The storage time of Chinese medicine in the refrigerator is closely related to the packaging, dosage form and the composition of the Chinese medicine. For substitute decoction, it can be kept for 1 month, and if it is a drinking medicine it can be kept for 1-2 years no problem. Many Chinese herbal medicines with complex ingredients and relatively poor stability can usually be kept for a longer period of time when stored in the refrigerator at 0℃-5℃. If it is an individual processed Chinese medicine pill, using an airtight plastic bottle or plastic bag, it can be refrigerated for about half a year in the refrigerator. In the case of tablets such as ginseng tablets, the storage time is usually up to 2 years when the package is not opened. If the package has been opened, it should be taken as soon as possible. If it is a liquid Chinese medicine preparation, the shelf life is usually 7-14 days when packed in airtight vacuum packaging bags, and it is recommended to take it within 7 days as much as possible. If the herbal medicine contains more scorpions, centipedes and other herbs with high sugar content, the preservation time will be relatively shortened. It is recommended to take the purchased herbs as early as possible, and generally buy as many as you can use. Once the herbs have passed their shelf life, their efficacy will not only decrease, but may also affect your health.
