Yes I have, but the method of preparation is key and it's more of a time issue. Having said that last year I made a bunch of wild mallow capsules to dose through the winter which was rewarding. It is a great idea, but when I decided to try this the time constraints just made buying them easier... mainly due to the sheer quantity I was consuming. But I'm heading out to look for some chaga fungus this weekend so powdered capsules may be my go to if I have any lucky finds. It tends to be more cost effective. Thank you for giving the post a read. :)
