The validity period of Panax notoginseng powder

Recently, many friends have asked about the shelf life of Panax notoginseng powder. As a traditional Chinese medicine with health-care properties, there are undoubtedly many friends who take Panax notoginseng powder every day. For the sake of convenience, some friends will buy a lot of Panax notoginseng powder at one time and store it at home. So how long is the shelf life of Panax notoginseng powder? Let’s find out together with the editor of Bansui.

How long is the shelf life of Panax notoginseng powder?

The general shelf life of Panax notoginseng powder is about three years. In some cases, it can be stored for seven years, but it is generally recommended to take it within three years. Because Panax notoginseng powder is a material, it is easily affected by the natural environment and may become damp or moldy during storage. Therefore, it is generally recommended that Panax notoginseng powder should not be stored for too long.

Unopened or sealed Panax notoginseng powder can be put in the refrigerator. Generally, as long as it is not moldy (mildew, oil loss), it can be eaten. That is, its color and taste will not change much. Of course, it is best to eat it as soon as possible. Its ingredients will be lost over time. If you don't want to eat it, storage is also very important. It is recommended to put it in the freezer.

Generally, when you buy Panax notoginseng, such as Panax notoginseng roots or Panax notoginseng powder, the merchant will actually tell you a relative shelf life. It is best to take it within the shelf life. Although some Panax notoginseng heads, or those like wild ginseng, can be stored directly for three to five years, the longer they are stored, the more the medicinal effects will lose.

Storage method of Panax notoginseng powder

1. Anti-insect storage The storage of Panax notoginseng powder mainly needs to consider the two aspects of insect prevention and water repellency. Panax notoginseng powder contains more sugar and has a sweet taste. Many insects have a special preference for sweet food and herbs. Therefore, the storage of Panax notoginseng powder requires that the Panax notoginseng powder be well sealed, and then stored together with pepper, Poria cocos, Asarum, etc., and the amount of these herbs and food must exceed the amount of Panax notoginseng powder to ensure the anti-insect effect.

2. Preservative storage: Panax notoginseng powder is easy to get damp after being treated with materials. Therefore, Panax notoginseng powder must not be stored in the refrigerator to prevent moisture. It is recommended to pack Panax notoginseng powder in a sealed bag and place it in a dry and dark place.

3. Sun-proof and isolated storage of Panax notoginseng powder is different from other Chinese medicinal materials. Many Chinese medicinal materials can be directly exposed to the sun for several hours when they are damp, and their medicinal properties will not be affected. However, Panax notoginseng powder cannot be exposed to the sun directly. Exposing it to the sun for too long will cause the outflow of many volatile raw materials in Panax notoginseng, and its medicinal effect will also be seriously affected.

How to buy Panax notoginseng powder

To judge the quality of Panax notoginseng powder, you can look at where the Panax notoginseng is produced. If the Panax notoginseng powder or Panax notoginseng manufacturer has its own planting base in Wenshan, Yunnan, the authenticity will be higher.
