Color enhanced scanning electron micrograph (SEM) of common St. John's wort (Hypericum perforatum), of the Clusiaceae family. The top surface of a leaf with recesses can be seen. Leaves appear to have holes due to a layer of colorless essential plant oils and resin. St. John's wort is used in herbal medicine to treat moderate depression, nerve pain, sleep disorders, anxiety, and as a balm for wounds, burns, and insect bites. Magnification 880x
