Wisdom from Mimi

"When I was 15, after mowing my Mimi's lawn, I unknowingly drank her wild-harvested Chaga tea. Mimi, who had just been diagnosed with stage 4 pancreatic cancer, was incredibly excited about Chaga, calling it the 'unrivaled King of Herbs.' Witnessing her excitement was contagious. She showed me how to harvest it from a birch tree in her backyard and shared its impressive medicinal history. Soon after, we began harvesting Chaga together and selling it at farmers markets and craft fairs. I carry her gift and the passion she ignited with me every day. Birch Boys started as a healing quest, and that remains our guiding philosophy."
