Yarrow for Multiple Sclerosis

A 2019 study found that yarrow significantly decreased the annual relapse rate more than placebo over 1 year, in addition to standard treatment, for people with relapsing-remitting multiple sclerosis. The 500mg daily dose of yarrow also significantly decreased the mean volume change of lesions on MRI (magnetic resonance imaging). Yarrow improved cognitive performance and increased time to first relapse compared to placebo. Yarrow is not safe to use in pregnancy. Yarrow can cause an allergic reaction, digestive issues or other side effects.
