The Mint (Pudina) Plant Explained

Mint (genus Mentha), known in Hindi as pudina, is a group of fragrant, creeping perennial herbs of the Lamiaceae family whose leaves are used fresh in chutneys, raitas and drinks and whose oil is extracted commercially for menthol. In India, the word pudina usually means garden mint or spearmint grown in kitchen gardens and markets, while a separate field crop, Japanese mint (Mentha arvensis), is grown on a large scale for mentha oil.

India is one of the world’s leading producers of mentha oil and menthol crystals, and mint is also one of the easiest herbs to grow in a pot at home. This article explains what mint is, how its main species differ, where and how it is cultivated in India, and how it is used in food, industry and daily life.

Mint Quick Facts

Key Takeaways

• Mint is a perennial herb of the Lamiaceae family that spreads by creeping stems called runners or stolons and has square stems and oppositely arranged leaves.
• Pudina in Indian kitchens is usually spearmint or garden mint, while commercial field mint (Mentha arvensis) is grown for menthol-rich oil.
• India is among the world’s largest producers of mentha oil, with Uttar Pradesh the main growing state.
• Menthol, the main component of field mint oil, produces a cooling sensation by activating cold-sensing nerve receptors rather than by lowering actual temperature.
• Peppermint is a naturally occurring hybrid of watermint and spearmint and is generally sterile, so it spreads only by cuttings and runners.
• Mint grows readily in pots and moist shade, and it is best grown in a container because its runners spread aggressively.

What Is Mint and What Does the Plant Look Like?

Mint is a low, spreading herb with square stems, opposite pairs of toothed, aromatic leaves and underground and surface runners that root wherever they touch moist soil. The leaves contain oil glands that release a cool, sweet scent when crushed.

The plant belongs to the Lamiaceae family, which also includes tulsi (holy basil), basil, rosemary, sage, thyme, oregano and lavender. A square stem and paired leaves are characteristic features of the family. Mint produces small whorled clusters of pale purple, pink or white flowers that attract bees and butterflies.

Most mint grows between 30 and 90 cm tall, depending on species and conditions. Many mints do not set viable seed and are reproduced from cuttings or runners rather than seeds.

• Stem: square, often reddish or green, branching at the base.
• Leaves: oval to lance-shaped with serrated edges, in opposite pairs.
• Spread: by runners that form dense patches, which is why mint is considered invasive in open garden beds.
• Preference: moist, fertile soil and light shade to partial sun.

What Are the Main Types of Mint?

The main types of mint are spearmint (Mentha spicata), peppermint (Mentha x piperita), field or Japanese mint (Mentha arvensis) and watermint (Mentha aquatica), and they differ in flavour, oil composition and use. In Indian homes and markets, spearmint and field mint are the types most often encountered.

The CSIR-Central Institute of Medicinal and Aromatic Plants (CIMAP) in Lucknow has released improved mint varieties for Indian conditions, including field mint cultivars such as Kosi, Kushal and Himalaya, which are known for good oil yield. Some mint varieties are named differently by region, and the market name pudina covers several species.

Where Is Mint Grown in India?

Mint is grown across India in kitchen gardens and small market farms, and commercial mentha production is concentrated in Uttar Pradesh, particularly the districts around Barabanki, Bahraich, Sitapur, Lucknow, Rampur, Moradabad, Badaun and Bareilly. Smaller areas are cultivated in Punjab, Uttarakhand, Haryana, Bihar and Madhya Pradesh.

The Indo-Gangetic plains suit field mint because of their deep alluvial soils, irrigation availability and warm spring and summer. India became a major player in the global mentha oil trade from the 1970s and 1980s onward after Indian scientists introduced and improved Japanese mint, and it is generally counted among the leading producers and exporters of mint oil and menthol today. Exact acreage and prices fluctuate with weather and market demand.

Fresh pudina leaves are sold in vegetable markets nearly everywhere, often grown on small plots near cities, while hobby gardeners keep a pot of mint on a balcony or windowsill.

How Is Mint Cultivated in India?

Mint is cultivated by planting rooted cuttings or pieces of runner into fertile, moist, well-drained soil, because it propagates vegetatively and not by seed. A loamy soil with plenty of organic matter and a near-neutral reaction suits the crop.

Planting and water

For field mint, suckers or stolon pieces are planted in January to February in rows set about 45 to 60 cm apart. The crop needs frequent irrigation, particularly in the hot months, since mint is a water-demanding plant. For garden pudina, a few stem cuttings placed in water develop roots in a week or two and can then be planted in a pot.

Harvest and distillation

Field mint is typically harvested two or three times a season, with the first cutting a few months after planting, when the plants begin to flower. The cut herb is allowed to wilt briefly in the field and is then steam-distilled in simple stills, producing crude mentha oil. Further processing and chilling separate crystals of menthol from the oil.

Garden culture

Home growers harvest by pinching off shoot tips, which encourages bushy growth. Mint grows best in containers, since runners spread aggressively in open beds. Regular cutting and division every year keep the plant vigorous.

What Is Mint Oil and What Is Menthol?

Mint oil, or mentha oil, is the aromatic essential oil steam-distilled from the leaves and stems of mint, and menthol is the cooling alcohol compound that forms the main part of field mint oil. In Mentha arvensis oil, menthol is usually the dominant constituent, often making up well over half of the oil.

Menthol gives a cooling sensation because it activates TRPM8, a receptor in the skin and mouth that senses cold. The tissue does not actually become colder, which is why menthol feels cool but can also irritate in high concentrations. After crystallisation, the remaining oil is called dementholised oil and is also traded.

• Confectionery and oral care: toothpaste, mouthwash, chewing gum and lozenges.
• Medicinal products: balms, inhalers, cough drops and rubs for aches.
• Flavour industry: beverages, sweets and mouth-freshening products.
• Cosmetics: soaps, lotions and shaving products.

How Is Mint Used in Indian Cooking?

Mint is used in Indian cooking as a fresh flavouring for chutneys, raitas, drinks, rice dishes and snacks, valued for its cool, sweet aroma. Pudina is most often added at the end of cooking or used raw, because heat quickly dulls its fragrance.

• Pudina chutney: a green chutney ground with coriander, green chilli, lemon and salt, served with samosas, kebabs and chaat.
• Pudina raita: curd flavoured with mint and roasted cumin, a cooling side dish.
• Jaljeera and chaas: refreshing summer drinks that rely on mint, cumin and black salt.
• Pudina paratha and pulao: dried or fresh mint leaves are added to dough or rice.
• Biryani and kebabs: mint leaves layer biryani and flavour marinades.
• Pudina tea and sherbet: infused in hot water or sweet cold drinks, and mint also features in mocktails.

Dried mint, sold as pudina powder, is used in chaat masalas and spice blends. Mint leaves can also be dried or frozen in ice trays with water to preserve them for later use.

Does Mint Have Health Benefits?

Mint is a traditional digestive and cooling herb, and modern research has studied its oil for effects on the digestive tract, though mint should not be treated as a cure for any illness. In everyday cooking, the herb is eaten in small amounts and adds flavour rather than significant nutrition.

Fresh mint leaves contain small quantities of vitamin C, carotenoids, iron and manganese, along with plant compounds such as rosmarinic acid. Peppermint oil capsules are used under medical guidance for certain digestive complaints in some countries, and the oil can cause heartburn in some people. Strong mint oil should not be applied near the face of infants and young children, and concentrated essential oils should never be swallowed without qualified advice.

Mint tea is a popular herbal drink and is naturally free of caffeine. In Ayurveda and other traditional systems, pudina is regarded as a digestive and refreshing herb, but such uses are traditional and not clinical claims.

Which Pests and Diseases Affect Mint?

Mint is affected by leaf-feeding caterpillars, aphids, spider mites and fungal diseases such as rust, powdery mildew and root rot. Commercial mentha oil crops are particularly affected by hairy caterpillars and leaf rollers, which reduce leaf area and oil yield.

• Hairy caterpillar and leaf roller: chew leaves and shoot tips in the warm months.
• Aphids and spider mites: suck sap, especially in dry conditions.
• Rust (Puccinia menthae): orange-brown pustules on the underside of leaves.
• Powdery mildew: white coating on leaves in humid or crowded conditions.
• Root rot: caused by waterlogging in pots or heavy soils.

Good drainage, spacing, removal of infected plants and renewal of old patches limit most problems. Because mint is used fresh as well as for oil, farmers and gardeners are advised to follow label directions closely for any plant-protection product.

Why Does Mint Matter to Indian Agriculture and Households?

Mint matters because it is both an everyday household herb and a major industrial crop, giving Indian farmers a cash crop for oil and giving consumers a cheap and flavourful ingredient. For farmers in Uttar Pradesh and nearby states, mentha has become a significant spring and summer crop between the rabi and kharif seasons.

The crop’s challenges include price swings in the international menthol market, high water use in the hot months, and competition from synthetic menthol. Researchers at CIMAP and other institutes work on higher-yielding varieties, better water management and improved distillation. For households, mint is a rare herb that is both easy to grow and widely used, often passed on as a cutting from one neighbour or relative to another.

Bottom Line

Mint, or pudina, is a spreading aromatic herb that serves two roles in India: a cooling kitchen herb in chutneys and drinks, and a large commercial crop for mentha oil and menthol. Growing it is simple in a pot with moist soil and regular cutting.

Frequently Asked Questions

What is mint called in Hindi?

Mint is called pudina in Hindi. The name is used across India for garden mint or spearmint used in cooking. The field crop grown for menthol is often called japani pudina, or Japanese mint.

Is pudina the same as peppermint?

No, pudina is usually spearmint or garden mint, while peppermint is a separate hybrid, Mentha x piperita. Spearmint has a sweeter flavour from the compound carvone, and peppermint has a stronger cooling taste from menthol. Both belong to the genus Mentha.

Where is mint grown commercially in India?

Uttar Pradesh is the main state for commercial mint cultivation in India, especially for mentha oil from Mentha arvensis. Districts such as Barabanki, Bahraich, Rampur and Bareilly are well-known centres. Smaller areas are grown in Punjab, Uttarakhand, Haryana and Bihar.

How do you grow mint at home?

Mint is grown at home by planting a stem cutting or runner in a pot of moist, fertile soil in partial sun. Cuttings placed in water develop roots in one to two weeks. A pot is better than open ground because mint spreads rapidly by runners.

Why does menthol feel cool?

Menthol feels cool because it activates TRPM8, a receptor in the skin and mouth that senses cold. The temperature of the tissue does not actually fall. This is why menthol is used in balms, toothpaste and cough drops.

Can mint be grown all year in India?

Yes, garden mint can be grown for most of the year in much of India if it receives moisture and some shade. It grows fastest in mild, humid weather and slows in extreme heat and cold. Field mint for oil, in contrast, follows a seasonal cycle of planting in winter and cutting in spring and summer.
