Hypericum Perforatum extract is prepared from a flowering plant species of the genus hypericum. Hypericum Perforatum extract, also known as St John's wort extract, is a secure nerve nutrient. It has been used to treat mild to moderate depression, anxiety, or sleep disorder. It also has significant effects on anti-DNA and RNA virus, directly acting on bird flu, swine fever and foot-and-mouth disease to stop the replication and reproduction of the virus and to strongly inhibit the virus.

The active ingredient hypericin can treat moderately depressed patients without side effects and is also anti-tussive, analgesic and hepato-protective.
