Fennel has through history been considered an appetite depressant, and as such, a weight loss aid.  All parts of the Fennel plant are safe for use, and Hippocrates recommended a Tea to increase the flow of milk in nursing mothers.  Menopausal women may want to try it to ease the associated symptoms.  The leaves or stems can be pounded into a paste and given to nursing mothers to relieve breast swelling.   

Fennel Teas, or Fennel Water have been used throughout history to break up kidney stones, quiet hiccups, prevent nausea, aid digestion, prevent gout, purify the liver, reverse alcohol damage to the liver, and treat jaundice.  For babies, it is said to to relieve colic and flatulence, and to expel worms. It may be effective when used along with conventional treatments in prostate cancer (and it is definitely worth trying, but consult with your doctor first).  The tea can also be gargled as a breath freshener and applied as an eye wash.  Alternatively, the leaves can be dried, pulverized into a powder, and made into Capsules for when it's not convenient to utilize a tea.

To make Fennel water, use 8 drops of Oil to 1 pint of water - take up to 8 teaspoons per day.  

Fennel is disliked by fleas, and can therefore be used around the house in doorways and near pet bedding to reduce flea populations.  

Fennel is a cleansing and medicating herb, and can be used for a steam facial for opening pores and rejuvenating facial skin.
