If you can, try to drink some water boiled with jujube often. For example, ten jujubes (you can choose Xinjiang Jujube, the quality is better, it is said that boiling water is easy to get angry without removing the core), put them in a health pot (or other containers, it is best not to use metal utensils, because jujubes have the same origin of medicine and food, so we use them as Chinese medicine here, and metal things can't be used to stir-fry Chinese medicine), soak them for a while, and then you can drink them after boiling water, no matter.
