Lemon has a fresh, uplifting, and citrus-y aroma. It is a pleasant and functional addition to cleaning formulations and air fresheners due to its disinfectant, antiviral, antibacterial and antiseptic properties. It helps to clean and cut grease and stains and remove gum while imparting a pleasant citrus aroma. It also helps improve micro-circulation, immune function, and helps with digestive problems. For hair and skincare formulations, the astringency of Lemon makes it useful for combating oily skin and hair. Within holistic aromatherapy, the bright, citrus scent is stimulating, but it also is said to aid in focus and concentration. It is often used by spas and incorporated into body massage oils, body wraps and salt soaks.
