Self inducing?

Someone help educate me please.

So I read that castor oil is dangerous to use to try to induce labor. (Because it can make the baby poop inside and later inhale it during delivery)

So what’s the difference with trying to induce labor with raspberry leaf tea, evening prim rose, bouncy ball, etc?

Sorry for being so ignorant. FTM and I don’t get how one method is dangerous but the others are okay to try?

Also when would be the appropriate time to try these methods? I see people drinking the tea in second trimester, but it’s used to kick start labor?

I’m so confused..

Edit: I’m not wanting to self induce or try to jump start labor. I was just curious why one method is safe and one isn’t. I’m letting baby cook as long as needed.
