"Medicine Tree" is a work of fiction. All the characters mentioned in it are purely products of the author's imagination.
The geographic locations, on the other hand, are real. They can all be found more or less as they are described in the story.
As for 'Medicine Tree' itself...does it really exist? I don't know. But it's a question that has intrigued me for a long time. Since I couldn't find a satisfying answer, I just made one up. I hope you will enjoy it.
