Sue Gilbert Sue is a consulting nutritionist. For many years she worked with Earth's Best Organic Baby Food, integrating nutrition and product development. She has written numerous articles on children's health and nutrition for parenting publications. Dear Yu Yun, Studies are not carried out to test the safety of herbs on babies, and therefore it is not recommended that they are used for them. The pharmacological effect of herbs requires breakdown of them by the liver, and because babies livers are still small and immature, a safe dose for an adult can be dangerous for an infant.
Many herbs are in fact toxic to babies.
Of course there is scads of historical information about the effectiveness of different herbs for different medicinal uses in children, and many folks rely on this information. Also, herbal teas tend to be far less potent than their counterpart in capsule form, and so a cup of herbal tea may be safe, when otherwise it may not be. However, I cannot knowledgeably say to you that a cup of chamomile tea would be fine for your baby. If you think you would like to try such a remedy, than it is very important that you first get the advise of your pediatrician. Until there are conclusive studies that prove that the tea is not only safe, but beneficial, you would be wise to look for more reliable methods to perk up your baby's appetite.
