Mistakes and taboos
The public simply understands it as a kind of fruit, but it is not an exaggeration to say that Chinese medicine is "all treasure". The skin, core, collaterals and things of oranges can be used as medicine, but the diet is very particular. The following are some of the most common misunderstandings when eating oranges.
Mistake one
When many people eat oranges, they like to tear off the white tendons outside the orange pulp. In fact, this way of eating has not made the best use of it. The white reticular collaterals outside the orange pit are "orange collaterals", which have the functions of dredging collaterals, resolving phlegm, promoting qi circulation and promoting blood circulation. It is not only a good diet therapy for patients with chronic diseases such as chronic bronchitis and coronary heart disease, but also an auxiliary treatment for chest and rib pain caused by chronic cough.
Error 2
Furthermore, after eating oranges, people often soak in water with orange peel and use fresh orange peel as dried tangerine peel to eliminate phlegm. They think that drinking fresh orange peel water often in autumn is of great benefit to health care and disease prevention. Actually, this is a misunderstanding. Pericarpium Citri Tangerinae has the functions of regulating qi, eliminating dampness and resolving phlegm, but it is not fresh orange peel, but is made from mature orange peel by sun drying or air drying.
Fresh orange peel refers to the fresh peel when eating oranges. Fresh orange peel contains more volatile oil and does not have the medicinal effect of dried tangerine peel. Soaking fresh tangerine peel in water can not only give full play to its medicinal value, but also stimulate the stomach because of the strong smell of volatile oil. So, don't soak fresh orange peel in water at will.
