How does Scarlet Pimpernel work?

Scarlet pimpernel contains chemicals that might have activity against some bacteria, fungi, and viruses. It also appears to have estrogen-like effects and might have negative effects on human sperm.

Are there safety concerns?

Scarlet pimpernel appears to be UNSAFE for long-term use when taken by mouth or applied to the skin. Scarlet pimpernel can cause swelling (inflammation) of the stomach, intestines, and kidneys with long-term use or high doses.

There isn't enough information to know if scarlet pimpernel is safe for short-term use.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It's UNSAFE to use scarlet pimpernel if you are pregnant. It might make the uterus contract, and this could cause a miscarriage. Additionally, long-term use or high doses can lead to swelling of the stomach, intestines, and kidneys. The safety of short-term use is unknown. Stay on the safe side and avoid using scarlet pimpernel if you are pregnant or breast-feeding.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Scarlet pimpernel might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use scarlet pimpernel.

Difficulty conceiving a child (infertility): Scarlet pimpernel might harm sperm. If you are a woman trying to conceive a child or a man trying to father a child, don't use scarlet pimpernel.
