Medicinal and herbal teas can offer health benefits. For example, green tea, rich in antioxidants like catechins, may reduce heart disease risk by up to 31%. Peppermint tea aids digestion and may relieve irritable bowel syndrome symptoms. Chamomile tea can help improve sleep quality. However, while these teas can complement health, they should not replace medical treatments. Always consult healthcare providers before using them as remedies.
