M.H.
We use it in out home. It is simply food and is perfectly safe for infants as well as toddlers. It actually builds up the immune system so the body fights off the cold, flu or whatever on it's own. My girls used to tell people their mommy had the medicine that Mary Poppins gave Jane and Michael. In liquid form the elderberry is very tasty....No side effects. Unlike standard medicine it doesn't create an environment for other illnesses to attack. Before synthetic chemicals were invented, this would have been the medical doctor's prescription.
Hope this helps.
