Yes, steer well clear of snakeoil like this. Chinese herbs are contraindicated in ivf cycles and may actively act against the medications you will be using for a cycle (e.g. FSH meds etc) and run the risk of potential failure.
Stick instead to healthy diet, marilyn glenville or zita west fertility vits good pre pregnancy vitamins e.g. pregnacare. Other things which are more likely to contribute to ivf success are quality of your clinic, and making sure that you and your partner have no other issues that may stop you getting and staying pg. e.g. Thyroid, uterine, sperm, clotting, karytotyping, infection and autoimmune issues.

It sounds so good and very tempting to try anything to help. But stick to conventional meds. and reputable companies who produce supplements.
