Does osage wood make you ill..i have a friend who gets sick for a week after making an osage selfbow.

Amen!
I quickly found out building selfbows is NOT the "spit and whittle" club especially in the winter when you're closed up in the shop.
Dust collection system and respirators are pretty handy when dealing with any wood. Yew can be real nasty.
