Mga mommies. Can i give my 2mos old son oregano juice? He has cough and it worsen because he had fever due to vaccination. Thanks!

I know some mommies give oregano to their babies who are below 1 year old and most of them say that it's effective naman. However, I have read that it's not good for babies below 1 year of age because it contains Vitamin A which is not advisable for infants.
