Marigold 
(Calendula officinalis)

     This is another plant so decorative and common in the garden as to make it seem an unlikely medicine. Nothing could be further from the truth. It is anti-bacterial, antifungal, anti-inflammatory, vulnerary (to be given internally and externally) and, given internally, is a powerful digestive. As calendula lotion (used in homoeopathy and herbal medicines) it is an in valuable wound treatment, disinfecting and stimulating healing in a seemingly miraculous way.
