Ginseng also has a shelf life. Dried ginseng usually has a shelf life of 2 to 3 years. Fresh ginseng has a shorter shelf life and is recommended to be consumed as soon as possible after purchase. Dried ginseng is fresh ginseng dried in the sun or dried, dehydrated and then sliced. The maximum shelf life of dried ginseng is generally 3 years, but the longer it is stored, the weaker the ginseng’s efficacy will become. Dried ginseng is usually stored at room temperature or in a freezer. Room temperature storage is stored in a closed cylinder or box, and put the right amount of desiccant at the bottom to keep the storage environment dry. Then the ginseng will be carefully wrapped in a plastic bag and put into the lid closed. For freezer storage, ginseng should be sealed with plastic bag and put into freezer for refrigeration. If ginseng has moldy spots or expired, it is better to consult a Chinese medicine practitioner before deciding whether to use it or not, do not take it by yourself to avoid causing adverse reactions.
