For adults: This comfrey extract may be risky. It can carry plant toxins that have been linked to liver damage in people and to tumors in animal studies. Short, occasional use on unbroken skin is less risky than giving it to babies or using it for a long time, but caution is still needed.
If you are an adult and the product contains this extract: use it only on unbroken skin, do not use it for long periods, and do not swallow it. Stop use if you have any signs of liver problems (yellowing of the skin or eyes, dark urine, unusual tiredness, nausea, stomach pain). Check product labels and prefer products that do not include comfrey extract. If you have liver disease, take medicines that affect the liver, are pregnant, or breastfeeding, talk with your doctor before using.
Main warnings come from reports and health agency findings about pyrrolizidine alkaloids in comfrey and cases of liver injury after comfrey use, plus animal studies showing tumor formation. Because of these documented risks (including an advisory by a major health agency and published case reports), avoid applying this extract to broken skin, avoid long-term or repeated use, and never ingest products containing it.
