A distilled drink or liquor is an alcoholic drink produced by distilling (i.e., concentrating by distillation) ethanol produced by means of fermenting grain, fruit, or vegetables. Unsweetened, distilled, alcoholic drinks that have an alcohol content of at least 20% ABV are called spirits.
In aromatherapy, inhaling the aroma of grapefruit essential oil (or absorbing grapefruit essential oil through the skin) is thought to transmit messages to a brain region involved in controlling emotions. Known as the limbic system, this brain region also influences the nervous system.
In addition to limonene, grapefruit essential oil contains other powerful antioxidants, including vitamin C, myrcene, terpinene, pinene and citronellol. Most commonly, grapefruit oil is used to fight throat and respiratory infections, fatigue, muscle aches, as well as a natural remedy for arthritis.
