Popola Plus
A famous feminine hygiene soap that became a massive hit in the Dominican Republic before being banned in 2004. It supposedly disinfected, tightened, and improved the vagina, but the government removed it from shelves for lacking proper permits and having unknown ingredients (popola is a common slang term for vagina).
Many women went as far as to say that thanks to Popola Plus they enjoyed a better sex life because it kept their parts in better condition.
