Not safe.
A 5-yuan bag of donkey-hide gelatin dates has to be judged from its packaging, quality, and ingredients to determine whether it is safe. The only sure thing is not to expect what kind of efficacy and effects it has.
First of all, the low price directly determines its quality. The red dates it uses are definitely not very good, and for a bag of red dates that costs 3 yuan, you don’t have to expect it to contain donkey hide gelatin, and If you buy something from a brand you don’t trust, there may be security issues with it.
