Is this safe for adults to use Comfrey Root?
ℹ️General Overview
For adults: Comfrey root used on the skin has known safety concerns. The plant can contain chemicals that can damage the liver and have caused tumors in animal tests. Small, short-term use on unbroken skin has lower risk than eating it, but there is still cause for caution.
✅What to Do
If you are an adult and choose to use a comfrey-containing product: use it only on small, intact areas of skin and for a short time; never put comfrey in the mouth or swallow it; do not use on cuts, scraped, or inflamed skin; avoid frequent or long-term use; choose products from companies that test for pyrrolizidine alkaloids if possible; talk with your healthcare provider before using if you have liver disease, are pregnant, or are breastfeeding.
⚠️Warnings
Why to be careful: case reports and regulatory advisories have linked comfrey ingestion to severe liver damage, and animal studies have shown tumor formation at low doses. The main concern is contamination with pyrrolizidine alkaloids (reported in safety reviews and regulatory notices). These are the sources for the warnings: regulatory health agency advisories and multiple scientific studies and case reports showing liver toxicity and animal cancer findings.
