Assuming you are referring to the common wasabi plant (Wasabia japonica), then no, it is not safe to eat during pregnancy. This is because the plant contains compounds that can stimulate uterine contractions. In large enough quantities, this could lead to premature labor. Additionally, Wasabia japonica contains compounds that can act as blood thinners. This could increase the risk of bleeding during pregnancy, which can be dangerous for both mother and child. If you are pregnant and crave the taste of wasabi, try using horseradish instead – it’s a similar root vegetable with a similar flavor profile.
