Problems solved by technology

Since the reaction reagents are basically chemical agents, their medication safety risks are great
At the same time, in view of the complexity of the components in the extract of traditional Chinese medicine, the possibility of adverse reactions between the treatment reagents and the components of the extract cannot be ruled out under the circumstances that the existing cognitive ability and technical means cannot be fully grasped, thus further increasing the Potential drug safety hazards of Chinese herbal medicine extracts and extracts obtained by this treatment method
In the material adsorption type treatment method, the adsorption material uses chemical and physical methods to adsorb heavy metal ions. Although it avoids the problem of reagent retention in the reagent reaction type treatment technical scheme, it cannot be ruled out due to the limitations of existing cognitive ability and technical means. Its adsorption of active ingredients in Chinese herbal extracts or extracts, resulting in a reduction in efficacy

Abstract

The invention provides a treatment method used for reducing a heavy metal content and a pesticide residue content of a traditional Chinese medicine material. Through the sequential steps of dry picking and purification, washing with drinking water, moistening by means of an edible basic solvent, washing with warm water and the like, impurities of silt and the like, which are rich in heavy metal and pesticide residue components, on surfaces of the traditional Chinese medicine material are completely removed, and by means of a metabolic function of the traditional Chinese medicine material, discharge of harmful components, of heavy metal, pesticide residues and the like, in the traditional Chinese medicine material is promoted so that with few steps, low intervention and high edible safety,both the heavy metal content and the pesticide residue content of a final product produced by subjecting the traditional Chinese medicine material to treatment can meet the requirements of notes on plant medicines in United States Pharmacopoeia.

Description

technical field [0001] The invention relates to the technical field of production of Chinese medicinal materials, in particular to a treatment method for reducing the content of heavy metals and pesticide residues in Chinese medicinal materials. Background technique [0002] In the revised opinion draft of the 2020 version of "0212 General Rules for the Testing of Medicinal Materials and Decoction Pieces", the State Pharmacopoeia Commission plans to conduct a comprehensive inspection of the limits of heavy metals and harmful elements (lead, cadmium, arsenic, mercury, copper) on plant-based Chinese medicinal materials. And 33 pesticides were included in the banned list. Since traditional Chinese medicinal materials are agricultural and sideline products first, their planting management is not significantly different from other agricultural products produced by planting methods. Therefore, growers must implement pest and disease protection measures to ensure production. Due t...
