The dosage of donkey-hide gelatin blocks is 3-9g each time, generally about 6g, twice a day. Dong 'e Ejiao Block has no special requirements on the time and method of taking. It is better absorbed when taken on an empty stomach in the morning, and can also be added to soup porridge as food and taken at meals. You can take it before going to bed at night and make a donkey-hide gelatin milk, which has the effect of calming the nerves and helping sleep. In fact, taking Dong 'e Ejiao on an empty stomach in the morning and evening is more conducive to gastrointestinal absorption, but if the stomach feels uncomfortable, it can also be taken after meals. For example, I soaked Dong 'e Ejiao blocks in yellow wine and steamed them directly. My mother made Dong 'e Ejiao blocks into Ejiao cakes to eat.
