Background
The informant is a first generation Mexican-American student. She said that she spends a decent amount of time in Mexico still (she usually visits a couple weekends during the school year and goes for slightly longer periods during the summer). She visits a lot of family in Mexico, including her grandma, a lot of cousins, and aunts and uncles. She learned this folk remedy from her grandma during these visits.
Context
The informant said that her grandma would use this folk remedy every time her or one of her brothers or cousins got sunburnt. She said that this was a fairly regular occurrence around her grandma, as she lived in a part of Mexico which was much closer to the equator where the sun was more intense.
Text
When we would get sunburnt, my grandma would take the green goop from the inside of the cactus and rub it on our skin. I don’t know if it actually helped or anything… I think it might have… Anyway, uh, she.. It was, like, very slimy. And she did it all the time.
Thoughts
This folk remedy for sunburn seems to come directly from the terrain of Mexico, where cacti are very prevalent. It makes sense that her grandmother would learn and perform folk medicine that is readily available in the region where she lives. Furthermore, when I was collecting this piece of folklore, I realized that the informant seemed to look very fondly on what good be unpleasant memories of sunburnt skin. For the informant, this performance of folk medicine probably also recalls for her some of the comfort her grandma provides to her.
