The folk song/chant: “Sana que sana, colita de rana. Si no sanas hoy, sanarás mañana.” (Magic healing song repeated at least three time or more if child is hysterical) The literal translation means “Heal, heal with the tail of a toad, if it does not heal today, it will heal tomorrow.” Obviously they are talking about a tadpoles tail or are being funny because a toad/frog does not have a tail, intonating something magical is about to occur. It works as a great distraction when your child gets injured and to stop him from crying because they are being imbued with the belief that the chant will actually make it hurt less especially if they say it in unison. Although my Grandfather tells me that the Chibcha Indians of Colombia, which he is a ¼, use dried out frog/toads all the time for healing and good luck and would even wear them around their neck (whole died out toad) for protection. He tells me that my mom went to Colombia at age 16 and she was given a necklace made out of small stones, which had a small, carved frog in the middle and was told to wear it for good luck and protection.
Analysis: Many frogs in Colombia have a variety of toxins, some medicinal, some deadly so there is more than simple folk belief there might be some factual basis for the song. Growing up my mother would always do the magical healing song “Sana que Sana” that her dad taught her whenever my brother or I got hurt and sprayed the area with Neosporin. She told me that when she was young, her grandmother (my great grandmother) who was a “botanica healer” would always sing the song while rubbing the injured area with some kind of balm. I do find the song soothing and silly at the same time, which is why it was probably so effective as a distraction. In terms of healing, the balm or Neosporin was probably what made it stop hurting and heal faster but rubbing an injury does stimulate endorphins to alleviate pain but the distraction is extremely helpful in stopping the blubbering and crying.
