Chemistry - Plants Produce Essential Oils
Mother Nature. She does the difficult work. Humans - we do the farming, gathering, and distilling.
This micrograph shows the very small cells that produce and store essential oils. They are called Trichomes (pronounced TRI-combs).
Simply touching a Trichome cell will release the essential oils. When you touch an aromatic plant (like lavender, spearmint, peppermint, oregano, thyme, rosemary, etc) some of the essential oil is released from the Trichomes. You can smell the oil on your hands. You can smell it in the air.
EXPERIMENT: Go to a store or greenhouse. Touch the growing herbs or aromatic plants. What do you experience?
Trichomes generally grow on the surface of the plant stem and leaf. Plants use essential oils for survival. Their goal is to produce seed and get their seeds dispersed in the environment. Essential oils help plants survive so they can disperse their seeds.
