Question about jump starting labor.

Ok so I've read a lot about castor oil and the whole reason it is supposed to work is because it causes intestinal contractions and uterin contractions. Well I'm lactose intolerant and I was thinking, since milk makes me use the bathroom like no other, couldn't I simply drink milk? I'm not saying I'm going to try castor oil so please don't jump down my throat about it I'm just asking if milk already gives me diarrhea couldn't I drink milk and it may have a similar effect as taking castor oil?
