近来,我司在收购药材中,发现有将蕉藕经精心加工后冒充天麻出售者。现将其真、伪天麻之鉴别点陈述如后。正品天麻为兰科植物天麻的干燥块茎。呈长椭圆形,扁缩而稍弯曲,长3～13厘米,宽2～6厘米,厚1～3厘米。一端有红棕色干枯芽苞,习称“鹦哥嘴”或“红小瓣”,或为残留茎基;另一端有自母麻脱落后的圆脐形疤痕,习称“肚脐眼”。外皮剥落或部分残存,表面黄白色或淡黄棕色,具环节,节上有点状的退化须根痕或膜质鳞叶,春麻多皱纹,冬 Recently, in the acquisition of medicinal herbs, our company has discovered that it has been carefully processed and impersonated as a gastrodin seller. The distinguishing points of its true and pseudo Gastrodia are stated later. The authentic gastrodia is the dry tuber of the orchid plant Gastrodia elata. It has a long elliptical shape, which is deflated and slightly curved. It is 3 to 13 cm long, 2 to 6 cm wide, and 1 to 3 cm thick. At one end, there are red-brown and dry buds, which are commonly known as “paraguai beak” or “red flap”, or residual stem base; the other end has a round umbilical scar after shedding from the mother’s anesthesia, commonly known as the “navel.” The skin is exfoliated or partially remnant. The surface is yellowish-white or yellowish-brown, with a link, a little bit of degraded fibrous root scar or membranous scaly leaf, wrinkled spring, and wrinkles.
