使用
palmarosa oil (Cymbopogon martini) is attributed with soothing, moisturizing, anti-septic, tonic, and cell-regenerating properties. Palmarosa oil is said to have an immediate calming and refreshing effect on the skin. It is indicated for acne skin and dermatitis as well as for dry skin. This oil is widely used in perfumery and cosmetology because its fresh, rose-like scent makes it useful for the adulteration of rose oil, one of the most expensive essential oils. It can also be used to mask odors. Palmarosa oil is obtained by distillation of this flowering grasslike plant.
