A passage from Medicinal Plants of the Western Mountain States:

Serving as a straight–forward aromatic carminative, it relieves trapped stomach/intestinal gas and is quieting to nausea. Some also find it less harsh and more agreeable than a strong cup of Peppermint as a post–vomiting
soother. An additional plus for the gastrointestinal region is the plant’s mild to moderate anesthetic influence. After holding the strongly made tea in the mouth for 10–15 seconds a slight numbing quality should be sensed.
