An improved St. John's Wort-based herbal composition for promoting emotional health in animals, preferably humans, contains a St. John's Wort supercritical extract composed of highly stable hyperforins and rich in essential oil and other components typically found in St. John's Wort extracts. The hyperforin-containing extract is obtained by a supercritical extraction process involving subjecting the St. John's Wort herb to high pressure extraction using compressed gas, most preferably compressed carbon dioxide gas. By using this particular supercritical extraction process to obtain the hyperforin-containing extract, the hyperforins in the extract will be more stable than in extracts retrieved by conventional extraction processes such as processes using water and alcohol. Methods for using the herbal composition to promote emotional health in animals, preferably humans, involve orally administering the composition.
