Damiana tea to get pregnant??

Erendida
So I live in a really really small town and for some reason everyone is getting pregnant and I been trying to have a baby for about 8 years and still no luck and a lady that was trying for over 10 years just recently got pregnant even though she went to doctor after doctor and they told her that her husband was never going to be able to give her a family because he had a low sperm count but some one told them of Rosemary and damiana tea and they both drinked it in the morning and at night and now they are 5 months pregnant has anybody tried it or have you heard about it??
