Asarabacca

Background

Asarabacca is a type of evergreen plant. It grows in Europe and parts of Asia. The root is used to make medicine.

People use asarabacca for conditions such as bronchitis, other lung infections, chest pain (angina), and many others, but there's no good scientific evidence to support these uses.

Don't confuse asarabacca with bitter milkwort or senega. All three are sometimes called "snakeroot." Also, don't confuse asarabacca with coltsfoot or ginger.
When taken by mouth: Asarabacca that is verified as being "aristolochic acid-free" is POSSIBLY SAFE when used short-term. But asarabacca is POSSIBLY UNSAFE when taken by mouth in large amounts or for longer durations. Large amount of asarabacca, even that which is verified as being "aristolochic acid-free," may cause nausea, vomiting, burning of the tongue, diarrhea, rash, and paralysis. Asarabacca that is not verified as being "aristolochic acid-free" is UNSAFE when taken by mouth for any length of time. Aristolochic acid can damage the kidney or cause cancer.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It is LIKELY UNSAFE to take asarabacca if you are pregnant. It might start your period or cause the uterus to contract. These effects might cause a miscarriage. Avoid use.

There isn't enough reliable information to know if asarabacca is safe to use when breast-feeding. Stay on the safe side and avoid use.

Stomach or intestinal (gastrointestinal, GI) problems: Asarabacca can irritate the GI tract. Don't use it if you have ulcers, inflammatory bowel disease, or Crohn disease.
