The World Naturopathic Federation represents naturopathic organizations around the world and helps to provide education about the value of naturopathic medicine to the health of all people. With the help of more than 40 naturopathic researchers, practitioners, and content experts, they have produced several rapid reviews on various naturopathic recommendations for acute viral respiratory infections. These include N-Acetyl Cysteine, Vitamin C, Vitamin D, Multivitamins, Zinc, Quercetin, preventative health behaviours, yoga, Echinacea spp, Sambucus nigra, Hendra helix, Honey & bee products, sea buckthorn, and Eucalyptus & Thyme essential oils. You can find these reviews and further resources at http://worldnaturopathicfederation.org/covid-19-resources/.
Of course it must be said that the naturopathic profession acknowledges that at this time there are no proven treatments for Covid-19.
