This sunny herb is known for easing depression, but can do so much more! St. John’s is helpful for anxiety (especially when it manifests with stomach unease), insomnia, and fear. It is also useful for cases of nerve pain or nerve damage. It has anti-viral properties useful for shingles, herpes, chicken pox, and hand foot and mouth. It is a powerful liver cleanser and therefore should not be used in combination with pharmaceutical drugs that need to stay in the body long-term.
