During the storage of Chinese herbal medicines, it is mainly necessary to avoid the variation of insects, molds, discoloration, odor loss, decay, weathering, melting and adhesion.
The main factors causing drug deterioration are:
Temperature: Medicinal materials have a certain range of temperature in terms of adaptation. If the temperature is too high or too low, the quality of the medicine will change. When the temperature is above 35 degrees, fat-containing drugs will be separated due to heat, so that less oil; drugs containing more volatile oil will also cause loss of aromatic odor due to heat; animal and vegetable glues and some resin drugs After being heated, it is easy to become soft, sticky or melt.
When the temperature is between 20 and 35 degrees, some medicines such as insects, mildew, and degeneration will be produced because they are conducive to the breeding of insects and molds.
Humidity: Humidity refers to the degree of water vapor content in the air, which is the degree of air humidity. Whether the drug itself can maintain normal water content is closely related to the humidity of the air. The normal water content of general drugs is about 10~20%. If there is much water vapor in the air, if the medicine absorbs a large amount of water and the water content increases (wet), it will be prone to mildew and deterioration.
Air: Air contains a variety of components, of which oxygen is most likely to chemically change with certain components of the drug, affecting its quality. The color often seen in the paeonol, Huang Jing, etc., is deepened because the enamel, oil, sugar, etc. contained in them are changed by contact with oxygen in the air.
Daylight: Sunlight has a destructive effect on the pigments and chlorophyll of certain herbs, which can change the color of herbs. Therefore, red and green herbs should not be exposed to sunlight for a long time.
The main methods for the preservation and maintenance of various medicinal herbs:
Easily Insectable Medicines: In addition to diligent inspections of pest-prone medicinal materials, we must start from eliminating pest sources, controlling their transmission routes, and eliminating breeding conditions in order to effectively ensure that they are free of pests. Therefore, the storage of such medicinal materials, such as Codonopsis, Coltsfoot, Coix seed, black snake, etc., we must first choose a dry and ventilated warehouse. The dampness of the ground in the warehouse shall be enhanced by ventilation. Lime, ash, charcoal, etc., may be laid on the ground. The height of the bottom of the rack shall be 40 cm or more. It is best to use wood or wood linoleum paper on the wood to facilitate partitioning. tide. In addition, appropriate conservation measures such as sealing, refrigeration, fumigation, and confrontation may be adopted for different medicinal materials to ensure that the medicinal materials are not insects.
Easy to take the oil moldy medicine: The medicine to go oil moldy, directly affect the efficacy, especially moldy serious, can completely lose efficacy. Medicinal materials mold, refers to the parasite and breeding of mold on the medicinal materials, known as "mildew." For the storage of this type of medicine, the most hot stuffy. Such as Achyranthes, Asparagus, Atractylodes, and other misplaced, can produce oil or mildew, it should be placed in a ventilated and dry place, to prevent moisture.
Easily discolored and odor-smelling medicinal materials: Some flowers, leaves, whole plants and fruit seeds are medicinal herbs. Due to the influence of temperature, humidity, air, and sunlight on pigments, chlorophyll, and volatile oil, they are easy to lose their original color and Odor, such as lotus, safflower, cloves and so on. During storage and storage, proper maintenance should be performed according to the different properties and specific conditions of the medicinal materials. The storage place should be dry and cool, and the temperature and humidity of the library should be strictly controlled. Storage time should not be too long, and to achieve first-in first-out. It's best to stack it separately so as not to confuse it with other herbs that have special smells.
Easy to melt, afraid of heat herbs: easy to melt, heat-resistant herbs mainly refers to the lower melting point, easily sticking deformation after heating, or to disseminate the crystals of those herbs, such as Ejiao, catechu, camphor and so on. For such medicinal materials, it is necessary to select warehouses that can always be kept cool and cool, and package the medicinal materials or containers.
Deliquescence and Weathering Medicinal Materials: Crystalline medicinal materials containing salts are gradually melted in wet places or in high humidity in the air. When it begins to melt, it is generally referred to as "flood" or deliquescence, such as Glauber's salt. For such medicinal materials, warehouses that are cool, sheltered from wind, and protected from light should be selected, or stored in suitable places in the house; packaging materials should be suitable for moisture-proof and non-ventilation.
Pharmaceutics requiring special custody: The venom drugs, flammable drugs, and valuable drugs should be kept according to their special nature and related management measures.
