Snow pea leaves

A bunch of snow pea leaves lies in the refrigerator for a while. We decide to make it along with a potato. My mom had a tough time in the stomach. I though she was just being disagreeable. Same happened with me. And then some more. It just happened to be a tummy bug in my case with all the 'emptying works'. Now I have a literal bad taste of it, with its disagreeable taste still reeling in my throat after a day or two, unwelcome through belches.
I could now use it as a natural emetic.
