2. Fennel Oil for Digestive Issues
Fennel oil has long been administered to soothe various digestive woes—including bloating, gas and menstrual cramps, heartburn, and even colic in infants. The native Mediterranean herb is often confused with anise. However, even though they taste and smell similar to licorice, they are not the same.
The fennel plant is used as a medicinal oil after the yellow flowers are dried into seeds. According to research from the NYU Langone Medical Center, fennel seeds stimulate the flow of bile as they relax digestive and abdominal muscles, thus reducing pain and easing digestion.
