This means that for any issues arising in the Spleen and Stomach, if warming the Spleen yields no results, one should promptly use Sini Decoction. Sini Decoction is a classic formula for restoring Yang, rescuing from collapse, and tonifying Kidney Yang. In Traditional Chinese Medicine (TCM), the Spleen is considered the "Foundation of Post-Natal Constitution," while the Kidney is the "Foundation of Pre-Natal Constitution." The Pre-Natal and Post-Natal are interdependent and mutually nourishing. When tonifying Spleen Yang is ineffective, one can achieve the effect of supplementing Spleen Yang by warming Kidney Yang.

Sini Decoction is composed of three medicinal herbs: Fuzi (Aconiti Radix Lateralis Praeparata), Zhi Gancao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle), and Ganjiang (Zingiberis Rhizoma). Among them, Fuzi enters the Heart, Spleen, and Kidney meridians; it functions to restore Yang and rescue from collapse, supplement fire to assist Yang, and disperse cold and eliminate dampness. It is commonly used for symptoms such as aversion to cold, cold extremities, gastric and abdominal pain, diarrhea, lower limb edema, and chest tightness. Next is Ganjiang. It is referred to in TCM as the "primary medicine for warming Yang." It is hot in nature, acrid in flavor, and enters the Spleen, Stomach, Heart, and Lung meridians. It functions to warm the middle burner and disperse cold, restore Yang and unblock the vessels, arrest vomiting, delay aging, and promote blood circulation, assisting Fuzi in replenishing the body's Yang Qi. Finally, Zhi Gancao is neutral in nature and enters the Spleen, Stomach, and Lung meridians. It functions to harmonize the middle burner, alleviate urgency, detoxify, tonify the Spleen, augment Qi, and harmonize the various herbs in the formula. Additionally, this formula is frequently used for myocardial infarction, heart failure, and dehydration caused by vomiting and diarrhea in acute gastroenteritis.

However, Traditional Chinese Medicine (TCM) requires syndrome differentiation; the best treatment is the one that suits you. Do not self-medicate blindly. If you have any health concerns, please consult a professional physician for timely diagnosis and treatment.
