Hello, my first post...secondly actually, but now sure where it went. I think i may have been poisoned by my coworker's desk plant. We were debating if it was a Shiso leaf (the edible herb-like leaf adornment found in japanese and maybe vietnamese cuisine. I took a piece of leaf and mash it in my mouth (tongue) I spat out most of it due to discomfort, and where it was resting on my tongue it immediately turned red. It's over 2 weeks later and the red splotch on my tongue has gotten larger and i'm exeriencing a host of other problems elsewhere in my body. Kidney maybe (drinking tons of water, nervousness and anxiety.) I'm desperately hoping someone can help me identify so i can proceed further. I am in really bad shape right now and if you guys can help me with would be appreciated. Thanks.
