Traditional Chinese medicine has a shelf life code.

If it is a Chinese patent medicine, it usually takes about one to two years.

Chinese patent medicines have a shelf life. As for Chinese herbal medicines, they will deteriorate when they are wet, and they can't be used for a month or two. Because moldy Chinese herbal medicine not only can't cure the disease, but it aggravates it. As for long-term preservation, it must be stored in ceramic utensils and absorbed with lime. Therefore, Chinese herbal medicines should be decocted in time, and the decoction should be kept in the refrigerator like vegetable soup. If you find an odor, please stop taking it immediately.

The shelf life of Chinese medicine is uncertain, and the storage time of Chinese medicine depends on the nature and storage conditions of Chinese medicine. Generally speaking, herbaceous plants do not exceed two years, woody plants do not exceed four years, and minerals do not exceed 10 years. There are also some drugs containing volatile oil, which have a short shelf life, generally no more than one year.
