Effects of mala

Hi i am husband of 22 weeks pregnant wife. Recently my wife kept craving for chong qing grilled fish but we read that the mala seed is containing some kind of toxins that is not good for the baby. But she couldn't resist temptation so we ended up eating it and her stomach doesn't feel good. She felt extremely guilty and keeps crying about it for days no matter how i tried to console her. Is there anything i can do as a husband? Or does anyone have any advice on the effects of mala to the baby?
