HI
The Amatsu medicine was featured in passing I believe in one of the old books by hatsumi sensei with some cartoon style drawings. I forget the title. they were basically just some stretching and massage techniques.
The Amatsu medicine as stated on MAP has been bulked up in recent times with additional material by the teachers and structured into levels.
Unfirtunately MAP is a junk yard these days. If you notice the moment the Moderator said keep it clean the thread fell to pieces with insults and abuse which is what MAP is only good for these days. The redirection from the thread was a complete joke and another example of 'lets attack someone who is not one of us' . Thankfully a member of the Genbukan did bring it back on track for it to be ripped apart again instantly.
