Shiuli tree.

Wake up early in the morning and wash two or three leaves of Shiuli tree well with water. Chew well and consume as much juice as possible. Consume the juice and discard the rest. If your cough produces phlegm, there are not many better medicines in the market. Although its juice is very bitter in nature, but if you eat it regularly, the intensity of cough will decrease and the traces of phlegm will also disappear.
