People have been drinking tea to help treat digestive issues and other illnesses for thousands of years.
Several herbal teas have been shown to help with nausea, constipation, indigestion, and more. Fortunately, most of them are widely available and easy to make.
Peppermint, a green herb from the Mentha piperita plant, is well known for its refreshing flavor and ability to soothe an upset stomach.
Animal and human studies have shown that menthol, a compound in peppermint, improves digestive issues
Peppermint oil is sometimes used to improve irritable bowel syndrome (IBS), an inflammatory condition that affects the large intestine and can cause stomach pain, bloating, gas, and other unpleasant symptoms
A 4-week study in 57 people with IBS found that 75% of those who took peppermint oil capsules twice per day reported improvements in symptoms, compared with 38% of those in the placebo group
Peppermint tea may provide benefits similar to those of peppermint oil, although the tea’s effects on human digestion have not been studied
Ginger, scientifically known as Zingiber officinale, is a flowering plant native to Asia. Its rhizome (underground part of the stem) is popularly used as a spice worldwide.
Compounds in ginger, known as gingerols and shogaols, can help stimulate stomach contractions and emptying. Thus, the spice may help with nausea, cramping, bloating, gas, or indigestion
A large review found that taking 1.5 grams of ginger daily reduced nausea and vomiting caused by pregnancy, chemotherapy, and motion sickness
Another study in 11 patients with indigestion found that taking supplements containing 1.2 grams of ginger significantly shortened stomach emptying time by nearly 4 minutes, compared to a placebo
