David said: Yes I have used herbs to lower fevers, although they do not always work. I think the key is fever management, if the child is hot and throwing off the covers with a fever of 102 or less, then you use febrifuge herbs (Meadowsweet, Black Birch, Huang Qin, Honeysuckle Flower, Mulberry Bark ), if they are cold, chilled with a fever of 102 or less then you use diaphoretics (Yarrow, Pleurisy root, Saffron, Cayenne in Lemonade, Safflower). If the fever is over 102.5 and they are still cold, then the body wants the fever to go higher and that is when you use OTC antipyretics. In addition to herbs, cool baths, cold foot baths, cold compresses can help, here is a Naturopathic guide to hydrotherapy for fever management
