Fructus cornii belongs to the Cornacea family (dogwood plants)

Thanks to its ability to tonify the Orbis renalis and the Orbis hepaticus, it is used in traditional Chinese medicine for the treatment of

1. Dizziness
2. Tinnitus
3. Impotence
4. Pains in the lumbar spine and the knees
5. Pollakiuria

Its sour and astringent taste helps to preserve the yin and counteract severe losses of bodily fluids. It can therefore be used most beneficially to treat enuresis, sweating and excessive micturition.
The remedies for which it is used include Liu Wei Di Huang Wan.
