Four botanicals, in two stages. A slice of ginger and a tiny pinch of star anise simmer for three minutes; the heat then goes off and ten mint leaves join half a gram of dried chamomile to steep, covered, for five minutes, warm underneath and cool on top. The Journal's note on brewing methods flags this sequence: the European Medicines Agency's template says aromatic herbs like mint may be infused at the end of a decoction. Its sibling, Warm Mint Comfort Tea, uses the same five ingredients in different proportions: half again as much ginger, a longer five-minute simmer, two fewer mint leaves and more chamomile, built for winding down an evening rather than settling a meal that just happened.
The evidence for what it's meant to do is real but narrow. Ginger's one well-supported use is nausea; even its most mechanistic effect, faster gastric emptying, doesn't survive a symptom diary: in two randomised trials, 1.2 grams sped emptying by half in healthy volunteers and changed no reported symptom. Mint's coolness is a trick, not a temperature: menthol shifts the TRPM8 receptor's activation point into the warm range, so a cold-reporting nerve fires at room temperature. Chamomile fares best of the four: Europe's herbal medicines committee lists chamomile tea, at 1.5 to 4 grams per 150 millilitres, as a traditional remedy for minor gastrointestinal complaints including bloating, a use this recipe's half gram sits comfortably under. Star anise supplies sweetness more than medicine; its flu-fighting reputation belongs to shikimic acid, the Tamiflu precursor, not any antiviral action of its own.
Drink it hot, right after the meal it's meant to follow, and let the mint do the work rather than expecting much from the chamomile at that dose. One caution: buy star anise from someone who can name the species. Illicium anisatum, Japanese star anise, looks nearly identical dried and is toxic, a GABA-A blocker whose active compound has sent infants into seizures from a single cup. The 0.05 grams this recipe asks for, a tiny pinch of the real thing, is already doing its job.
