Citronella oil also has a few other uses. It is sometimes used in aromatherapy for its uplifting and refreshing fragrance, believed to have mood-enhancing and stress-relieving effects. It is also used in the cosmetic industry as an ingredient in perfumes, soaps, and other personal care products. Citronella oil should be used with caution. It is generally considered safe for topical use when diluted in a carrier oil, but direct application to the skin may cause irritation or allergic reactions in some individuals. It is recommended to perform a patch test before using citronella oil on the skin and to follow the instructions and precautions provided by the product manufacturer.
