【Formula Explanation】　

From “Formulary Studies”: The principle of this formula is to “replenish the source of fire to cultivate the primordial Yang of the right kidney”. To cultivate and tonify the primordial Yang in the kidney, one must “seek Yang within Yin”, meaning to combine Yin-nourishing and essence-replenishing ingredients with Yang-tonifying ones to achieve the effect of cultivating primordial Yang. In the formula, Cinnamon Bark, Aconite Root, combined with the ‘fleshy and affectionate’ (rich in essence) Deer Antler Gelatin, all warm and tonify Kidney Yang, replenish essence and nourish marrow. Prepared Rehmannia Root, Cornus Fruit, Chinese Yam, Dodder Seed, Goji Berry, and Eucommia Bark are all for nourishing Yin and benefiting the Kidney, nourishing Liver and tonifying Spleen. Additionally, Chinese Angelica Root nourishes blood and liver. The combination of all these herbs collectively warms Yang and benefits the Kidney, replenishes essence and nourishes blood, thereby achieving the effect of cultivating the primordial Yang in the kidney.
