Are there any Igbo Nigerians that know of the clay nzu?

Question

I want to know if consuming it is bad for health, because my mom eats it all the time.

Answer 1

Sorry I am not an Igbo Nigerian, I am from Singapore but these articles have good information:  please tell your dear mother to stop eating it as it is high in lead.
