What is the shelf life of Cordyceps sinensis?

Cordyceps sinensis is a medicine we are relatively familiar with, but how long is the shelf life of Cordyceps sinensis? I believe many people cannot answer this question because they are not particularly familiar with this medicine. However, if the person selling this medicine sells expired Cordyceps sinensis, which is a problem that everyone does not know, it will cause trouble to everyone. Therefore, it is very necessary for us all to understand the shelf life of Cordyceps sinensis. Let us now find out how long the shelf life of Cordyceps sinensis is.

The key points in storing Cordyceps sinensis are moisture-proof, moth-proof and insect-proof. Cordyceps sinensis should not be stored for too long, otherwise its efficacy will be reduced. If a small amount of Cordyceps sinensis has a short storage time, it can be kept in a cool place or refrigerated in the refrigerator. If it is stored for a long time, it can be stored together with silica gel desiccant.

The amount of Cordyceps that an average family buys each time will be slightly more than the amount for one dose, so it is necessary to pay attention to the storage of Cordyceps. Since the 1980s, various parts of my country have gradually applied oxygen removal and preservation technology to the storage of Cordyceps sinensis. Studies have shown that Cordyceps maintained using deoxygenation and fresh-keeping methods maintains good quality, is free of insect infestation and loss, during a storage period of up to two years. The key points of storage are moisture-proof, moth-proof and insect-proof. If the quantity is small and the storage time is short, just store it in a cool and dry place. Place it with Sichuan peppercorns or moutan bark in a sealed glass, refrigerate it in the refrigerator, and take it out when needed.

If the quantity is large or the Cordyceps needs to be stored for a long time, it is best to put some desiccant such as silica gel in the place where the Cordyceps is stored, because the newly purchased Cordyceps is a little damp and it is easy to mold and get infested with insects if left for a long time. Cordyceps should not be stored for too long, as its efficacy will decrease. When Cordyceps is exposed to moisture, it will molt, that is, the worm body will become empty shell, and it will become flat after being pinched, and the quality of Cordyceps will be reduced. Experts remind: "The fresher the Cordyceps, the higher the quality. It is best not to store it for a long time. It can be stored for 5 years under vacuum conditions; under normal conditions, the shelf life is only 2-3 years. If it is stored for too long, the active ingredients will be lost."

At the appropriate temperature, mold spores in the air will scatter on the surface of Cordyceps sinensis, absorb nutrients from the medicinal materials, germinate hyphae, and secrete enzymes, further destroying the medicinal materials. If Cordyceps sinensis is attached with insect eggs, they will hatch when the temperature reaches a certain level. Some woodworms can secrete enzymes that break down the components of medicinal materials, causing them to deteriorate and obviously become unsuitable for consumption.

The above content is about the shelf life of Cordyceps sinensis. People who use this medicine must pay attention to the shelf life of this medicine. It will be troublesome if it is used after the expiration. Therefore, if people store a large amount of this medicine, they should pay more attention to observation. If there are any changes, the expired medicine must not be used. After learning about the shelf life of Cordyceps sinensis, I believe everyone has a certain understanding of it and should pay attention when using it.
