Peppermint: The Plant, Foraging and Kitchen Guide, Teas.co.uk

Peppermint (the plant), in summary: Peppermint (Mentha x piperita) is a watermint-spearmint hybrid; very easy to grow, classic Black Mitcham English cultivar, menthol provides cooling.

Last reviewed by the teas.co.uk team in May 2026.

Peppermint is the menthol rich hybrid of watermint and spearmint, the medicinal mint, the IBS evidenced mint, the post meal mint. It's been cultivated across Europe and North Africa since at least the 18th century, and the UK has its own peppermint growing tradition (Black Mitcham peppermint from Surrey is historically renowned).

The plant

Peppermint (Mentha piperita) is a hybrid that arose in 17th century England between watermint (Mentha aquatica) and spearmint (Mentha spicata). The hybrid produces:

Higher menthol content than parent species (40-50% of essential oil)
Sharper cooling sensation
Stronger traditional uses

The famous Black Mitcham variety from Surrey was particularly highly regarded historically. Modern peppermint is grown commercially across Europe, the US (Pacific Northwest especially), India, and other regions.

The cooling sensation explained

Menthol triggers cold sensing receptors (TRPM8) in the mouth, throat, and skin without actually lowering temperature. This produces the distinctive "cooling" sensation that defines peppermint. The same receptors respond to actual cold; menthol "tricks" them.

Beyond the cooling, menthol has:

Antispasmodic effects on intestinal smooth muscle
Antibacterial properties
Mild analgesic effects (cooling reduces pain perception)
Decongestant effects (opens nasal passages)

The Black Mitcham heritage

Mitcham, Surrey was historically the centre of UK peppermint production from the 18th to mid-20th century. "Black Mitcham" peppermint was renowned for its high quality essential oil and was exported globally. Most UK peppermint production has since moved abroad, but the Black Mitcham name persists as a quality marker for some products.
