St John’s Wort

(Hypericum sp.)

Numerous studies suggest that St. John's Wort extract (hypericum extract), when standardized for hypericin and hyperforin, helps to balance serotonin levels and maintain normal neurotransmitter activity to promote emotional well-being and a positive mood.

This is one of the few herbs that has made it through the restrictive new EU directives, and so branded versions will remain available (although prices are likely to rise sharply).
