1, no pesticide residue: Chinese herbal medicines are often threatened by some pests and diseases in the process of planting and harvesting, so people often spray them with pesticides in order to ensure the stability and quality of Chinese herbal medicines. However, pesticides can cause potential harm to human body. Therefore, Chinese herbal medicine suppliers need to strictly control and manage the use of pesticides to avoid pesticide residues. Before Chinese herbal medicines enter the market, they need to undergo strict testing to ensure that there is no pesticide residue.
2. No heavy metal pollution: Some Chinese herbal medicines usually grow on land containing heavy metals, which will lead to the risk of Chinese herbal medicines being polluted by heavy metals. Heavy metals will accumulate in Chinese herbal medicines and are difficult to remove. Therefore, heavy metal pollution often has a great impact on the quality of Chinese herbal medicines. Some metal decorations used in the air, such as nickel plating and chromium plating, will release a large number of metal ions, thus contributing to the metal concentration in the air.
3. Complete effective components: The effective components of Chinese herbal medicine refer to substances or chemical components with pharmacological activity, which are the main sources of Chinese herbal medicine efficacy. Chinese herbal medicines need to contain effective components within the normal range, and the quality must be stable to ensure their curative effect. In the production process of Chinese medicinal materials, strict inspection is needed to ensure the stability of effective components.
4. No chemical additives: In traditional Chinese herbal medicines, some chemicals are often added to ensure their quality and stability. However, these chemicals will cause harm to human body, so the current Chinese herbal medicine suppliers usually do not add chemicals to maintain the purity of Chinese herbal medicines.
