Calendula (also widely known as Marigold) is one of the best herbs available for the treatment of local skin conditions, whether they are due to infection or physical damage. A poultice made from a handful of flowers may be applied to injuries where the skin is broken, as well as sores, leg ulcers, abscesses, as well as sore nipples in nursing mothers and grazed knees in schoolchildren. Taken internally, an infusion of the flowers will aid in cases of absent or painful menstruation and vaginal thrush.
