Learning About Aromatherapy
What Are Essential Oils?
Essential oils are made from flower, herb, and tree parts, like bark, roots, peels, and petals. The cells that give a plant its fragrant smell are its "essence." When an essence is extracted from a plant, it becomes an essential oil.
It takes a lot of plant product to make essential oils. More than 200 pounds of lavender flowers are used to make just 1 pound of lavender essential oil.
Not all products made with plant essence are essential oils. True essential oils aren't blended with other chemicals or fragrances. They're made using a specific process that doesn't change the chemistry of the plant.
Lemon, chamomile, lavender, cedarwood, and bergamot are a few of the essential oils used regularly in aromatherapy.
How Aromatherapy Works
Experts think aromatherapy activates areas in your nose called smell receptors, which send messages through your nervous system to your brain.
The oils may activate certain areas of your brain, like your limbic system, which plays a role in your emotions. They could also have an impact on your hypothalamus, which may respond to the oil by creating feel-good brain chemicals like serotonin.
Some experts think that when you put essential oils on your skin, they cause a response in your skin and other parts of your body, like your joints.
