Query: DANGER

Besides other potentially harmful ingredients, this product contains Comfrey, which is a known liver toxin EVEN WHEN only applied to the skin (especially over a long period of time). Physicians warn severely against even topical application of this substance. I would avoid this moisturizer until they get rid of obvious toxins that shouldn't even be applied to the skin, like this one.
