At the Wild Cooperative Permaculture Demonstration & Educational Site, Crawford, CO 

AUGUST 14-15, 2021, 10 AM UNTIL 5 PM – Attend 1 or both days!

Join us for a weekend exploration of the Rocky Mountain fungal kingdom with clinical herbalist Dr. Anna-Marija Helt. The weekend will include a mushroom walk to identify our fungal kin using all our senses with emphasis on their habitat, hazards of local poisonous mushrooms, ethical harvesting and reciprocal relationships. There’ll also be time to geek out on further identification techniques using a microscope. We will learn about medicinal, nutritional, and aromatic benefits of local mushrooms and the folklore around them. The class will delve into hands-on medicinal mushroom preparations such as powdered water and double (water and alcohol) extracts with the most common local mushrooms. We will also have mouth-watering discussions on cooking and preservation techniques of edible mushrooms including sampling of some culinary methods. Samples of medicinal and culinary preparation will be shared with the attendees. There will be a conversation about medicinal mushroom industry and understanding of the sustainable sourcing of species as well as specific parts of a fungus.


SATURDAY, August 14TH 10 AM – 5 PM On the first day, we will connect with nature on an easy to moderate hike in the morning through early afternoon. Please, come prepared for hiking in all kinds of weather and bring your own packed lunch. Later in the afternoon, we will make medicinal and culinary mushroom preparations. Optional wild foods-inspired vegan and gluten restricted dinner prepared by Ewelina will be offered after the class for a donation of $10 per meal.


SUNDAY, August 15TH 10 AM – 5 PM On the second day, we will continue our exploration of nourishing, medicinal, and aromatic properties of our local common mushrooms. We’ll have another hands on experience in medicinal mushroom preparations. We will be sharing culinary preparation techniques, recipes, and methods of preserving surplus of harvest. There will be some samples to sink your teeth in and explode your taste buds on – depending on your appetite, you might want to bring your own packed lunch.


ACCOMMODATIONS Tent camping is available on the land for a suggested donation of $10 per night per tent. Also free camping is available on the National Forest land just a few miles down the road.

There is an enormous amount of misinformation out there regarding that safety of herbs that ranges from herbs as completely innocuous to herbs as a danger to be avoided.

This series is to help you wade through it from the perspective of a practicing herbalist and doctoral level scientist with decades of experience either carrying out, reviewing and/or reading/interpreting research studies along with over a decade of experience in clinical herbalism.  Specific topics include:

•  Real world data on herbal safety – a broad perspective 

•  Understanding the highest risks for herb-drug interactions

•  Safety data for the top selling herbs in the US

•  Herb interactions with the p450 family of metabolic enzymes…from speculation to 

    real clinical data

•  Critically interpreting research and case studies 

This class is targeted towards (but not restricted to) healthcare practitioners whether you’re an herbalist, naturopath, nurse, medical doctor, pharmacist, or other of the many others offering support to those who use herbs.
