1, pay attention to keep warm The weather in winter is cold. At this time, many people wear thick clothes to keep warm. But do you know that the head, hands, and feet at this time need to focus on keeping warm and must not be ignored. Experts tell us that there is a very important role between the warmth of the head and the thermal balance of the body. Therefore, in order to be healthy, special attention should be paid to some exposed parts in winter, such as wearing a hat and gloves. 2, maintenance Winter maintenance is a very important task. The colder the weather is, the more you need to protect your hands and feet and develop good habits for picking your hands. The pickpocket can not only promote the blood circulation of the hand, reduce the possibility of frostbite, but also prevent colds. It also has a good health care function for our brains. In addition to the habit of picking up hands, winter is best and can be used every day to soak your feet. This not only reduces cold, but also has the effect of eliminating fatigue and promoting sleep. It is a very healthy and scientific way of life. 3, eat less cold, cold food If you eat cold or cold food in winter, it is easy to cause various gastrointestinal diseases. Therefore, for good health, we must pay special attention to the warmth of the body and stomach during the winter, and eat less cold food, especially those who are physically weak and have poor health. In addition, if you want to achieve the effect of warm stomach, you can add some pepper or ginger in the daily diet, which can play the role of warm stomach and health care. 4, keep a good mood every day Did you know that a good mood not only opens the mind, but also has a huge impact on physical health, and it also has the effect of nourishing the stomach. Many people in modern times have gastrointestinal problems. This is mainly due to the pressure of work life, and the quality of sleep is also not good, so that it is often kept in a tight state for a long time, which will affect the normal operation of the stomach. Therefore, if you want to better regulate the stomach in the winter, you must maintain a good mood, so that the gastrointestinal tract can run more smoothly. 5, exercise Many people stopped exercising because of the cold weather. Actually, this is not scientific. When the winter temperature is low, it is better for the elderly and children to reduce the number of times outdoors, but the exercise can not stop, but should carry out some simple exercises indoors, such as jogging, etc. This will not only increase the pressure on the heart and lungs, but also Can also exercise. In addition, the exercise time is also stressful, it is best to exercise in the afternoon from 3 to 4 o'clock. An active substance is the main active ingredient in a drug. Take a simple aspirin for example. Acetyl salicylic acid is synthesized through chemical process and purified to a specified purity. The synthesis of acetyl salicylic acid is made by adding various excipients, such as fillers, adhesives, disintegrating agents, etc., and then pressing it into tablets. The production of apis is generally either pure chemical synthesis, biological fermentation, or semi-synthesis, with biological fermentation followed by extraction followed by synthesis. Not all pharmaceutical enterprises make API by themselves, and many manufacturers do not have the scale to produce API. Even if there is large-scale production, the cost of production may be much higher than that of procurement. Therefore, most manufacturers buy bulk drugs, and then make preparations, so that the production of drugs can be completed without a very large scale. At present, China and India have become the two largest API producers in the world. Many European and American pharmaceutical companies, even some of their own original drugs, will give up the production of API as the patent expires and the market matures, and turn to purchase apis from China and India,API production generally go through laboratory, generated through laboratory bottle container canister, taking after successful, pilot magnification, which is to enlarge the quantity of the production, then no problem tends to be faced with a lot of small scale experiment, a very simple example, the heating process, due to the relatively small amount in the laboratory, uneven heating cases is less, But if it is scaled up to a few tons of pot, at this time the heating may be not hot in this place, where the paste pot, at this time you need to stir, but the speed of mixing is appropriate, this process needs to calculate or grope. Finally from the pilot test, and then to the formal production, the volume of further amplification, and will face a lot of new problems. Therefore, although some drugs are generic, the research and development of the whole process from small test, pilot test to the final mass production is indispensable, so even generic drugs have very high research and development costs. api meaning,api products to buy,best api products,cheap api products,best buy products api,best api products Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropic.com
