<<Disclaimer: Verify this information before applying it to your situation.>> Hello I realise that people with celiac disease should not take the herb echinacea because it stimulates the immune system - and apparently our immune system is already stimulated and does not need any more stimulating. However, I am currently taking a homeopathic herbal mixture for energy which contains the astragalus herb. According to my herbal book, that herb is meant to help the immune system, but I am wondering whether or not I should continue to take it. Does anyone know? Thanks Vicky
