Hot springs have a sedative effect on the human body. They play an important role in the treatment of neurasthenia, insomnia and other diseases. In addition, hot springs are a magic weapon for beauty and health. Spring is the time of the recovery of all things, at this time the body in the winter package also appears to those bloated, in order to change beautiful clothes in the spring, you need to give the body a full-time beauty body sculpting. But how can it be simple, without leaving traces of body fat, but also make the skin beautiful and smooth it? At this time is undoubtedly the best choice for hot springs at this time.
The beauty regimen indicates that the spring weather is dry and windy. It is very easy for the skin to look dry. At this time, we may choose to take a hot spring bath. Spring hot spring baths are the best seasons for the four seasons. Does not eliminate fatigue, or nourish the skin. In addition, hot springs often contain some special chemicals that can often change the skin's pH to achieve skin care benefits.
It is understood that hot spring water can generally be divided into carbonated springs, salt springs, sulfuric acid springs, sulfur springs, and radioactive springs. These substances can precipitate on the skin when soaked, and can penetrate into the body after being absorbed by the skin, thereby promoting Blood circulation and change the skin's pH and other effects. Among them, salt spring can change the skin permeability, inhibit skin cell division, affect skin metabolism, thereby preventing skin aging; sulfur mineral springs can affect the skin's immune system, soften skin keratin, and even treat chronic skin diseases.
In addition to the most common soaking method, modern hot springs also have a variety of hot springs, not only beneficial to women's skin care, but also to several types of massage-style hot springs. Among them, the most popular among women is the hot spring waterfall bath. This hot spring method was originally combined with a natural hot spring and a waterfall. It uses the fall of a hot spring waterfall to bathe the body to promote blood circulation, and it has the effect of beauty and body sculpting.
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.
