Mint leaves can be steeped in boiling water for 10 minutes.

You can also decoct mint leaves with water for 10 minutes and mix with sugar to drink. Mentha piperita is a traditional Chinese medicine with the effects of clearing the head and eyes (clearing wind-heat from the head and eyes), dispersing wind-heat, clearing the pharynx and rashes (helping the rashes to disperse), and dispersing the liver and promoting the flow of qi. It is aromatic and pungent, and is prone to sweating and exhaustion of qi, and should not be used by those who suffer from weakness and excessive sweating. The therapeutic effect of mint leaves is limited, and the use of a single flavor of the drug to treat the disease is not effective, so you can not rely only on mint leaves in water to drink to treat the disease. If the body exists uncomfortable symptoms, should be timely consultation, so as not to delay the treatment.
