We hadn't gotten too deep before our guide stopped to pull a snail off one of the trees, calling it a doctor. He turned it upside down and told us to watch before tapping it before the shell filled up with a clear liquid. He poured some of it into his hand before he drank it, saying it was a pain killer and that he could feel his throat turning numb. Then he said give me your hand before emptying the frigid liquid into my palm before I drank. I said it was cold and bitter before asking which part of the snail produced such a remedy. He laughed, put the snail back on the tree and started walking again. I followed.
