Echinacea and Yarrow kept me from getting Covid, as the symptoms came and went last January.
Echinacea is a basic for strengthening the immune system. Too much of it is said not to be harmful. You have to be careful with Yarrow. I believe l have read that too much Yarrow can be toxic. (I also take communion daily, but that's a different matter.)
