Oleander

I got my oleander stumps grinded months ago and and today I blew all the debris into a pile and a piece hit my lip and that was at 4:17 pm today and it’s now 5 I spit as soon as it hit my mouth and I took a shower after I was done. I seam fine now just indigestion and heart rate is slightly elevated but that’s it. Should I have anything to worry about? Also we’re thinking of getting rock to lay down outside to cover and stragglers that we’re left behind because we have 3 small kids and it’s highly toxic.
