Generally speaking, saffron with good quality will have different shelf life. Generally, good quality saffron can be stored for more than 2-3 years, while poor quality saffron can only be stored for several months to 1 year.

If saffron silk has been preserved for about 5 years, it is generally considered to have exceeded its shelf life. The difference between Chinese herbal medicines is that even if the shelf life has exceeded, they are still well preserved and there is no deterioration reaction. They can still take it, which is not expired.
