Key Constituents
Menthol is the dominant constituent of the leaf oil, responsible for the cooling sensation and much of the antispasmodic and analgesic activity.
Phenolic antioxidants of the leaf.
Pharmacological Actions
Appetite stimulant for loss of appetite (approved use under German Commission E)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)

Safety, Cautions & Contraindications
As a member of the daisy family (Asteraceae/ragweed), it can cause allergic reactions in sensitive people; high doses reportedly cause stomach cramps, nausea and vomiting.
Avoid during pregnancy because of a traditional uterine-stimulating reputation.
Although traditionally used to support milk supply, there is no scientifically valid clinical evidence for the galactagogue use.
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.
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).

Botanical Description
Branching annual herb with a hairy, reddish, ridged stem and spiny, deeply lobed leaves with prominent pale veins. The flower heads are pale yellow, thistle-like, surrounded by a whorl of spiny, leaf-like bracts, giving the plant its 'spotted thistle' appearance.[4]
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]
Habitat
Grows on dry, sunny waste ground, roadsides and rocky slopes; native to the Mediterranean region and Western Asia and naturalised elsewhere as a garden escape.[4]
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
The flowering aerial parts are cut as the plant comes into flower, in summer, and dried in a warm, shaded, airy place to preserve the bitter principle cnicin.[4]
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]
Traditional Uses
Blessed thistle has a long European folk reputation as a bitter digestive tonic for loss of appetite and dyspepsia (an approved use under German Commission E) and, more anecdotally, as a traditional galactagogue to support breast-milk supply, though robust clinical evidence for the latter is lacking.[4, 11]
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
Dried flowering herb infused briefly in hot water as a bitter digestive tea, taken before meals.
Dried leaf steeped in hot water, the classic digestive tea.
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.
Diluted essential oil applied to the temples and neck for tension-type headache.
Dosage
Traditional herbal references suggest around 1-2 g of dried herb per cup, taken before meals, up to three times daily. Educational reference only, not a prescription.
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.
