Eucalyptus oil is one of the most commonly used essential oils. With the growing popularity of sweets and chewing gum, one of the main uses of eucalyptus oil is as a food additive. The new influence and clean appeal of synthetic fragrances has had a great impact on the cosmetics industry (such as toothpaste and oral cleaning products) and other household cleaning products, as well as the fragrance of perfumes. Eucalyptus oil is also used in the pharmaceutical industry as an antibacterial agent, especially in the treatment of respiratory infections and other similar diseases.
