"According to the new technology, the' secondary development' of Radix Isatidis is nearing completion, and the oral dosage is reduced by 80%. Animal experiments have proved that the effect is five or six times stronger. " Zhong Nanshan said that new drugs still have to undergo clinical trials and approval, and the time to market is still uncertain.
Banlangen granule is a widely used traditional Chinese medicine granule for clearing away heat and toxic materials. Zhong Nanshan introduced the second development project of Radix Isatidis, which was jointly carried out by Guangzhou Medical University and two state key laboratories in Macau. He said that the project has been going on for nearly 10 years, and it has been clear that there are four main components of Radix Isatidis, namely sterols, lignans, indoles and polysaccharides. Their functions are different, some of them have a slight effect of killing viruses, but more of them are to prevent viruses from entering cells or inhibit the development of inflammation.
Zhong Nanshan believes that the purification and "secondary development" of Radix Isatidis is one of the important ways to modernize Chinese medicine. All sciences are developing, but at present, the vast majority of Chinese medicine is empirical medicine. To realize the modernization of traditional Chinese medicine, we must first develop in the direction of evidence-based medicine, and this road must be taken.
