The kidney is the foundation of innate constitution and governs the storage of essence. This essence nourishes the limbs and fills the nine orifices. When kidney essence is insufficient, the body's limbs lose their nourishment, leading to aging and exhaustion. Symptoms such as loose teeth, premature graying of hair, soreness and weakness in the waist and knees, and a pale tongue with little coating indicate that it is time to tonify the kidneys. Today, I will teach you about four herbs to replenish kidney essence, secure the essence, and balance Yin and Yang.

The first herb is Oyster Shell (Muli). Oyster shell has an astringent effect, which can secure and protect the essence-qi, preventing it from leaking out.

The second herb is Rosa laevigata (Jinyingzi). It has a sour flavor, and since sourness possesses astringent properties, it can consolidate and preserve the body's vital essence.

The third herb is Poria cocos (Fuling). Poria enters the heart, lung, spleen, and kidney meridians; it functions to promote diuresis, drain dampness, strengthen the spleen, harmonize the stomach, and calm the mind.

The fourth herb is Cuscuta seed (Tusizi), which can balance and tonify both Yin and Yang. In addition to relying on the spleen's transport and transformation functions, the kidneys also depend on the warming effect of kidney Yang. Cuscuta seed is capable of both tonifying kidney Yang and benefiting kidney essence.

When these four herbs are used together, they tonify the kidneys and essence while balancing Yin and Yang. By providing regulation from multiple angles simultaneously, they improve the symptoms of kidney essence deficiency.

A reminder to everyone: Traditional Chinese Medicine requires syndrome differentiation. If needed, please consult a professional physician for timely diagnosis, treatment, and conditioning.
