Goldenseal contains a variety of different active compounds, such as berberine, canadaline, canadine, and hydrastine. It is thought that these compounds are probably responsible for most of the medicinal properties of the plant. There is some concern that the active compounds are too poorly absorbed to have significant medicinal effects when the herb is taken by mouth.
It is unknown if goldenseal is beneficial in children. More importantly, children are often more susceptible to the toxicities of medications or supplements, including goldenseal. Never give goldenseal to an infant or young child, as it is possible that it could increase the risk of kernicterus (brain damage related to severe jaundice).
Do not give your child any medication or herbal supplement without the approval of your child's healthcare provider.
