市场上销售的小茴香掺有两种伪品:莳萝子和瘪谷,它们的形态特征十分相似。对瘪谷,人们一般都能识别;对莳萝子,人们就难以辨认,历史上也把它称作小茴香,亦有广西、甘肃等部分地区把它当作小茴香用,但它确实不是小茴香,并且它们化学成分完全不一样。 The fennel sold on the market incorporates two counterfeit items: dill and defoliation, and their morphological characteristics are very similar. People in the valley are generally identifiable; for dill, it is hard for people to identify. In history, it is also called fennel. Some areas such as Guangxi and Gansu also use it as fennel, but it is not true Fennel, and their chemical composition is completely different.
