In Molds, Mushrooms, and Medicines, Nicholas Money explores the vital and complex role fungi play in our lives, both inside and outside the body. He explains how beneficial yeasts aid digestion and how molds and fungi interact with our immune system, maintaining a delicate balance that, when disrupted, can lead to serious infections. Money also delves into our relationship with fungi beyond the body, from their historical and ongoing use in food to their potential in treating conditions like depression through psychedelic mushrooms. Drawing on the latest research in mycology, the book highlights the essential functions fungi perform in ecosystems and their emerging potential in medicine, providing a deep understanding of their profound impact on human health and well-being.
