Castor Seed shattered open an touched

In a new house with the family found a box with a seed in it that I busted open, out of curiosity (I thought it was a fake plastic seed with stuffing in it) I busted it open an disinterestedly tossed it into the trash I'm sure I touched the innards of the seed now a day later I stumbled upon this http://www.youtube.com/watch?v=2z35_1e1MtI video an out of curiosity I googled the castor seed an low an behold "That's the seed I busted open" will I be okay? symptoms apparently take a day or more to show I've googled for them cracked open and I've found none which is worrying. Not meaning to intrude I'm just rlly confused I imagine someone here has the castor plant an could elaborate on the situation
