St Johns Wort (Hypericum perforatum) is a common plant that has been used for its health benefits for centuries. It is believed to have originated in Turkey, but has spread virtually world wide, and is particularly well-known in England. The use of St. John’s wort dates back to the ancient Greeks. Hippocrates recorded the medical use of St. John’s wort flowers. St. John’s wort was given its name because it blooms about June 24th, the birthday of John the Baptist. It has significant healing power and was used to heal sword wounds. An oil can be made from St. John’s wort. Some people apply this oil to their skin to treat bruises and scrapes, inflammation and muscle pain, burns, wounds, bug bites, hemorrhoids, and nerve pain. But applying St. John’s wort directly to the skin is risky. It can cause serious sensitivity to sunlight.
