TANSY RAGWORT Side Effects & Safety
There’s a lot of concern about using tansy ragwort as medicine, because it contains chemicals called hepatotoxic pyrrolizidine alkaloids (PAs), which may block blood flow in the veins and cause liver damage. Hepatotoxic PAs might also cause cancer and birth defects. Tansy ragwort preparations that are not certified and labeled “hepatotoxic PA-free” are considered UNSAFE.
It’s also UNSAFE to apply tansy ragwort to broken skin. The dangerous chemicals in tansy ragwort can be absorbed quickly through broken skin and can lead to dangerous body-wide toxicity. Steer clear of skin products that aren’t certified and labeled “hepatotoxic PA-free.” There isn’t enough information to know if it’s safe to apply tansy ragwort to unbroken skin. It’s best to avoid use.
Special Precautions & Warnings:Pregnancy and breast-feeding: It’s UNSAFE to use tansy ragwort preparations that might contain hepatotoxic PAs during pregnancy. These products might cause birth defects and liver damage.
It’s also UNSAFE to use tansy ragwort preparations that might contain hepatotoxic PAs if you are breast-feeding. These chemicals can pass into breast-milk and might harm the nursing infant.
It’s not known whether products that are certified hepatotoxic PA-free are safe to use during pregnancy or breast-feeding. Stay on the safe side and avoid using any tansy ragwort preparation if you are pregnant or breast-feeding.
Allergy to ragweed and related plants: Tansy ragwort may cause an allergic reaction in people who are allergic to the Asteraceae/Compositae plant family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many others. If you have allergies, be sure to check with your healthcare provider before taking tansy ragwort.
Liver disease: There is concern that the hepatotoxic PAs in tansy ragwort might make liver disease worse. Stay on the safe side and avoid using any tansy ragwort preparation if you have liver disease.
