I just listened to the respiratory module today – actually multiple times, since I was at work, cleaning a house, and I sometimes miss some and try to catch it the next time around. Anyway, the topics were colds, flu, etc., and echinacea was one of the herbs to use. Doc Jones said echinacea is immune-stimulating and antimicrobial. It shouldn’t be taken if the flu has gone into the lungs as it may worsen a cytokine storm. It is a mild herb so take it with a stimulating herb like peppermint, ginger, cayenne, yarrow… to help your body notice it, and take a tablespoon every three to four hours or so. He didn’t say anything about coughs in relation to echinacea…
