2-5 year old preschoolers • Skin contact product
For toddlers and preschoolers (ages 2-5), comfrey root is not a safe routine skin ingredient. It can carry plant toxins that may get into the body through the skin and harm the liver. Some studies also link it to cancer risk in animals.
Do not use products with comfrey root on children aged 2-5 unless a pediatrician specifically tells you to. Never put it on cuts, sores, or irritated skin. If a product was applied, wash the area and call your child’s doctor if you see rash, itching, stomach pain, extreme tiredness, or yellowing of the skin or eyes. Keep any comfrey-containing products locked away or out of reach.
Main warnings come from government safety advisories and published studies showing liver damage and tumor formation in animals, and the presence of harmful plant chemicals called pyrrolizidine alkaloids. Because of these documented risks, avoid topical use on young children and watch for signs of liver trouble (jaundice, abdominal pain, persistent tiredness).
