My brother and his wife recently had a baby. The baby is 3 months old and they are strong believers in alternative medicines. They've been giving her Nux Vomica for the removal of toxicity or something to that effect and all of the research that I've seen has stated that Nux Vomica is extremely dangerous for babies to take. I am concerned about them administering this to an infant, but thus far they've not been listening to my concerns. Is Nux Vomica as dangerous as I'm seeing on the internet?
