Foeniculum vulgare. A sweet, anise-flavored member of the carrot family. The seeds have been chewed after meals for centuries to ease gas.
What the research supports
A fennel seed oil emulsion reduced infant colic in a 2003 placebo-controlled trial. In adults with IBS, a curcumin and fennel essential oil combination improved symptoms and quality of life over 30 days. Fennel is also part of many traditional multi-herb digestive formulas.
The dose that was actually studied
The adult IBS trial used a combination capsule with fennel essential oil. Fennel seed tea, typically 1 to 2 teaspoons of crushed seed per cup, is the common traditional use.
