1. First pick 4-5 fresh loquat leaves from the loquat tree, rinse the dirt under the faucet at home, and then use a brush to clean the fluff on the back of the loquat leaves to avoid Irritation to throat.

2. Then put the cleaned loquat leaves into a basin, cover with water, soak for 15 minutes, and then rinse them under the faucet.

3. Prepare a piece of rock sugar, cut the leaves into pieces and put them into a cooking pot. Pour in about 700-800 ml of water and cook over high heat. After the leaves are boiled, use a slotted spoon to stir the floating leaves. Once, turn to medium-low heat.

4. At this time, put the prepared rock sugar into the pot and cook for 15-20 minutes. (Be careful not to open the lid immediately after cooking, and continue to simmer for a while.)

5. Finally, pour out the water from the cooked Pipa leaves. The color will be brown, and it will turn wine red after cooling, and the smell will still be there. The leaves have a faint fragrance, and the boiled water can be used as daily tea. It has the effect of relieving cough and reducing phlegm.
