Ginger is warm and spicy, and it is called the tribute of Guangdong's three treasures (tangerine peel, Lao Jiang and straw grass). It can be said that ginger is widely used by the people. Besides serving as a side dish and main course, dietotherapy is also very common. In use, choose according to different needs. For example, when cooking, use tender ginger (also known as ginger, purple ginger and ginger bud). Tender ginger is crisp and less spicy. Used for frying beef and chicken slices. It has the functions of invigorating the spleen, expelling wind, removing dampness and waking the stomach, which is generally acceptable to people who don't like spicy food. But from the point of view of dietotherapy value, tender ginger is far from old ginger. The so-called "ginger is still old and spicy" does make sense. Motion sickness and seasickness, taking ginger or ginger juice is very effective. Its advantage is to stop dizziness and vomiting without drowsiness. It is said that many airlines have prepared ginger candy for passengers in need on the plane. In fact, long-term travelers might as well prepare some ginger candy for a rainy day. Many friends who like climbing, swimming or diving have the experience of carrying ginger. Because the swimming time is too long, Korean cars can regain their strength by chewing ginger when they are exhausted. Walking on the mountain in the cold wind and rain, or when the smog is too heavy, chewing a piece of ginger can prevent the body from being attacked by external evils and suddenly fainting. It can be seen that ginger is a life-saving food. Ginger blooms every summer and smells delicious. Meanwhile, you can buy ginger flowers in the market and grow them at home. They begin to sprout in September, and you can see the tender ginger in fifteen days. One and a half months after the tender ginger was unearthed, you can see the old ginger in the market. This is the season after beginning of winter, which is suitable for keeping warm and nourishing.
