How to Prevent the Mold Growth of Chinese Herbal Medicines?

Maintaining an appropriate temperature is necessary to prevent mold in Chinese herbal medicines. The temperature should not be too high, and better storage can be achieved under low temperature conditions. At the same time, an appropriate humidity level must be maintained. If Chinese herbal medicines become damp, it can easily lead to mold. Another method is to store Chinese herbal medicines in a sealed container to prevent mold.

1. Chinese herbal medicines are prone to mold and deterioration during storage. Attention should be paid to the storage method. Firstly, moisture-proof, heat-proof, and ventilation methods can be used to keep the herbs dry. Moldy herbs can be brushed and dried after being washed with running water, vinegar, alcohol, etc. To prevent insects from damaging the herbs, proper containers can be used, sealed with wax, or stored in refrigerators at around 5 degrees Celsius. To prevent discoloration and oiliness of the herbs, they should be kept dry, away from light, and refrigerated.

2. The storage location should be selected to be high, dry, well-ventilated, and avoid direct sunlight. The ground is preferably cushioned with cedar wood. Natural moisture absorbers such as quicklime can be placed in less tightly sealed warehouses and pharmacies to absorb moisture. Various drying equipment for medications, such as ovens, should also be available in the storage area. Different containers should be selected for storing different types of medications. The most important and effective method to prevent mold is the drying method, such as sun-drying.

3. Once Chinese herbal medicines have molded, they should not be boiled for consumption, as the components and efficacy of the herbs have changed. Consuming such boiled herbs will undoubtedly affect one's health and may even cause poisoning. Therefore, it is best not to consume them.
