People who suffer from conditions such as GERD (gastroesophageal reflux disease), hiatus hernia, kidney stones, or heartburn should avoid drinking mint tea. This is because peppermint tea, which is a type of mint tea, can worsen the symptoms of these conditions. Peppermint has a relaxing effect on the muscle that separates the esophagus from the stomach, known as the lower esophageal sphincter. If this muscle is weakened or relaxed, it can allow stomach acid to flow back up into the esophagus, causing acid reflux or heartburn.

Similarly, for individuals with a hiatus hernia, which occurs when a part of the stomach pushes up into the chest through a small opening in the diaphragm, consuming peppermint tea can exacerbate the symptoms. The relaxation effect of peppermint on the lower esophageal sphincter can further contribute to the reflux of stomach acid into the esophagus.
Moreover, individuals who have kidney stones should also avoid mint tea. Peppermint tea contains compounds called oxalates, which can contribute to the formation of kidney stones. Oxalates are substances that bind with calcium in the urine, forming crystals that can accumulate and eventually lead to the development of kidney stones.
Lastly, some medications may interact negatively with peppermint, so it is advisable to double-check with a healthcare professional if you are taking any medications before consuming mint tea.
In summary, people with GERD, hiatus hernia, kidney stones, heartburn, or those taking certain medications should avoid drinking mint tea, particularly peppermint tea, as it can worsen their symptoms or potentially interact with medications.
