When taken internally， lemon myrtle (Backhousia citriodora) boosts the body’s natural defenses* and can also be used as a cleansing agent to purify household surfaces. Aromatically， lemon myrtle has a powerful lemon scent， even stronger than lemon essential oil. The fresh aroma is uplifting and refreshing， which may help clear the mind to enhance concentration or promote a peaceful night’s sleep.
