Can I eat basil seeds during pregnancy?

Not a good idea. Pregnant women or those trying to conceive should not use basil since it lowers the levels of estrogen.
Not recommended. Although full of vitamins and minerals, it is believed that Basil seeds reduce estrogen levels. Should not be taken when trying for pregnancy or while pregnant.
Limited intake. Some of the oils of herbals can stimulate the uterus and cause contractions. You're probably better off adding some basil to meals instead of ingesting large amounts of it.
