Mentha spicata
Pronounced Spearmint (SPEER-mint); Mentha spicata (MEN-thuh spih-KAH-tuh); older synonym Mentha viridis (MEN-thuh VIR-ih-dis).
Cool and dry, gently dispersing: a mild aromatic carminative and relaxant that moves stuck gas, unwinds gut and bronchial spasm, and settles hot, rising nausea.
On temperature, Culpeper (1653) reads it as warm. The app keeps cool, the modern reading of what the herb does in the body; the old readings are shown here but do not change it.
Culinary amounts of spearmint (as food and occasional tea) are generally regarded as safe. Medicinal high-dose tea and the essential oil are not established as safe in pregnancy and are best avoided: spearmint has a demonstrated anti-androgen, hormone-modulating effect, and animal studies of concentrated spearmint tea report uterine oxidative stress, so therapeutic doses lack a demonstrated safety margin. Precautionary standard: food and light tea acceptable; avoid concentrated medicinal doses and internal essential oil. Basis: NCCIH-style insufficient-data precaution plus the documented endocrine activity (Grant 2010, Phytotherapy Research). Confirm the AHPA Botanical Safety Handbook class before consumer publication.
Culinary and light tea amounts are generally considered compatible with breastfeeding. As with other mints, large or concentrated medicinal amounts carry a traditional reputation for reducing milk supply and are best avoided by nursing mothers who wish to maintain supply. Modern controlled lactation data are limited. Basis: traditional anti-galactagogue caution for Mentha species plus an absence of controlled lactation studies (Mills & Bone; NCCIH-style insufficient-data note).
Dilute spearmint tea and culinary use are generally well tolerated in children, and, being low in menthol, spearmint lacks the menthol-related airway-spasm risk that makes peppermint and menthol preparations cautioned in infants. Avoid the concentrated essential oil in and around young children, and keep doses small. Basis: NCCIH and pediatric herbal guidance distinguishing low-menthol spearmint from menthol-rich peppermint, plus a long culinary history of safe use.
Spearmint is a gentle, food-grade aromatic and is well tolerated in culinary amounts. Concentrated or prolonged medicinal use of the tea has a documented androgen-lowering effect (it lowered free and total testosterone in clinical trials), so sustained high intake is not a casual matter in men concerned about testosterone or fertility, or in anyone with hormone-sensitive concerns. Like other mints it can relax the lower esophageal sphincter and may aggravate reflux or hiatal-hernia symptoms in susceptible people, though it is milder and lower in menthol than peppermint. The essential oil is concentrated (carvone-rich) and is for dilute topical or aromatic use, not casual internal dosing. Its drying, dispersing quality can feel depleting in very dry, cold, weak constitutions.
No absolute contraindications for culinary use. Use medicinal high-dose tea cautiously in pregnancy, in men with low testosterone or subfertility, and in symptomatic gastroesophageal reflux or hiatal hernia. Avoid the undiluted essential oil internally, and keep concentrated preparations away from the faces of infants and very young children.
Not at conservation risk. Spearmint is a vigorous, easily cultivated perennial that spreads readily by runners and is very widely grown; it is not a United Plant Savers at-risk species. Home-grown or cultivated leaf is preferred and abundant, and its aggressive spreading habit means it is best contained in the garden.
Mint is named among the herbs the Pharisees tithed in Matthew 23:23 and Luke 11:42 (Greek hedyosmon, literally sweet-smelling). Scholars most often identify the wild mint of first-century Palestine as horsemint, Mentha longifolia, with cultivated garden mint of the same genus, including Mentha spicata, as its domestic counterpart; the passage names the genus rather than one modern species. Mint was also valued across the ancient Mediterranean world (Dioscorides, Pliny) as a stomach-settling aromatic.
