Compared with tablets, capsules have various advantages. For example, capsules have strong sealing properties and are not easy to oxidize, and powders do not need to be added with adhesives. Adhesives are also a safety hazard; more importantly, capsules can control the decomposition time of the drug.

　　For those drugs that decompose in the stomach and destroy the effect of taking, only the slow-release effect of the capsule coat allows the capsule to dissolve in the small intestine , In order to achieve better results. The tablet does not seem to have a shell and has relatively few additional ingredients.

　　In fact, a complete tablet at least contains several coatings such as an isolation layer, a powder coating layer, a sugar coating layer, and a colored sugar coating layer.

　　The coating materials include syrup (colored syrup). ), glue, talcum powder, white wax, etc. The source of glue is also animal gelatin. Sometimes we can even taste the taste of gelatin.

　　The animal protein contained in the animal gelatin capsule is prone to bacteria and deterioration, so it must be preservative and sterilized during the production process, and sometimes preservatives are added.

　　Safety issues such as excessive heavy metals in industrial gelatin capsules are also emerging worldwide.

　　In the pharmaceutical industry, plant capsules have the following three advantages, which are not available in tablets and animal gelatin capsules:

　　1. Green and environmental protection

　　Many plant gums are extracted by physical extraction methods, extracted from marine and terrestrial plants, will not produce rotten stench, also greatly reduce the amount of water used, and reduce environmental pollution. In the production process of capsules, there is absolutely no environmental pollution. Compared with the waste generated by gelatin capsules, the production process of plant capsules is almost "zero emission".

　　2. Represent the future development trend

　　Large international companies all use plant capsules. The US FDA (Food and Drug Administration) has proposed that plant capsules will be gradually adopted in the future and gelatin capsules will be completely eliminated. Feng Guoping, the former deputy director of the Drug Registration Department of the State Food and Drug Administration, believes: "The way and possibility of artificial pollution of plant capsules is relatively small. Therefore, replacing animal capsules with plant capsules is the fundamental way to solve the chronic diseases of capsule pollution."

　　3. Widely accepted

　　With the increasing awareness of people’s self-care, the development of vegetarianism, and the influence of religions and other factors, gelatin capsules derived from animal bones are also vulnerable to the rejection of dietary habits stipulated by different ethnic groups and religious beliefs. They are purely natural and plant-based. Sexual capsule products will become the leading direction in the development of capsule products. Plant capsule shells are unanimously recognized by different cultures, nationalities and religions.
