Dong 'e Ejiao is a well-known listed company, and its production has strict requirements on water quality, donkey skin raw materials and technology. Among many Ejiao enterprises, only Dong 'e Ejiao is a brand enterprise with a history of thousands of years. At present, Dong 'e Ejiao alone has 13 donkey breeding bases in China, meeting the demand for unique resources of genuine medicinal materials. Dong 'e Ejiao is the most authentic Ejiao on the market. Many fake Ejiao are mixed with leather glue, Niu Pijiao, pigskin glue and even Ejiao mixed with plastic. These fake and shoddy Ejiao seriously damaged people's health. The real Dong 'e Ejiao is now anti-counterfeiting. You can go to official website or call the official number to check the authenticity through the serial number on the package or 16 ID number. Fake Ejiao usually looks dull, the surface is not smooth, and some have concave holes, which are not suitable for breaking or even bending. Authentic Ejiao is a brown rectangle or square flat block, with flat appearance, smooth surface, neat corners, luster, translucent and fragile edges when it is transparent. Fake donkey-hide gelatin has a bad smell. You have to smell the glue directly, preferably broken into powder, while the authentic Ejiao has a glue flavor.
