Herbs to Avoid during Pregnancy

In every field of medicine, nutritional supplementation has come to play a central role in our daily health regimen. Now more than ever, nutritional supplements have taken center stage in the realms of fertility health and infertility therapy. Validated by science, new fertility-enhancing supplements are leading to dramatic increases in conception rates and providing a healthful alternative to conventional infertility treatments.

Fertility supplements often include fertility supporting herbs like vitex agnus castus (or chasteberry), as well as green tea, red clover blossom, as well as a number of other ingredients that have been scientifically established to support reproductive health.
