I’m a big fan of natural things that help make you feel better, and many people already know about echinacea that comes from the purple coneflower. There will always be scientific debate over how effective these natural cures can be. Our ancesstors used natural cures and some do work just like some don’t but that’s true with medicines too,
I know from experimenting on myself that echinacea, astragalus and some types of mushrooms certainly kick in the immune system or mine anyway. They can also give you a yeast infection just like antibiotics though. So if you are the kind of person that keeps a bottle of echinacea in your medicine cabinet, I recommend adding some reishi and shitake mushrooms to the mix along with astragalus. That will help keep down the yeast infections.
