1-2 year old toddlers • Skin contact product
Comfrey extract may carry toxic plant chemicals that can harm the liver and has been linked to tumors in animal studies. For toddlers (1–2 years) this ingredient is risky, especially on broken skin or with repeated use.
Avoid products that list comfrey, Symphytum officinale, comfrey extract, or similar names for children aged 1–2 years. Do not apply to cuts, scrapes, or irritated skin. If a product containing comfrey was used by mistake, stop use and talk with your pediatrician. Prefer products labeled safe for toddlers or ask your child’s doctor for alternatives.
Warnings come from health agency notices and scientific studies showing liver injury and tumor findings tied to comfrey and its pyrrolizidine alkaloids. Watch for signs of liver problems (yellowing of the skin or eyes, dark urine, unusual tiredness, stomach pain, nausea) and stop use and seek medical care if these appear. Also avoid long-term or repeated use on young children and avoid any product with unclear ingredient sourcing because contamination with harmful alkaloids is a known concern.
