Most herbal teas are safe for daily consumption but can interact with certain medications or underlying health conditions. For instance, licorice root tea may elevate blood pressure and isn't recommended for individuals with hypertension.
Pregnant women should exercise caution with herbal teas, as some herbs can affect hormone levels or stimulate uterine contractions (e.g., nettle or peppermint). It's crucial to consult a healthcare provider before adding new herbal teas to your regimen, ensuring they don't interfere with your health conditions or medications.
