Maca Root while nursing? Maybe TMI

A little about me.... my husband and I have been married for 19 years. Sadly, I have never had much of a sex drive. I am 4 month PP with our 4th child and my sex drive is now nonexistent. I know it’s a mixture of things and that it may get a little better with time but I was looking up things That May help and come across Maca Root. It has great reviews but I’m not sure if it’s safe while nursing. Has anyone talked to their doctor about it? Just curious! I may end up just making an appointment with my doctor and see what he has to say but thought I’d see if you ladies had any advice. I’m not, nor have I ever been, on BC or meds to affect my sex drive.
