Icariin has the effects of increasing cardiovascular and cerebrovascular blood flow, promoting hematopoietic function, immune function, and bone metabolism, as well as tonifying the kidney and strengthening yang, anti-aging, and anti-tumor.

1. Endocrine function: icariin can promote sexual function due to the hypersecretion of semen. After the seminal vesicle is filled, it stimulates the Sensory nerve and indirectly excites sexual desire.

2. The impact on immune system function: The number of T cells, lymphocyte conversion rate, antibodies, antigens, and phagocytic function of the reticuloendothelial system in patients with kidney deficiency are low, but can be improved after treatment with kidney tonifying drugs such as Epimedium.
