Aids in digestion
Sage tea is thought to work by stimulating the production of digestive juices and improving gut motility. It also has anti-inflammatory and antibacterial properties, which may help to reduce gut inflammation.
A small study in people with irritable bowel syndrome found that sage tea was able to improve symptoms significantly. Sage tea is generally considered safe, but it can cause side effects like heartburn and nausea in some people. If you experience any adverse effects, discontinue use and speak to your doctor.
