FENNEL (Sweet) Foeniculum vulgare: This essential oil has an anise scent and flavor. One of the most important facts about Fennel is that it is anti-toxic oil. According to Patricia Davis its most valuable application is in counterbalancing alcoholic poisoning, and it has played an important part in the treatment and rehabilitation of alcoholics. It also helps with gout, arthritis etc, to prevent the build-up of toxic waste in the body which precedes the inflammatory condition of the joints. It is helpful to regularize the menstrual cycle, particularly where periods are scanty and painful with cramping pains. I use Fennel a lot for quick relief of indigestion and nausea. And it also helps to decrease the appetite!
