Mint: A Snapshot



Peppermint is actually a hybrid of spearmint and water mint. These two mints rolled into one mean that peppermint has an extremely high content of menthol.

Due to the vitamins and nutrients it contains, peppermint has long been used for medicinal purposes. From runny noses and sore throats through to strained muscles, this handy herb has many uses. It can also be used as part of aromatherapy to reduce stress and tension.

Aside from the ubiquitous chewing gum, peppermint crops up in tea, ice cream and after-dinner mints. You’ll also find peppermint oil in a number of liqueurs where the subtle taste works wonders.

A combination of the appetizing scent and its cooling properties mean that peppermint is also a firm favorite for soaps, shampoos or body washes. It’s a staple for toothpaste and mouthwash too.

Health Benefits of Peppermint

Peppermint is often called the oldest medicine in the world and it has a wide array of proven medicinal benefits.

  • Dental Health: Whether it’s kissing goodbye to bad breath or general dental hygiene you’re after, the antiseptic properties of peppermint oil work wonders
  • Indigestion: A couple of drops of peppermint oil in some water is a wonderful way to aid digestion after eating. In some cases, it can help with Irritable Bowel Syndrome (IBS)
  • Headaches and Nausea: Popping some diluted peppermint oil on your forehead can assist with getting rid of nausea or motion sickness. Where it is both anti-inflammatory and cooling, peppermint oil can relieve headaches, even migraines
  • Stress: Stimulating your mental activity, calming and refreshing, peppermint is a natural way to  combat stress
  • Breathing: With its menthol content, peppermint is an efficient expectorant that also clears the respiratory tract. It’s present in many cold balms and rubs
  • Nail Care: Peppermint oil can help to ward off fungal nail infection
  • Pain Relief: External use of peppermint oil can help to soothe certain pains. Its cooling nature means it can reduce fever. It’s termed a refrigerant for the intensely cold sensation it provides

Spearmint is a highly aromatic herb that appears naturally.

The chief use for peppermint is culinary. As with peppermint, it’s also a common ingredient in chewing gum and toothpaste.

With a sweet and mild taste, spearmint is used widely in many medicines. Due to its relaxing effect, spearmint can also help you to relax and enjoy a good night’s sleep.

Spearmint vs Peppermint: How Do They Differ?

spearmint vs peppermint

Species and Botanical Name

Both mints are from different species. Spearmint is from the species Spicata while peppermint is Piperita.

Their specific botanical names reflect this, Metha Spicata (spearmint) and Mentha x piperita (peppermint).

Plant Facts

As mentioned, spearmint is a plant that occurs naturally whereas peppermint is a cross between species of spearmint and water mint.

The low and creeping peppermint is a real contrast with the straight and upright spearmint.

The way in which the herbs grow is also a point of difference. Spearmint will shoot up to around 3 feet in height. It will spread its way profusely and completely around the surrounding vegetation. Peppermint grows anywhere from 1 to 3 feet high. It does not spread widely, though.


While spearmint plants have pink or blue flowers, peppermint plants are crowned with purple blooms.


Spearmint plants have small leaves that grow on the branches themselves. The little leaves are slightly wrinkled.

The peppermint boasts slightly larger leaves. These grow on the stems rather than the branches. These leaves are jagged in appearance.

Menthol and Cooling Properties

It might surprise some people to know that spearmint does not contain menthol at all. It gets its cooling ability from carvone.

Peppermint, on the other hand, has plenty of menthol. This is where it derives its cooling properties from.


Spearmint has a far more delicate smell and taste than peppermint. It’s mild and somewhat sweet.

Peppermint tastes sharp and cooling while the aroma is much more intense.


The ways in which spearmint and peppermint are used is another area where they are quite different.


  • Tea
  • Mosquito repellent
  • Many therapeutic uses
  • Cocktails (mojito, mint julep)


  • Decongestants
  • Antiseptics
  • Scented oils
  • Medicinal and therapeutic properties
  • Candles
