Hello I am nine days late on my period. I have heard neem can be taken to cause abortion. I have been taking neem for five days. Will neem leaf cause an abortion?

You really need to ask these question of your own medical practitioner.

Well here in the us neem isn't commonly used I'm trying to get advice from someone in indiz who is familiar with neem. Thank you
