Why are some capsules transparent and some are colored? Why are the two ends of the capsule often different in color?
Some people believe that each medicine has its own color, or the color represents its safety.
Well, you think too much. The color of capsules actually plays a role in the production process.
Bright capsule color can reduce people's rejection of drugs. After all, the powder in the capsule always makes people feel bitter.
Secondly, the pharmaceutical factory does not only produce one drug, and different colors are easy to distinguish. As for the transparent capsules, it is for people to notice the state of the powder or particles and reduce the danger.
What are the ingredients of the capsule? Its feel and smell give people a sense that it is plastic. But you certainly did not expect that the invention of capsules was far before plastic. In 1500 BC, Egypt had the first capsule in the world. But this capsule only leaves space in the closed pill. It was not until 1846 that the two section hard capsule we see now was invented.
In 1986, people panicked about the capsule because of the outbreak of mad cow disease.

Because the composition of the capsule is gelatin, which is the product of partial hydrolysis of collagen and is made from cow skin, cow bone or pig skin. After the outbreak of mad cow disease, some businesses chose to change the raw materials, using fish skin, fish scales and chicken skin. Some people changed their thinking and invented the plant capsule.
This has brought good news to some religious people, because they refused to eat pigs and cows, but also refused gelatin capsules. The birth of plant capsule makes it convenient for them to use medicine.
However, it should be noted that the role of the capsule is not just to look beautiful, or to make the medicine no longer bitter. Someone will take the capsule apart and take the powder. This will not only affect the efficacy, but may also be harmful. Because the powder may stimulate the throat and esophagus to a certain extent, it is easy to cause cough and other reactions. Some capsules need to be dissolved in the intestine. If swallowed directly, the powder may be destroyed by gastric juice.
