The first is to look at the appearance:

Authentic Ejiao is tan or brown-black, smooth in shape, smooth and shiny on the surface, and its edges are translucent when viewed from the light; false ejiao is usually dark in color and has no luster, and its surface is not smooth or even has pits.

The second is using handkerchiefs:

The authentic texture of Ejiao is brittle and hard, it won't bend when broken, it is easy to break, and there is no void in the cross section. But the texture of fake ejiao is not brittle, easy to bend, hard to break, and the cross section is sticky and sometimes has small holes.

The third is the smell:

Authentic donkey-hide gelatin has a slight soy oil aroma and a slightly sweet taste; false ejiao has a strong acrid smell.

In addition, there is a small trick, the E-Jiao after mashing with boiling water, the authentic Ejiao liquid clear, false Ejiao is turbid or even milky.

Experts reminded that we must go to the regular pharmacies to buy E-Jiao and retain the purchase credentials, and follow the instructions of the doctor before taking it, because E-Jiao is not suitable for everyone. When suffering from colds, coughs, diarrhea and other symptoms or positive physiological period, you should stop taking E-Jucco, and people with weak spleen and stomach are not suitable for taking, especially those who suffer from indigestion and gastrointestinal discomfort.
