Abstract
The invention provides herbal treatments for aged skin employing valerian extracts and other active herbal agents that are effective as relaxants. Surprisingly, mere ingestion of valerian tea on a daily basis is effective to reduce deep wrinkles. The treatments are particularly effective on persons afflicted by stress and are shown by clinical tests to reduce wrinkles and acne lesions and to improve skin texture and skin color without an increase in puffiness such as might be expected from mere hydration of the skin. The herbal agents can be administered either in a tea or a topical composition, and a combination of the two treatments is particularly effective. A preferred herbal agent is an aqueous valerian root extract. Other herbal agents include extracts of passion flower and mullein.
