Peppermint

Mentha × piperita

Leaf · cooling · dispersing

The lift in the cupboard — head, belly, and a closed room.

On the nose

How it smells

Cool, fresh, mentholated, and penetrating, with herbal-green notes. Sharp and clean. The steam is half the plant.

More mint-cool

In the mouth

How it tastes

Cooling, refreshing, classic mint. Sharper and more mentholated than spearmint.

Traditional use

Peppermint is pungent more than sour, but in this kitchen map it does air’s work: it lifts, cools, and moves. Folk use trusted it for a gassy belly, a tight brow, and a feverish restlessness. The steam is half the medicine.

In the cup

A small handful fresh or 1 tsp dried, covered steep 5–7 minutes. Oversteeping turns harsh. Culinary: peas, lamb, chocolate, lemonade.

From the receipt book

Head, cramp, and sinus cup

1 teaspoon dried peppermint — or a sprig of fresh — to a cup of hot water. The same tea was used for muscle cramp and to open a tight sinus.

Nervous headache

Peppermint with skullcap and sage.

Blood

Sour blood · sour

Sour is cooling and astringent. It draws and binds, thickens thin blood, starts saliva, and hydrates even as it tightens. Sour plants carry the antioxidants of fruit. They move mucous and support the lungs — large doses irritate. Lemon-family plants show up again and again in sinus cups.

The promise

A careful hand

Ordinary tea for a healthy adult.

Extremely common and safe as tea. Can relax the upper gate of the stomach and worsen heartburn in some people. Ordinary tea amounts in pregnancy are generally fine. The concentrated oil is another story.
