Does yarrow help reduce skin/mucosal irritations or infection?

In instances of skin or oral/vaginal membrane inflammation and infections, yarrow is frequently combined with other herbs, such as calendula, St. John’s wort, juniper, nettle, marshmallow root, chamomile, and panax ginseng.^[1][2][3][4] In studies using yarrow plus mixed herbs for a variety of conditions (vaginitis, gingivitis, tonsillitis, and atopic dermatitis), only one trial concluded that yarrow combination therapy was more effective than the control/standard-of-care comparator (acute tonsillitis; proprietary combination extract BNO1030; 4 drops administered orally, 3-4x per day for 10 days).^[2] When yarrow ointment was compared to a standard-of-care ointment (5 g ointment applied directly to site, nightly, for 7 days), standard of care was found to be superior to yarrow in reducing the signs and symptoms of vulvovaginal candidiasis.^[5]
