Mark “Merriwether” Vorderbruggen, Ph.D. is back for another informative class. This time it’s all about medicinal plants. Mark has been a forager all his life. Both his parents were children of the Great Depression and their families foraged to get through those terrible times. Thankfully, this knowledge passed on to Merriwether. Knowing how to harvest nature’s free food fed him through the thin years of childhood and on through getting a master’s degree in medicinal chemistry and a Ph.D. in physical organic chemistry. Since 2008 his website www.foragingtexas.com has been one of the top wild edible plant sites on the internet.
