What is carters little liver pills?

Carter's Little Liver Pills were a branded over-the-counter medicine marketed as a remedy for various digestive issues, including constipation and indigestion. They were first introduced in 1868, and their popularity grew in the early 1900s through aggressive advertising campaigns. The pills contained a combination of podophyllin resin, aloin, and phenolphthalein. However, the use of Carter's Little Liver Pills became controversial in the mid-1900s due to the potentially harmful effects of phenolphthalein, a laxative that was later found to be a carcinogen. The pills were eventually pulled from the market in the 1960s.
