牛黄长期以来为紧缺珍贵药材,近年由于中成药用量急增,国产和进口资源有限,致使价格猛升十数倍,不法分子大量制造假牛黄,冒充天然牛黄。自古以来伪造牛黄者屡见不鲜,但多伪造个黄,伪造管黄者实属罕见。近年来管黄上市量成百倍增加。一批可多达数公斤。从收检的数批样品来看均属假造管黄,宏观检查极为相似,真假难辩。为引起人们的重视,防止上当受骗和造成严重后果,特将牛黄经验鉴别的浮浅认识简介如下,供参考。牛黄为牛科动物牛的干燥胆结石。宰牛时如发现胆囊内有牛黄,可滤去胆汁将牛黄取出,除去外部薄膜,用毛头纸或灯心包裹阴干(防破碎)。产地:国产牛黄主产北京、内蒙、辽宁、黑龙江、吉林、山东、陕西、甘肃等地。进口牛黄来自加拿大、阿根廷、乌拉圭、印 Niuhuang has long been in short supply of valuable medicinal materials. In recent years, due to the rapid increase in the use of proprietary Chinese medicines, domestic and imported resources have been limited, resulting in prices soaring more than 10 times. The criminals have made a large amount of fake bezoar, posing as natural bezoar. It is not uncommon for people to forge bovine oxen from ancient times. However, it is rare to forge yellow ones and counterfeit yellow ones. In recent years, the number of listed companies has increased by hundreds of times. A batch can be up to several kilograms. Judging from the batches of samples taken from the inspection, it is a fake tube yellow. The macroscopic inspection is very similar and it is hard to argue. In order to arouse people’s attention and prevent deception and cause serious consequences, the brief understanding of Niu Huang’s experience identification is described below for reference. Niuhuang is a dry gallstone of bovine cattle. If the gallbladder is found to have bezoar during slaughtering, the bile can be filtered out and the bezoar can be removed. The outer film is removed, and dried (wrapped) with torn paper or wick. Origin: China’s main bezoar production in Beijing, Inner Mongolia, Liaoning, Heilongjiang, Jilin, Shandong, Shaanxi, Gansu and other places. Imported bezoar from Canada, Argentina, Uruguay, India
