Treatment of the Common Cold with Unrefined Echinacea
A few comments here. First, most commercially available forms of echniacea are standardized for the active components (which is still up for debate…) and not given unrefined. The practitioners using unrefined herbs are very knowledgeable and will use this herb as it was meant to be used–as one component to a multi pronged approach to strengthening the immune system. Personally, I never recommend echinacea. I usually tell patients to avoid refined carbs because they suppress the immune system, drink lots of water and take lots of Vit C (1 gram/hour to bowel tolerance).
