1, soaking plantain in water is also good for your health. Plantain is sweet, cold and slippery, and is good at clearing heat, diuresis and detumescence, so it is often used for damp-heat colic, diarrhea and jaundice.

2. Oral plantain decoction can increase tracheal secretion, which has obvious expectorant effect, and its action intensity is not as strong as that of Platycodon grandiflorum.

3, plantain is cold, which can not only clear away heat and cool blood, but also detoxify and reduce swelling, so it is often used for sore throat, blood-heat bleeding, carbuncle swelling and pain.
