Detailed Explanation of Main Efficacy and Functions

1. Tonifying the Liver and Kidneys, Improving the Root Cause of Deficiency: Cornus officinalis has a sour and astringent taste, is slightly warm in nature, and enters the liver and kidney meridians. It can balance yin and yang, nourishing both liver and kidney yin while warming and assisting kidney yang, making it an essential medicine for treating liver and kidney deficiency. It has a good effect on improving symptoms caused by liver and kidney insufficiency, such as lower back and knee weakness, dizziness, tinnitus, blurred vision, impotence, and seminal emission. It is often combined with Rehmannia glutinosa and Dioscorea opposita, such as in the classic formula Liuwei Dihuang Wan, to synergistically enhance the kidney-tonifying effect.

2. Astringent and Consolidating, Retaining Essence and Body Fluids: This is another core function of Cornus officinalis, manifested in several aspects:

3. Astringent and Stopping Nocturnal Ejaculation: For seminal emission, spermatorrhea, and premature ejaculation caused by kidney qi deficiency, it can consolidate kidney essence and reduce abnormal loss.
