Knowing sports are highly ritualistic and superstitious I ask my informant, a football player of many years if he had any experience with folk remedies. This is what he said.
“For football, we all drink pickle juice before a game or in the middle of it because it stops cramps, like we fill Gatorade cups full of pickle juice. The salt helps absorb water because of the salt. Or eat mustard, it has the same effect. Our trainer has us do it. Cramps will make a player come out of the game, it sucks to come out, so we try to prevent them or make them go away so we can get back out there. Cramps are a stupid way to leave the game so yo drink pickle juice. You get used to the taste, it’s not great, but you chase with gatorade, but it’s worth it. It also works, I mean if it’s between taking a shot of pickle juice or not playing we would all take the pickle juice because paying is important. And it works”
Usually folk remedies turn into scientific remedies and vice versa. Or often they are placebo effects, and people believe that what they are doing will cure them. Neither are truly the case here. This is simply a long standing practice in sports where there is a lot of quick actions and muscle cramps are common. Salt does help reduce water in a body’s system, but it is unclear whether it truly helps reduce cramps. It may just all be in the mind or it may not. However, the players believe it, the trainers believe it, so it works. It’s a folk remedy that works for this team and many, but is not a part of conventional western medicine. However, someday it may evolve into western medicine or some medical product may be on the market for muscle cramps, but this team uses pickle juice. Pickle juice isn’t sold to reduce cramps, in fact just pickle juice isn’t sold, pickles are sold then the juice is re-appropriated for medical use.
