Japanese Knotweed for Lyme, Inflammation, and Infections with Emily French

What happens when we stop looking at Japanese knotweed as a problem to solve and start looking at it as a teacher?

Japanese knotweed (Reynoutria japonica) is often used as a go-to herb for Lyme disease, but in this fascinating conversation, herbalist Emily French invites us to see this remarkable plant through a much wider lens. From chronic inflammation and joint pain to menstrual stagnation, skin care, and beyond, Emily shares why knotweed has become one of her most trusted herbal allies—and why reducing it to a single use misses the bigger picture entirely.

Along the way, we explore knotweed's role as a blood-moving herb, its powerful anti-inflammatory and antimicrobial properties, and the surprising ways it supports both ecological and personal healing. Emily also offers thoughtful reflections on knotweed's controversial reputation, revealing how this much-maligned plant may have more to teach us about cooperation, resilience, and reciprocity than many of us realize.

Japanese knotweed also makes a delicious wild food! Emily has shared her recipe for Strawberry Rhubarb Knotweed Galette, a rustic dessert that transforms young knotweed shoots into a memorable seasonal treat. You can download your copy here.
