    Yes. Keep Chinese medicinal materials such as ginseng and ejiao at home for a long time, and think that the longer you leave them, the better the tonic effect. In fact, this practice is wrong, once most of the herbs have passed the expiration date, not only the effect is greatly reduced, but also whether they can be used or not is a problem.

    For herbal medicines like ginseng, the longer it grows in the ground, the better it may be. However, once it is dug up and made into decoction pieces, the medicinal effect will decrease with the passage of time, and the shelf life is generally not more than 2 years. For example, if ginseng is stored for more than 1 year, 20%-30% of the active ingredients will be lost; If rhubarb is stored for more than 5 years, almost all of its medicinal effects will be lost.

    The same thing happened with woody drugs. Angelica, wolfberry, etc. contain a lot of fatty oil, mucous sugar, although it is not easy to be eaten by insects, but it is easy to "go oily" for a long time, and oil-like substances will appear on the surface. Herbs containing volatile components such as peppermint, herbs, and perilla can be stored for too long and the aroma will affect the quality, thereby reducing the efficacy.

    As for the molecular formula of mineral drugs such as keel and saltpeter, it is not a big problem to put it for a long time. In general, the storage period should not exceed 10 years.
