Honestly, parijat is a strong herb and there is not enough safety data for pregnancy. It is best to avoid it completely unless your gynac explicitly says it's fine. Always safer to stick to regular foods right now.
I would highly recommend staying away from parijat leaves or tea right now. Pregnancy is not the time to experiment with raw ayurvedic herbs. Just stick to your prescribed vitamins and standard diet.
Bro, I barely had energy to drink normal water during pregnancy, let alone exotic herbs like parijat! Jokes apart, please avoid any strong herbal concoctions right now. Your stomach is already sensitive, why risk it?
Why do we always want to try mysterious herbs only when pregnant? Better leave the parijat for beautiful garden vibes and skip consuming it. Talk to your doc if you are looking for specific joint pain remedies.
