How long is the shelf life of Chaga essence products and Chaga raw materials? What should I pay attention to?

First of all, let me talk about Chaga raw materials, that is, seeds collected from birch trees, which have a shelf life. Studies have shown that Chaga is very active, and it can remain active on dead birch trees for 5 to 6 years. The collected Chaga seeds will lose the activity of their useful substances and eventually become "wooden bumps" with no medicinal value. Therefore, it is suggested that the shelf life of Chaga seeds should be 2 years, and they should be stored in a dry and dark environment, and used as soon as possible or used in the production of deep-processed products of Chaga. Let's talk about Chaga's finished product first. Take the original imported birch extract from Beijing Siberian Chaga R&D Company as an example. The shelf life is two years. It is a product refined by modern technologies such as ultra-micro cell wall breaking, supercritical low-temperature extraction and low-temperature vacuum drying. Keep away from the air, drink with warm water, and don't touch metal substances during use.
