日前，美国食品药品管理局发布新闻提醒消费者“目前在市场上销售的、商家自称来自胎盘、所谓“顺势疗法”的人绒毛膜促性腺激素（human chorionic gonadotropin）减肥产品不合法，这一类产品既没有得到FDA的批准上市，更没有该产品生产商家所宣传的如何如何神奇的药理功效。FDA曾经7次致信该公司以示警告，但仍有类似产品在市场上销售，望寻求保健品的朋友们加以注意，以免上当受骗。

The Food and Drug Administration (FDA) is advising consumers to steer clear of these "homeopathic" human chorionic gonadotropin (HCG) weight-loss products.  They are sold in the form of oral drops, pellets and sprays and can be found online and in some retail stores. 

FDA and the Federal Trade Commission (FTC) have issued seven letters to companies warning them that they are selling illegal homeopathic HCG weight-loss drugs that have not been approved by FDA, and that make unsupported claims.
