Now described as follows:

1. Medicinal materials containing more starch, such as Alisma orientale, Rhizoma Dioscoreae, Radix Puerariae, Radix Astragali, etc. , should be cut into pieces, dried in time, and stored in a ventilated, dry and cool place to prevent insects from eating and getting wet.

2. For medicinal materials containing a large amount of volatile oil, such as mint, angelica, costustoot, Ligusticum wallichii, etc. After slicing, the drying temperature is lower than 30℃; When the temperature is higher than 30℃, the effective components will be lost, and the ambient temperature should not be too high during storage, otherwise the fragrance will be lost or the oil will overflow, which is easy to absorb moisture, mildew and moth. It should be stored in a cool and dry place.

3. For pieces containing more sugar and mucus, such as Cistanche deserticola, Radix Rehmanniae Preparata, Radix Asparagi, Radix Codonopsis, etc. It is not easy to dry after processing, and it is easy to become soft and sticky in high temperature and high humidity environment, and it is easy to be polluted. Should be mildew-proof and moth-proof, stored in a ventilated and dry place.

4. Seed medicinal materials, such as perilla seed, arborvitae seed, radish seed, coix seed, etc. , should be stored in closed storage tanks and cans to prevent pests and rats from biting.

7. Honey-baked products, such as coltsfoot flower, licorice, loquat leaves, etc., are not easy to dry because of their high sugar content, and are particularly prone to softening due to moisture or adhesion, and are easily polluted.
