In fact, aromatherapy is the use of flavorings extracts of plants (or essential oils) for medical purposes.
These essential oils are used primarily for healing of wounds, burns, skin diseases, and also to treat psychological illnesses with massages, baths ...

For example, Tea Tree was discovered to have antimicrobial effects, that's why it can be used in creams and facial washes as a treatment for acne. Also, there's peppermint and camphor which are, when used, could clear a runny nose using an inhaler.
