Lemon oil is an essential oil that is extracted from the rind of the lemon fruit. It has a fresh, citrusy, and uplifting aroma that is believed to be energizing and invigorating. The oil is commonly used in aromatherapy and is believed to have a number of therapeutic properties, such as being an astringent, detoxifying, and a digestive aid. It is also used to help with skin conditions such as acne and oily skin. Lemon oil is commonly used to help with stress, anxiety and other emotional issues. It can also be used as a natural cleaning agent, and can help remove grease and grime from surfaces. It is considered safe for most people, but it can be phototoxic, meaning that when applied to the skin and exposed to sunlight, it can cause skin reactions such as pigmentation and burns. It should be used with caution and diluted before topical use.
