Join us for a deep dive into the remarkable world of lichens — ancient symbiotic organisms that blur the lines between fungi and algae. This class will explore a half-dozen well-known lichens and their diverse traditional and contemporary uses for food, clothing, medicine, dyes, shelter, and even mythology.
● Alectoria – once woven into clothing and explored for use in cystic fibrosis
● Bryoria – a traditional survival food with roles in mythology, medicine, fibre-making, and emerging studies on immune-suppressive and anti-cancer compounds
● Lungwort (Lobaria pulmonaria) – long valued for respiratory health and fibromyalgia, with modern evidence for anti-inflammatory, antimicrobial, and neuroprotective properties
● Iceland moss (Cetraria islandica) – used for dry coughs and bronchial conditions, and researched for anti-Helicobacter, anti-diabetic, and neuroprotective effects
● Peltigera (Dog/Pelt lichens) – known for supporting the liver, vagus nerve, and immunity, and showing antiviral activity
● Wolf lichen (Letharia vulpina) – a brilliant dye source with historical medicinal use, though also toxic
● Evernia prunastri (Oakmoss) – prized in aromatherapy and perfumery, with antibacterial, antihypertensive, and anti-hyperpigmentation actions
● Usnea species (Old Man’s Beard) – three common species will be discussed, with a focus on preparation techniques and the powerful antimicrobial usnic acid
This webinar will cover:
● Understand what lichens are and how they grow
● Recognise where to find them in the wild and whether they are common or rare
● Describe their traditional cultural and medicinal uses
● Identify key chemical constituents and their potential applications in clinical practice
● Discuss safety considerations and toxicity in certain species
● Explore how lichens may act synergistically with modern drugs
“A great introductory. Our we on medicinal mushrooms, their uses and contraindications, well presented with great additional stories, studies, anecdotes and more. Always a pleasure learning from Robert Rogers.”
Magdalena Saito - Vanderhoof, BC, Canada
“I really loved all the information presented in the course. Robert is always such a pleasure to listen to; he has so much knowledge and experience and has a sense of humour that brings a special presence and warmth to his teachings. I’m always inspired after listening to him.”
Elizabeth - Victoria, BC, Canada
“Robert Rogers is an excellent teacher and had a wealth of knowledge and personal stories to share. I think the balance of scientific information and folkloric/cultural information was also excellent. It is a great beginner and intermediate course on medicinal mushrooms—I had taken a few other courses from other people and I did learn new things about old favourite fungi.”
Melissa Bettcher - Edmonton, AB, Canada
