Botanical Description

Perennial herb, 30-90 cm tall, a sterile natural hybrid (Mentha aquatica x M. spicata) that spreads by rhizomes and surface stolons rather than viable seed. Stems are square, often purple-tinged. Leaves are opposite, lance-shaped to ovate with a sharply toothed margin, and release a strong menthol scent when crushed. Small, pale purple flowers are borne in dense, interrupted terminal spikes.[2]

Height: 30-90 cm
Habit: Rhizomatous, mat-forming perennial herb, sterile hybrid
Leaves: Opposite, lance-shaped to ovate, sharply toothed, strongly menthol-scented
Flowers: Small, pale purple, in dense interrupted terminal spikes
Stem: Square, often purple-tinged
Root: Spreading rhizomes and surface stolons
Fruit: Rarely sets seed (sterile hybrid); propagated vegetatively
Flowering Period: July-September

Habitat & Distribution

A cultivated hybrid grown worldwide as a crop and garden herb, propagated vegetatively since it rarely sets viable seed; naturalised in damp ground - streambanks, ditches and waste places - in temperate regions.[2]

Harvesting

Aerial parts are cut at or just before full flowering (mid- to late summer), when the essential-oil (menthol) content peaks, then dried quickly out of direct sun, or distilled fresh for essential oil.[3]

Parts: Leaf, Flowering tops
Season: Mid- to late summer, at or just before flowering

Key Constituents

Essential oil (menthol, menthone)[3]

Menthol is the dominant constituent of the leaf oil, responsible for the cooling sensation and much of the antispasmodic and analgesic activity.

Essential (volatile) oilMentholTerpenes / terpenoids
Rosmarinic acid and flavonoids (eriocitrin, luteolin)[9]

Phenolic antioxidants of the leaf.

Traditional Use & History

Peppermint has one of the best-documented traditional uses of any herb - as a carminative and antispasmodic for indigestion, bloating and colic. Enteric-coated peppermint oil capsules are among the most clinically validated herbal treatments for irritable bowel syndrome, and topical or inhaled peppermint oil is traditionally and clinically used for tension-type headache and muscular aches.[1, 2, 4, 5]

Preparations

Infusion (tea)[1]

Dried leaf steeped in hot water, the classic digestive tea.

Enteric-coated oil capsules[4, 34, 35, 36]

Standardised peppermint oil in enteric-coated capsules, the clinically studied form for irritable bowel syndrome, releasing the oil in the intestine rather than the stomach.

Essential oil (topical)[5]

Diluted essential oil applied to the temples and neck for tension-type headache.

Dosage

Enteric-coated oil capsules[34, 35, 36]

Duke (2002) and Commission E guidance: about 0.6 mL enteric-coated oil two to three times daily between meals for IBS-type digestive complaints. Educational reference only, not a prescription.

Dried leaf infusion[34, 35, 36]

Traditional guidance: about 1.5-3 g dried leaf as a tea, up to three times daily for digestive complaints. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[34, 35, 36]Caution

Generally very safe. Essential oil should not be applied to the face or chest of infants or children - menthol can cause respiratory depression. Avoid enteric-coated capsules if taking antacids or acid-suppressing drugs. May worsen GERD by relaxing the lower oesophageal sphincter. Avoid in bile duct obstruction and gallstones.

Safety note[34, 35, 36, 37]Caution

Duke (2002) rates peppermint as +++ with clinical evidence (score 2) for antispasmodic activity, consistent with Commission E approval for IBS (irritable bowel syndrome) using enteric-coated peppermint oil capsules. Enteric-coated peppermint oil is one of the most clinically validated herbal treatments for IBS, reducing abdominal pain and spasm. Dose: 0.6 ml enteric-coated oil two to three times daily between meals (for IBS); 1.5–3 g dried leaf as tea three times daily for digestive complaints. Peppermint should not be applied near the face or nostrils of infants and small children (risk of laryngospasm from menthol). Contraindicated in cholelithiasis (gallstones) (Duke, 2002).
