A quack doctor medical device that appeared in the late 1800s, these painful looking instruments made all kinds of claims for their curative properties. Apparently sticking a large rubber dildo up your rear-end could cure anything from constipation, piles, and prostate prostate trouble, to nervousness, improve acne and aid restful sleep. Seriously! You'd think the last thing you'd have is a restful sleep after someone had shoved one of those bad boys up your bum.
These things were marketed right into the late 1930s. Then in 1938, a new Federal Law in the United States covered such quack devices, and they became outlawed.
In 1940, a shipment of rectal dilators, was seized at New York and the US Attorney filed libel cases against the company, alleging that they were misbranded. The misbranding allegations related to the claims that the dilators would "permanently" cure constipation and piles, that they had many other benefits including promoting refreshing sleep and improving acne, etc... Also that the instructions advised "you need have no fear of using them too much." The dilators disappeared as medical devices, only to reappear it would seem in adult shops as... Well you know what!
The painful sounding "Recto Rotor" claimed it's, "the only device that reaches the Vital Spot effectively." (What's the "Vital Spot"?) And that, "This picture tells its own story." Yes, yes it does.
