Safety Notes

It is likely safe for most adults to apply yarrow to the skin and to take it orally in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.

Interactions

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse such as:

People taking blood thinners should talk to their doctors before taking yarrow. It may interact with the medicine.
People with allergies to certain plants may have allergic reactions to yarrow.E1-E4
