Peppermint tea, brewed from the plant's leaves, is among the most popular herbal teas worldwide. Renowned for its health benefits, it is particularly beneficial for individuals experiencing headaches, sinus issues, or stomach discomfort. Rich in flavonoids, a single bag of peppermint tea provides a significant dose of antioxidants. Additionally, it has a soothing effect on smooth muscle tissue and can help ease a sore throat.  
 
Caution: Peppermint tea may reduce esophageal sphincter pressure and should be used carefully by individuals with gastroesophageal reflux (GERD) or a hiatal hernia. It is also advised to use caution if you have gastrointestinal ulcers or significant inflammation of the gastrointestinal tract.
