Herbs to avoid during pregnancy

Since I am all absorbed in the pregnancy at the moment I found this page to be very interesting.

It tells you which herbs to avoid during pregnancy and some other herbs that can be beneficial. Please be careful, whatever you do. Better to err on the side of caution is my stance on this, anyway.

I am contemplating making my own anti-stretchmark cream from shea butter, tamanu and jojoba oil but I need to find out if the ingredients will make it through the over-zealous customs office first.
