Very true. I've been doing it my whole life and have taught foraging here in the UK for a number of years. mainly teaching youth though. Mycology is my real passion when it comes to wild edibles in truth. Some have medicinal value, but more can be found in plants in that regard. After a life of working in medicine I have always wondered what would happen if our ability to provide modern health care as we know it broke down. Or became to strained to provide standard care and could only provide treatment to those in critical care. But for the most part foraging, wild medicine, and mycology are excellent ways to add a special sort of enjoyment to quite woodland walks. Thank you for reading. :)
