Is Chaga an effective antiviral? If so, how can we rank the relative benefit of Chaga vs. Anamu and Galangal if cost is a limiting factor?

Chaga does have antiviral benefits, as do the others mentioned here. We would rank it ahead of the others, so we would put them in that order: Chaga, Anamu, and Galangal as number one, then the second and then the third choice, in relative importance overall to the stated goals here of rounding out a basic cocktail of supplements for virus-based and mitochondrial dysfunction-based disorder alleviation.
