Herbal Induction??

I am 40+3 and yesterday I had my second membrane sweep. Fingers were crossed and I walked for an hour after and had sex and drank my red raspberry tea and took 1000mg of EPO orally and 1000mg vaginally.... STILL NOTHING. 😩 Midwife said on Sunday she can offer me a herbal induction that is lemon verbena and castor oil ever 4 hours for up to 4 doses. Has anyone tried this?? She said it causes contractions and kicks the body into labour for most people. Last resort is a medical induction next Wednesday. This is starting to feel like a never ending story 😩😩😩😩😩
