In general, it is customary to steam oranges to make some cough remedies to treat cough. Usually, simply steaming oranges is not a good treatment for cough. You can peel the top of the orange, hollow out a hole in the middle, put some zebrawood into the orange, add some rock sugar, and then put the orange on the steamer for 30-40 minutes. After the oranges are soft, the sugar will melt into the orange, and the mother-of-pearl will also be inside the orange.
