Washington Times 1906.

There was a weird period between about 1900 until the first Pure Food act (which actually didn’t affect most of these laxatives…they were naturopathic quackery, but they didn’t usually have serious drugs in them) that “biliousness” was considered a major cause of headaches, and tons of cures for constipation were marketed as headache cures. The concept and marketing of laxative headache cures was around for a long time before it exploded at the turn of the century, and actually was still not terribly uncommon even after the explosion died down…there are some fantastic retro ads for laxative headache cures from the Golden Age of radio.
