ABSTRACT: By consulting the literature about drying methods of root and rhizome medicines in recent ten years, the drying methods of root and rhizome medicines were summarized in order to provide reference for further research and development of drying methods of root and rhizome medicines.
It is believed that the traditional drying methods are still the main drying methods for roots and rhizomes. The modern drying methods such as microwave drying equipment, infrared drying and far infrared drying are still in the stage of laboratory research. Whether the modern new drying methods can be used in large-scale drying still needs to be further explored.
Key words: root and rhizome medicinal materials; drying method; microwave drying of medicinal materials
Traditional Chinese medicine is the quintessence of our country. Its advantages, such as small side effects, strong drug resistance, low price and long-term use, have been paid close attention to by the whole society and strongly supported by the government. Although China is a big producer of Chinese herbal medicines and has abundant natural medicinal resources, there are few Chinese herbal medicines that can enter the international market. Therefore, expanding the production scale of Chinese herbal medicines, improving production technology and ensuring the quality requirements of Chinese herbal medicines are the only shortcuts to speed up the modernization of Chinese herbal medicines.
