Mint Tea: Peppermint, Spearmint and What the Cup

Mint tea, in summary: Mint tea is caffeine-free with modest evidence for digestive comfort; peppermint stronger but can worsen reflux, spearmint gentler.

Last reviewed by the teas.co.uk team in May 2026.

Mint tea is the cooling, refreshing, digestive supporting herbal infusion, peppermint and spearmint are the dominant species, but mint family includes dozens of edible varieties. The cup is genuinely useful for after meal digestion, the evidence is real, and mint pairs beautifully with green tea (Moroccan style) or as a stand alone caffeine free drink.

The mint family

"Mint" refers to plants in the genus Mentha. Major species used in tea:

Peppermint (Mentha piperita). The dominant medicinal mint. High menthol content, strong cooling sensation.
Spearmint (Mentha spicata). Sweeter, gentler. Lower menthol. The mint in chewing gum.
Field mint / Wild mint (Mentha arvensis). Slightly grassier, more aromatic. Used in some Three Mint blends.
Apple mint, chocolate mint, pineapple mint. Specialty cultivars; less common in tea.

The actual evidence

Digestive support (strong evidence)

Peppermint oil has solid clinical evidence for IBS symptom reduction. The menthol relaxes intestinal smooth muscle. Tea strength peppermint after a heavy meal genuinely helps for many drinkers.

Headache relief (modest)

Topical peppermint oil has some evidence for tension headache relief. Tea strength is gentler, drinking helps via hydration and the comforting ritual rather than direct pharmacology.

Bad breath (real)

Mint's aromatic compounds mask bad breath short term. Modest direct antibacterial effect.

Antispasmodic (modest)

Peppermint relaxes smooth muscle, which some drinkers find eases mild gut spasms and period cramps.

Decongestant (modest)

Inhaling steam from hot mint tea provides some decongestant effect. The menthol opens nasal passages temporarily.

The reflux concern

Peppermint relaxes the lower oesophageal sphincter, which is helpful for some digestive issues but can WORSEN gastroesophageal reflux disease (GERD). If you have reflux, peppermint may not be your friend. Spearmint has less of this effect.

What mint tea tastes like

How to brew mint tea

1 tea bag (or 1 tsp dried mint) per 200ml.
Just boiled water.
Cover the cup. Steep 5-7 minutes.
Drink black, with a slice of lemon, or with a teaspoon of honey.

Covering the cup matters, volatile menthol and aromatic compounds escape as steam.

Foraging fresh mint

Mint grows easily in UK gardens (often invasively). Picking fresh leaves, washing, brewing immediately produces a noticeably more aromatic cup than dried mint. 6-8 fresh leaves per 200ml; 5-7 minutes covered.
