin by soaking the herbs in cold water for 30 minutes to rehydrate them. Then, place them in a clay or ceramic pot with about 600ml of water. Bring to a boil, then reduce heat to a simmer. Cover and let it cook for 1–2 hours, until the liquid reduces to approximately 200ml. Strain the decoction and discard the herbs. For enhanced flavor, a small piece of fresh ginger or a few red dates may be added during simmering.
This golden-hued elixir is typically consumed warm, once or twice daily. Its balanced formula gently invigorates blood, alleviates menstrual discomfort, and addresses symptoms like pale complexion or fatigue. As a foundational tonic, Si Wu Tang embodies TCM’s wisdom of harmony and natural healing, remaining a timeless remedy for blood nourishment.
