The intense refreshment for body and mind

What is peppermint?

Peppermint is an aromatic plant from the mint family (Lamiaceae), which also includes rosemary, sage and basil. It is a hybrid of water mint and spearmint and is known for its particularly intense, slightly sharp flavour. The characteristic cool sensation in the mouth is due to the menthol it contains, which also gives peppermint its refreshing quality.

This perennial, herbaceous plant grows up to 90 centimetres tall and has elongated-oval, toothed leaves covered with fine hairs. Leaf colour varies by variety from light green to dark green and sometimes with reddish tones. From early summer – roughly June to September – it displays its flowers, which range in colour depending on the variety from white through pink to violet.

Peppermint is used both fresh and dried in many ways, especially in beverages like teas or in blends with other herbs and fruits. Due to its strong scent, it is also a popular garden plant for both appearance and aroma.

Which active compounds are found in peppermint?

Peppermint is characterised by a variety of valuable constituents, concentrated mainly in the essential oil. This oil is predominantly found in the leaves. Steam distillation is used to extract the oil. Approximately 50 kilograms of dried leaves are required to obtain one kilogram of concentrated plant extract. The extract content in the leaves is about two percent.

The most important components of the oil include menthol, menthol esters, menthone and menthofuran. Menthol in particular is present in high concentrations (30–55%) and defines the characteristic scent. These substances belong to the volatile components that contribute significantly to the oil's effectiveness.

The leaves of peppermint also contain numerous secondary plant compounds with health-promoting properties. These include phenolic compounds such as rosmarinic acid and a variety of flavonoids, including eriocitrin, luteolin and hesperidin. These compounds are known for their antioxidant and anti‑inflammatory properties.

In addition, the leaves contain bitter compounds, tannins and triterpenes, traditionally associated with digestive and astringent effects. The range is rounded out by vitamins and trace elements present in small amounts, which contribute to the plant's overall effect.

Effects: how healthy is peppermint?

Peppermint is a versatile plant that has positive effects on several areas of health. It is particularly known for its relaxing effect on the muscles of the gastrointestinal tract. It is therefore a proven remedy for complaints such as bloating, nausea or a feeling of fullness. Its soothing properties also promote bile flow and thus support digestion, especially after fatty meals.

Scientific studies also show that peppermint can have pain‑relieving effects, for example for menstrual pain or muscle aches. Peppermint can also relieve mild respiratory conditions, as its constituents help loosen mucus and make breathing easier.

Peppermint tea offers antioxidant and anti‑inflammatory benefits that help protect the body from oxidative stress and strengthen the immune system. Early research even suggests a protective potential for the nervous system, which could help in the long‑term prevention of neurodegenerative diseases.

Another positive aspect is peppermint's invigorating and refreshing effect, which can benefit circulation and general wellbeing. It also has a pleasant aroma that freshens the breath and can encourage daily fluid intake – all without sugar or caffeine.

What is the difference between mint and peppermint?

The difference between mint and peppermint lies mainly in their botanical origin and aroma. The term “mint” covers a whole genus with numerous species and subspecies – including water mint, field mint or spearmint – whereas peppermint (Mentha × piperita) is a specific hybrid resulting from the crossing of different mint species.

They also differ markedly in taste: peppermint, with its high menthol content, has an intense, cool‑sharp flavour that sets it apart from other mint varieties. Its typical “peppery” character makes it popular both in cooking and as a medicinal herb. Other mint species such as spearmint taste noticeably milder and sweeter.

Visually the two are often hard to distinguish, as they share many common features such as toothed leaves and similar growth habits. The real difference therefore only becomes apparent on closer inspection or by tasting.

What are the benefits of peppermint essential oil?

Peppermint extract offers numerous benefits, particularly for skin and hair as well as overall wellbeing. One of its main properties is the anti‑inflammatory effect, mainly attributed to constituents such as menthone and the cooling action of menthol. These substances can inhibit certain inflammatory mediators in the body and at the same time act as analgesics by modulating the transmission of pain signals.

Its antimicrobial efficacy is also notable: certain active compounds disrupt bacterial cell membranes, making survival more difficult. This property can be useful for caring for problematic skin, for example with bacterial blemishes. Additionally, the plant compound shows fungicidal effects against certain fungi by attacking their cell structure, making it interesting for adjunctive treatment of fungal skin issues such as dandruff.

Another potential application is the antiviral effect: studies indicate that certain concentrations of the oil can inhibit the replication of herpes viruses. Furthermore, peppermint oil appears to positively affect hair growth. Experiments have shown that it stimulates hair follicles, prolongs the growth phase and makes hair appear fuller. Mechanisms involved include the promotion of cellular growth processes and activation of certain enzymes in the scalp.

Peppermint oil for headaches: can it really help?

Peppermint oil has proven effective in the relief of headaches, particularly tension‑type headaches. Several scientific studies show that its effect is comparable to common painkillers.

The pain‑relieving effect is mainly attributed to the cooling plant compounds. When the extract is applied to the forehead and temples, these compounds activate cold receptors in the skin. This produces a cooling stimulus that promotes blood circulation and can relieve muscle tension in the head area. In addition, these substances inhibit the activity of certain mediators involved in pain transmission.

Peppermint oil can also be potentially helpful for migraine. It can play a supportive role both for acute attacks and for recurrent headaches. Proper application is particularly important: it should be applied diluted and ideally used twice at 15‑minute intervals to achieve the best possible effect.

How to use peppermint: useful tips

• Prepare a classic peppermint tea: pour 1.5–3 g of chopped leaves with hot water and let the tea steep covered for five to ten minutes. This allows the aroma to develop optimally.
• Drink peppermint tea not only warm but also as a refreshing cold beverage: let fresh organic mint sprigs infuse in cold water – ideal for hot summer days.
• If you suffer from bloating or cramp‑like discomfort, combine peppermint with other medicinal plants such as chamomile, fennel or caraway to enhance the effect.
• Avoid applying undiluted peppermint oil to sensitive skin, as it can cause irritation. Always dilute it with a carrier oil, for example almond or olive oil.
• Tension headaches can be alleviated with a stimulating head massage in which you massage peppermint oil into the scalp and then follow up with cold (for example ice cubes).
• For a blocked nose, inhale a drop of peppermint oil over a bowl of hot steam to clear your airways. Pay attention to the correct temperature to avoid scalding.
• For colds, use an essential oil blend containing peppermint, cypress, niaouli and cardamom, suitable for rubbing in and for full baths.
• Boost your oral hygiene with a homemade peppermint mouthwash. It has antibacterial effects and provides fresh breath – ideal after brushing your teeth.
• Use peppermint to flavour drinks or sweets by stirring a drop of the concentrated plant extract well diluted (for example dissolved in honey or syrup) into small portions. This is ideal for cocktails, lemonades or mint chocolate.
• Peppermint is also suitable for savoury dishes. It can be used in sauces and curries as well as in dishes with poultry, lamb, legumes and vegetables.
• Use peppermint oil as a natural mosquito repellent: apply a few drops of the diluted oil to your skin or clothing. It acts as a deterrent to insects.
• For sunburn, cool compresses with cold peppermint tea or diluted peppermint oil help to cool the skin pleasantly and reduce tightness.
• If you want to dry peppermint yourself, use the flowers, roots and leaves of the plants – whether from your own garden or purchased – and store them in a dark, dry place so that the aroma and active substances are preserved.
• Avoid peppermint in certain conditions such as biliary disorders or asthma, as its constituents can, in isolated cases, worsen symptoms. Seek medical advice if in doubt.
