Boil the water in a kettle or saucepan.

Add the dried peppermint leaves, chamomile flowers, and lavender flowers to a teapot or a heat-resistant container.

Pour the boiling water over the herbs in the teapot.

Cover the teapot and let the tea steep for approximately 10 minutes.

Strain the tea into a cup using a fine mesh strainer or tea infuser.

Add honey or lemon, if desired, for taste.

Stir the tea gently and allow it to cool slightly before drinking.

Sip the tea slowly and enjoy its soothing effects.
