How does eating possum alleviate leg cramps. Back on the island we ate possum and were happy to do so, but the island was a clean environment. Since moving to the mainland we've found that eating possum is generally frowned upon as the possum is a scavenger that carries disease and who knows what else. I still don't understand how eating possum cures ..... What's that you say???? Potassium???? Not Possum********** ..... Uhm .......Oh......Nevermind!
