Fructus lycii belongs to the Solanaceae family (solanum).

The plant is capable of tonifying yin and, correspondingly, filling out the yin of the Orbis renalis and the Orbis hepaticus and supplementing the yin.
In traditional Chinese medicine, it is frequently used to treat the following syndromes:

1. Impotence
2. Pains or weakness in the back and legs
3. Vertiginous attacks
4. General muscular weakness

Thanks to its ability to supplement yin, it is also used for the treatment of infertility for both sexes.

It is also regarded as an excellent medicine for treating diabetes mellitus.

Fructus lycii is contained in receptors such as Qui Ju Di Huang Wan or Zuo Goi Yin.
