Someone had posted on the Sept POAS thread that hisbiscus is bad for those trying to conceive (and for at least the first trimester of pregnancy) so off I went to Google.
This is what I found at WebMD (which I consider to be fairly reputable):
Special Precautions & Warnings:
Pregnancy and breast-feeding: Hibiscus is UNSAFE to take during pregnancy. There is some evidence that hibiscus might start menstruation, and this could cause a miscarriage. Not enough is known about the safety of taking hibiscus during breast-feeding. Stay on the safe side, and avoid use.
I underlined the part that really stood out to me. Uhhh WOW. How did I not know this before????! Hibiscus is very commonly found in teas and I drink herbal teas ALL. THE. TIME. I have always thought of it as a safe, warming, non-caffeinated alternative to water. So I went to the tea boxes at my desk: raspberry tea – the 1st listed ingredient is hibiscus flower; my favourite apple cinnamon tea – the 4th ingredient is also hibiscus flowers.
Here’s a few more resources:
Live Strong: Research on estrogen, pregnancy and fertility performed at the Guru Jambheshwar University of Science and Technology in India indicate the estrogenic qualities of the tea may interfere with healthy reproductive activity and affect childbearing and female fertility. Side effects from consuming hibiscus tea on the unborn fetuses are unclear.
And this link has a ton more info (really long but very interesting). These paragraphs stood out for me:
Much modern research has shown the flowers to have a post-coital anti-fertility activity. An example is a study undertaken in 1976 that indicated that the H. rosa sinensis flowers possess significant antifertility activity with the effects dependant upon the dose, duration of the treatment and the stage of the pregnancy. The presence of potent anti-estrogenic activity in the flower portion may be the responsible factor in terminating pregnancy.
An antifertility agent can work by any one or combination of factors. These can include, rapid expulsion of the fertilized ova from the fallopian tube or by the tube locking mechanism; as a blastocyst-toxic agent; by the inhibition of implantation due to a disturbance in estrogen-progesterone balance; or through foetal absorption or abortion, perhaps due to lack of supply of nutrients to the uterus and thus to the embryo.
In the light of above observations, it seems probable that the maximum anti-fertility activity occurs via inhibition of implantation. A restriction of oestrogen levels, which is indispensable for implantation, is considered a probable cause in termination of pregnancy. The researchers demonstrated that the herbal extract possesses potent anti-estrogenic property. On the basis of present evidences it seems probable that, the treatment alters, in one way or other, the delicate estrogen-progesterone balance, resulting in termination of pregnancy.
Gah. We are on Month 16/Cycle 17 TTC and I can’t believe that I might have been hindering our efforts all this time. How did I not know this TTC “rule” when we’ve been TTC so long already. This is devastating. My teas are going in the trash today.
Ladies, go check the ingredients in your tea!
