Based on the holistic view of the integration of man and nature, combined with the research results, this paper analyzes the inevitability of medical essence, puts forward the view of natural pharmacy, and holds that there must be a natural medical field and its medical system in nature to maintain human life. Its constituent drug elements and related drugs are corresponding unique substances that have specific reactions to life system state information and maintain life, and have specific composition rules and corresponding drug attribute characteristics. Its lumped drug system belongs to the field of natural drugs. The correlation of natural drugs is mainly manifested in the network correlation of drug system, and the network unit is drug-performance-life information. Taking the drug system as the network unit, this paper reveals the composition system, correlation and existence law of single substance drugs, multi-substance drugs and all drugs one by one, so as to connect the drug system in the field of natural medicine with its specific correlation and build a network-related system in the field of natural medicine, so as to find the most suitable drug system, create the best drugs and realize the entry from the drug inevitable kingdom to the drug free kingdom.

Key words: drug system; Online pharmacy; Drug essence; Drug law; Natural pharmacy view

Drugs have the function of treating diseases, and have made important contributions to human health through pharmaceutical research and development. It is true that under the guidance of different pharmaceutical theories, the application forms of drugs are different, and the research and development and production of related drugs have also made great progress.

Under the guidance of the theory of traditional Chinese medicine, the clinical medication of traditional Chinese medicine is mainly single/compound traditional Chinese medicine or preparation, and the medicine comes from clinical practice, which is characterized by adjusting the balance of yin and yang of the medicine as a whole and realizing the holistic view. However, in revealing the essence of pharmaceutical science and guiding the discovery of traditional Chinese medicine drugs with remarkable curative effects, it is urgent to solve the key scientific problems of determining the scientific nature of drug properties (functional indications) and characteristics (drug correlation and synergistic effect).

Western medicine is based on natural drug substances or targeted preparations, and has certain biological activity. It is characterized by the local targeted therapeutic effect of drugs, which embodies the experimental idea of reductionism and clarifies the nature of drugs. However, because the drug system is a single component, its regulated receptors or molecular network nodes have certain limitations, especially for the disease state regulation of complex systems, especially in the adaptability of drug efficacy. Similarly, how to innovate drugs in complex systems to adapt to the treatment of diseases is also a scientific problem to be solved urgently. In order to solve these key problems, the author organically combines nature, scientific thought and pharmacy, and puts forward the viewpoint of natural pharmacy with the analysis and thinking of research work, thus providing guiding ideology for pharmaceutical research, understanding the inevitable kingdom of drugs and entering the free kingdom of drugs.

1 the concept of natural medicine

The basic idea of 1. 1

According to the viewpoint of natural pharmacy, everything in nature exists in balance, and everything is homologous, so there must be a corresponding natural medicine field and its medicine system that can maintain human life, that is, it has a unique medicine composition system, medicine attribute characteristics and its existence law.

As we all know, man is a part of nature, that is, everything in the world. Man and nature (nature) become a harmonious and unified organic whole. What should be the relationship between man and nature? Life support system? The relationship. Man is the existence of life, and so is the natural ecology? Life exists?

What exists, on the one hand, is that natural ecology has its own evolutionary life process; On the other hand, as a member of the objective real world, people's living conditions are inextricably linked with natural ecology, and the disappearance of natural ecology will inevitably lead to the decline of human life. In other words, man and nature are inseparable and closely related. Man is one of the things in nature and exists in nature. Therefore, we must conform to nature in order to obtain the way of natural life science.

Composition and medicinal properties of 1.2

The ingredients of natural medicines and their properties (attributes and characteristics) are the collection of all pharmaceutical systems. Medicine is a substance with a specific function of responding to the state information of life system and maintaining life. Drug combination system is divided into single substance drugs and multi-substance drugs. Monomer drugs include a single drug, called a single entity, a single effective part, called monomer, and a single effective component, called monomer. Multi-substance drugs include multi-flavor drugs, which are called fusion, multi-effective parts and multi-effective components, and are called fusion. Among them, single entity and combined entity belong to solid substance system drugs. Monotypic, synthetic, monomorphic and synthetic drugs belong to the effective substance system.

Monomer drugs are the basic elements of pharmaceutical industry and have a unique composition system. Their pharmaceutical characteristics are the ability to respond to specific life information and the ability to treat corresponding diseases. Its drug substance is separable, and the separated drug responds to its corresponding specific life information, so it has the drug ability to treat corresponding diseases; At the same time, it has combinability, forms related multi-substance drugs, has the correlation of drug interaction, embodies the complementarity or coordination of drug actions, and makes it have drug properties and characteristics more suitable for different and more complicated human disease state systems.

1.3 correlation between natural medicine and medical system 3. 1 correlation of everything in nature According to the holistic view of nature, everything is interdependent, which naturally endows natural medicine with a response to human life information. According to this correlation, it can be predicted that an ideal and perfect world of natural medicine exists.

1.3.2 monomer drug-function-information correlation The natural medicine field endowed by nature should have material medicine elements. Each entity drug element has its corresponding drug function to respond to specific human life information. According to this correlation, we can predict the substance, composition and system of natural drugs.

The natural medicine domain endowed by nature should have effective substances and medicinal components. Every effective substance and drug component has its corresponding drug function to respond to specific human life information. According to this correlation, we can predict the effective substance elements in the field of natural medicine. To construct a pharmaceutical system of effective substances that can be separated and combined with natural solid drugs endowed by the natural medicine community.

1.3.3 Multi-substance drugs-function-information correlation The substance and drug elements in the field of natural drugs endowed by nature all have specific binding element drugs. Each entity medicine element combination medicine has its corresponding medicine function to respond to specific human life information. According to this correlation, we can predict and construct the combined medication system of various natural solid drugs in the field of natural drugs.

Pharmaceutical elements are effective substances in the field of natural medicine endowed by nature, and there are specific drugs with combined elements. Each effective substance and drug element combination system has its corresponding drug function to respond to specific human life information. According to this correlation, we can predict and construct the combined drug system of various effective substances and drug components in the field of natural medicine.

In addition, there is a drug system based on the above correlation and natural drug resources.

1.4 characterization of drug system according to the correlation of natural drugs, the drug system was characterized as a network association system. Mainly divided into: ① The composition system of single medicine and the correlation between its function and life information form an independent network system, which is a single (yuan) network. ② The composition system of multi-substance drugs and the correlation between their functions and life information is a network system composed of multiple single (meta) networks, which is a sub-network. ③ The composition system of all drugs and the correlation between their functions and vital information is a network system composed of all drug networks, which is a general network system.

Each network system responds to its own specific life information, and has the corresponding drug ability to treat human diseases, and the best drug system with the optimal drug ability for the corresponding disease state. The whole network system has the ability to treat all human diseases. Its core is the drug correlation represented by network system and its related effects.
