The broth would be ok while trying to conceive - but I would recommend you back off of any cleansing - including the Hu-Mana-Tea while trying to get pregnant.
This is because the uterus is an organ and when the body cleanses - it will clean EVERY organ - including the uterus.
Cleansing the body to get it into balance is a great thing before having a baby - it allows the body to be in tip top shape for reproduction. BUT - you do not want the uterus to over cleanse - possibly shedding a newly fertilized egg during its attempt to cleanse along with the rest of the body.
When you finish cleansing - just eat healthy, relax and let the body have a chance to rebuild and rebound. It will balance itself out very quickly and hopefully you will have a small one on the way in no time at all.
