Background

Marsh marigold is a plant. People use the flowering parts that grow above the ground to make medicine.

Despite serious safety concerns, people take marsh marigold for pain, menstrual disorders, swollen airways (bronchitis), yellowed skin (jaundice), liver disorders, and other conditions, but there is no good scientific evidence to support these uses.
When taken by mouth: Fresh marsh marigold is LIKELY UNSAFE. It can cause diarrhea and severe irritation of the stomach, intestines, bladder, and kidneys. There isn't enough information to know whether the dried plant is safe to take by mouth.

When applied to the skin: Fresh marsh marigold is LIKELY UNSAFE. When marsh marigold comes in contact with the skin, it might cause blisters and burns. There isn't enough information to know whether the dried plant is safe to apply to the skin.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It's LIKELY UNSAFE to use marsh marigold if the plant or plant parts are fresh. The safety of the dried plant is unknown. It's best to just avoid using marsh marigold if you are pregnant or breast-feeding.
