and there are Wikipedia artcles on the Circa Instans and the AM in the German W. which could be of help as well

Thank you, Helmut. It seems that no online transcription is available, but the second paper you linked provides a list of manuscripts and early printed editions. This book is about compound medicines, hence it fits well the common interpretation of the Voynich "pharma"/small-plants-with-containers section. 
Also in this case, each "antidote" appears to be considerably longer than a paragraph in the pharma and recipes/Q20 Voynich sections.
