Is this toddler-safe to use Comfrey Root?

🚨
NOT RECOMMENDED
Danger Score: 7 (Lower is safer)
Quick Answer: Comfrey Root not recommended for 1-2 year old toddlers when used in topical products. Watch for toddler-specific sensitivities.

ℹ️General Overview

Comfrey root is not recommended for toddlers (1-2 years). It can carry plant chemicals that may get into the body through the skin and harm the liver. There are also animal studies showing a cancer risk.

What to Do

Do not use products with comfrey root on toddlers unless a pediatrician specifically recommends it. Avoid using it on broken or irritated skin. If a healthcare provider allows short-term use, try a very small patch first, stop if any redness or irritation appears, and do not use repeatedly or over large areas.

⚠️Warnings

Watch for signs of liver problems such as unusual tiredness, yellowing of the skin or eyes (jaundice), dark urine, stomach pain, or loss of appetite — seek medical care if these occur. Sources behind these warnings include government safety advisories and human case reports of liver injury linked to comfrey, and animal studies showing tumor risks. Because of contamination with pyrrolizidine alkaloids and documented liver harm, treat comfrey-containing products as potentially unsafe for young children.

Safety Risk Labels

This ingredient has the following documented risks:

Cancer: Animal and laboratory studies show comfrey (and extracts) can cause tumors and mutations, and a U.S. federal health agency has advised removing comfrey products because of possible cancer risk. This evidence means comfrey root is linked to cancer in long-term tests.
Organ Risk: There are multiple human case reports of serious liver damage (hepatic veno-occlusive disease) after using comfrey, and health authorities list comfrey as a known human liver toxicant. That makes liver harm a real risk if this root is used.
Absorbed: The ingredient can be absorbed through skin and the product notes enhanced skin absorption. Because toxic pyrrolizidine alkaloids are present, topically applying comfrey can let harmful compounds into the body.
Long-Term Risk: Studies show tumor formation at low doses and cases of liver disease after exposure, and health authorities have warned about removal from the market—together this points to risks that can appear after repeated or long-term use.
Banned: A U.S. federal health authority has advised manufacturers to remove comfrey products from the market, and some product-approval programs restrict its use—meaning it is banned or heavily restricted in some places.
