Hello, instead of buying the 6 oz immunity support every month, I am trying to find all the ingredients to buy 1 pound bags and mix my own. Doc, you do not carry CHAGA powder, what can I use instead of it? I have been looking at other plants but you don’t have chaga on our plant list, can you give me a replacement powder that I can use instead? Thank you very much. Still buying from you just want to make a bigger batch! Joanne
