Cardamom comes from seeds of ginger-family plants. People use it as a kitchen spice and in traditional herbal routines.
The seeds settle the stomach after a meal and leave your mouth feeling clean. You also get a gentle calming effect. Many rely on it for everyday oral freshness.
Stir it into food, steep it as tea, or take a measured extract or capsule. Most users time it with meals or simply whenever they need it.
Few interactions turn up. Cardamom can lower blood pressure mildly, so someone on blood pressure drugs should check with a doctor. Cooked into food, it causes almost no trouble.
