The phrase "cure all" refers to a medication or remedy that is believed to have the ability to cure a wide range of illnesses or health problems. However, there are many synonyms for this phrase that can be used interchangeably, such as panacea, universal remedy, elixir, heal-all, cure-everything, and magic bullet. All of these synonyms describe something that has been considered a universal cure, but none of them have been proven to actually be a cure-all. It's important to be cautious of any remedy that claims to be a cure-all, as there is no such thing as a one-size-fits-all cure for every ailment.
