Aromatherapy is the use of scents that come from plant materials and fragrant plant oils, especially essential oils, to improve psychological and or physical well-being. It is widely believed that inhaling the aroma of essential oils stimulates brain functions and has an effect on your feelings and moods. Additionally, the skin can absorb essential oils and they travel through the bloodstream to promote the healing of the entire body. This form of therapy is gaining momentum as a way of alternative medicine. Some of its applications include pain relief, increased cognitive function and mood enhancement. Aromatherapy can be done as a complementary therapy, which is offered alongside standard treatment or as a form of alternative medicine, which is offered instead of conventional treatments. Aromatherapists, who specialize in aromatherapy and its practice, use mixtures of therapeutic essential oils that can be delivered through massage, inhalation topical application, or water immersion in order to elicit a desired response.
