 But echinacea is wonderful because as Lorna was saying, it's an immune modulator. Otherwise, with normal immune situations where you need a response team quite quickly, it uses resting monocytes and gets them motivated very quickly and going. One mil a day if you're getting older and then more heroic, what we call heroic doses, if you're actually sick of a one-in-one of this blend, take five mils three times a day, five times a day, while you're in the process of trying to motivate that immune system. But if you have a poor immune system... And any kind of immune situation, so someone might have a cold, but actually they might have an upset stomach and they might not know why they have an upset stomach. And we have other herbs that would be almost more specific for that, but you would still use things like echinacea. So it's just almost like you don't really need to know what's wrong with someone.
