Natural medicine refers to natural pharmaceutical substances and preparations adopted by medical personnel under the guidance of modern medicine. The sources of these medicinal substances include plants, animals and minerals, but in animal and plant sources, transgenic animals and plants are generally not included.
Up to now, the medical systems that form a systematic theory on the use of natural medicines are: China medicine, Indian Buddhism medicine, Islamic medicine, European traditional herbs, South American ethnic medicine and African ethnic medicine. Among them, China medicine is considered as the most deeply developed natural medicine system.
In the research and development of natural drugs, researchers should pay attention to the following points: (1) In the research process, researchers should design and evaluate clinical trial schemes with modern medical theories as the guiding ideology.
(2) In the process of research, researchers must have sufficient evidence to determine the effective components of drugs.
(3) In the research process, there must be sufficient experimental data as evidence of the research conclusion.
(D) In the research process, we should ensure the sustainable utilization of resources.
