Why people make this tea

Hong Kong summers are hot, but the air-conditioning on transit, in malls and offices runs very cold — so many people end up with a stuffy or runny nose and cough. In traditional thinking “the nose is the window of the lungs,” and when lung-qi can’t spread, you get sneezing and a clear runny nose — signs of lung-cold. This simple tea is traditionally used to warm the lungs and ease that clear, watery runny nose.

What studies say about the key ingredients

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

    Overall, acute and delayed nausea and vomiting did not differ significantly between ginger and control groups. A subgroup taking 1 g/day or less for over four days had less acute vomiting (OR 0.30).Limitation: Clinical heterogeneity between trials required subgroup analyses, and the authors state that sufficiently large, high-quality RCTs are still needed.PubMed 36501010 · 3 more ginger studies
