Is yi mu cao helpful to a woman trying to conceive and is it good to use?

Don't know but ...: Have you and your significant other had a fertility work up yet? Sometimes the "problem" doesn't reside in the female side of the couple. You should go together to the fertility doc. Another thing you can do is read up on basal body temperature curves. You're only "fertile" 2-3 days a month. The other days are just for pleasure. Best of luck!!
