Hi all,
Most of what Anna learnt was obviously verbal, as it was a conference. but she has recommended these books for further reading. Martin Powell was the speaker that offered all the advice on Chaga.
For all thing medicinal mushroom, including chaga, try Martin Powell.
1, Medicinal Mushrooms, the essential guide. (a more accessible version for beginners)
2, Medicinal Mushrooms, a clinical guide. (a more technical guide for health care practitioners)
also, for general Medicinal Mushroom info, you can try;
Growing gourmet and medicinal mushrooms by Paul Stamets (as an aside, his book, Mycelium running, is a fantastic read on how mushrooms can save the world).
And if you like Paul Stamets, give this video on medicinal mushrooms a watch

Also, if this is a topic that interests you, Fred Gillam at 'the wild side of life', who organised the medicinal mushroom conference, is planning to do another one next year. i couldn't go this year as i was on call for work, but will be going next year as it sounded fascinating.
hope this helps
