For digestion, regulating blood lipids, relieving cough and reducing phlegm, the methods are as follows:
1. Wash the oranges first, then cut them into small slices with a knife, just enough to expose the pulp.
2. Then sprinkle a little salt on top of the pulp, and poke the pulp with a toothpick to let the salt penetrate into the pulp.
3. Then cover the piece of orange peel you just cut and secure it with two toothpicks to make it look like an uncut orange.
4. Pack it in a container, and then put the container into the pot. After the water boils, turn to low heat and simmer for about 20 minutes.
