Fennel is flavorful herb with a similar aroma to the anise plant. The alkaline herb is an aromatic plant used traditionally for both medicinal and culinary purposes. Historically, the herb was used as a common remedy for a variety of digestive ailments. The herb helped to relieve constipation, relieve flatulence, improve the appetite, aid in bloating and indigestion and to work as a laxative.
Now, scientific research is confirming that drinking fennel tea does in fact, help to relax the muscle in the intestines and relieves constipation.
Several research studies support the use of fennel as a treatment for constipation. An article in the “International Journal of Food Sciences and Nutrition” claimed that fennel increased gastric motility in a few animal tests, reducing the time that food passes through the digestive system by 12 percent.
In a placebo-controlled study reported in “BMC Complementary & Alternative Medicine,” participants with chronic constipation consumed the herb fennel for five days and improved their colonic transit time and number of bowel movements. The study’s researchers concluded that fennel has a laxative effect and is a safe option for the treatment of constipation.
Besides digestion, the plant also can be used to to treat glaucoma, hypertension, relieve colic in infants, to increase the milk supply of breast-feeding mothers.
