After the age of 30, people's joint fibers degenerate, their elasticity weakens, their ability to stretch articular cartilage gradually weakens, and their ability to recover to the original state weakens. Coupled with the reduction of joint fluid, articular cartilage becomes dry. Therefore, when people reach a certain age, articular cartilage is easily damaged and worn, leading to degenerative arthritis and other diseases. For various joint diseases caused by cartilage wear, injury and deformation, traditional medicine usually uses drugs to relieve pain (such as glucosamine, hyaluronic acid, analgesic ointment, etc.). ), in addition to hot compress, massage and electrotherapy. But the problem is that these therapies cannot regenerate human cartilage. For advanced patients, joint surgery can also be used in medicine. But joint surgery, besides being expensive, can't completely eliminate the pain. Moreover, artificial joints are "external things" after all, and their activities are limited. After impact, they are prone to dislocations, accidental injuries and other accidents, and they will be operated again in a few years. In view of this situation, many developed countries in the world are gradually looking for new methods to regenerate human cartilage. Since 1980s, with Europe, America and Japan as the center, pure natural shark cartilage powder, especially pure natural black herring, has been used to realize the clinical verification of articular cartilage regeneration, forming a trend of alternative therapy in the world. Of course, this therapy also has disadvantages. First of all, not all sharks are effective, and it is also doomed to the difficulty of selecting materials. Secondly, the active ingredient of pure natural silver carp is protein, which is easy to lose its curative effect due to thermal denaturation during processing, so the technology is exquisite. All this makes it a little more expensive. However, despite this, we still expect that the popularization of cartilage regeneration therapy will not be too far away. I hope it helps you, and I wish you a speedy recovery!
