Herbalists Mindy & Marc ponder the effects on the brain and the body when one decides between using or losing a particular function. They discuss the merits of exercise, both physical and mental in retaining skills, as well as telling tales of Mindy’s bike commuting. The herb of the podcast is rosemary (Rosmarinus officinalis), and Marc puts on his herbalist cap to give the lowdown on all of her many uses. Mindy discusses an research article in Parasitology Research (2016) 115:225-239, whereby scientists demonstrate that mosquitoes are repelled by rosemary essential oil as well as that of other plants (and in some cases more so than by DEET!) The twosome review The National Audubon Society’s Field Guide to Wildflowers (Eastern Region), and contrast it with other important wildflower guides (including Newcomb’s Wildflower Guide and Wildflowers in the Field and Forest). Marc and Mindy also relay feedback on their first class of the The Trustees of Reservations Master Urban Gardener (MUG) program, where they learned a great deal about soil health from a USDA agronomist. They end the show with a debate on the merits and perils of governments banning foraging, sparked by an article Marc links to in the Worldwide Herbal & Foraging News section of The Walking Herbalist Website. As always, this podcast attempts to provide a voice in the herbalism, homesteading, and self-reliance community. We hope you enjoy it!
