Did you know?

Plants store essential oils either in external secretory structures, which are found on the surface of the plant, or internal secretory structures, which are found inside the plant material. In plants that have an external secretory structure you just have to lightly touch them and the aroma will be imparted on to your skin whereas in plants with internal secretory structures you may need to break the leaf or seed in order to get to the aroma/essential oil.
