Effects and Use:

Internally, peppermint tea is very effective for spasms in the gastrointestinal tract, acting on smooth muscle through its essential oil. It also supports liver and gallbladder function by stimulating bile flow, easing gallbladder colic. Menthol also has antiseptic properties, aiding in cases of indigestion, nausea, and bloating.

Externally, menthol has a cooling, pain-relieving, and local anesthetic effect. It is used in sports medicine in gels, ointments, and cold sprays. Initially, menthol stimulates cold receptors, giving a cooling sensation, followed by vessel dilation and a warming effect that helps relieve pain. Menthol is also used for itching skin conditions like chickenpox, and in nasal balms and cold ointments.

Caution: Peppermint oil should not be used in pregnancy, or for infants and small children, due to risk of respiratory arrest and uterine muscle stimulation.

Tea Preparation:

Pour 150 ml boiling water over 1 tablespoon of leaves. Steep for 5–10 minutes, strain.

Drink 2–4 cups daily.
