Back in 1971, Dan Jason published Some Useful Wild Plants; A Foraging Guide to Food and Medicine From Nature, a book that eventually sold over 30,000 copies and became one of the best known books on foraging for wild plants in Canada and the northern United States.

Now, with foraging for both food and medicinal plants, as well as interest in First Nations ethnobotany, reaching widely into new and previously uninterested segments of society, Harbour Publishing has released a revised edition of this classic work.
