How to store crushed Chinese medicinal materials

Use glass, ceramic or stainless steel containers with good sealing to store crushed Chinese medicinal materials. Avoid using plastic containers, as some plastics may react with the ingredients in Chinese herbs and affect the quality of the herbs. At the same time, the container should be kept dry, clean, no odor residue.

Controlling the temperature and humidity of the storage environment is one of the key factors. In general, the crushed Chinese medicinal materials should be stored in a cool and dry place, the temperature is appropriate to 10-20 degrees Celsius, and the relative humidity is best controlled below 60%. The high temperature and high humidity environment can easily lead to mold and deterioration of medicinal materials. In the humid season, you can consider using desiccant or dehumidification equipment to reduce the ambient humidity.

The container for storing crushed Chinese medicinal materials should be placed in a place to avoid direct sunlight, or choose a container with good shading performance. In order to prevent contamination and cross infection of medicinal materials, different kinds of crushed Chinese medicinal materials should be stored separately to avoid confusion.

For some crushed Chinese medicinal materials that are easy to produce insects, appropriate pest control measures can be taken. For example, place some items with repellent effects such as Sichuan pepper and garlic, or use pest control agents that meet the standards, but pay attention to the amount and safety of pest control agents to avoid secondary pollution of medicinal materials.
