1. Prescription Source & History

1. Origin Background

Taohong Siwu Decoction originated from ancient classic medical books, and its emergence is closely related to the in-depth research and clinical practice of traditional Chinese medicine on the theory of qi and blood. Traditional Chinese medicine believes that qi is the commander of blood, and blood is the mother of qi. Qi and blood depend on each other and interact with each other to jointly maintain the normal physiological functions of the human body. When there are problems with qi and blood, various diseases will occur. Taohong Siwu Decoction is an effective prescription created for qi and blood stagnation, blood stasis blockage and other conditions.

Sini Decoction is a classic prescription for nourishing and enriching blood in traditional Chinese medicine, composed of four herbs: Rehmanniae Radix Praeparata, Angelicae Sinensis Radix, Paeoniae Radix Alba, and Chuanxiong Rhizoma. With the accumulation of clinical experience, doctors found that the simple blood-nourishing prescription had poor effects on some patients with blood stasis symptoms. Therefore,桃仁 (Taoren) and 红花 (Honghua) were added to Sini Decoction to form Taohong Siwu Decoction. Since then, through the clinical application and continuous improvement of doctors in each generation, its curative effect has been widely recognized, becoming one of the commonly used prescriptions for promoting blood circulation to remove blood stasis in traditional Chinese medicine, and has been passed down to this day, playing an important role in traditional Chinese medicine clinical practice.
