This episode covers the herb Sumac. This is a delicious middle eastern and African spice, but does it have medicinal properties? Spoiler alert: it does have medicinal properties and we are going to explore them with our usual thoroughness. Besides covering the basics of herbology including category, and functions, we will explore the history, quality, science, pharmacology, evidence, and any potential interactions. And then there is always something a little quirky about an episode: the foundational and very important Yi Jing or Book of Changes. Please join us as we learn about this herb/spice/medicine, Sumac!
