Wouldn't worry about it, that's what you get for googling. When I did, I found this. Good job because I eat it everyday and have through all 4 pregnancies.
Basil is a pregnancy superfood. This fresh herb is a good source of protein, vitamin E, riboflavin, and niacin; plus, it?s a very good source of dietary fiber, vitamin A, vitamin C, vitamin K, vitamin B6, magnesium, phosphorus, potassium, zinc, copper and manganese.
Basil is also packed with iron, vital for keeping your energy levels up; calcium, essential for strong bones and teeth; and folate, vital for many processes, including fetal cell growth and division. (One serving of basil has 20 micrograms of this B vitamin.) Whenever possible, choose fresh basil, because it contains more of these nutrients than dried basil.
