Peppermint
It has a strong, agreeable odor, a pungent, aromatic taste, giving a sensation of coldness in the mouth. Its medical properties are aromatic, stimulant, and stomachic. It is much used to obviate nausea and relieve flatulent colic. The essential oil and essence are the forms in which it is employed in medicine, and they are also largely used in confectionery and cordials.
