The course “Plant Remedies” introduces the most important methods of extractions and some forms of preparation of certain remedies. Although it can be understood as a continuation of preceding courses like “Plant identification in one weekend” and the sequel “Signatures for interesting plant constituents”, it can be taken on its own and independently.
We will collect some plants like narrow-leafed plantain outdoors that are later used for making certain applications in the lab. We will isolate plant constituents by extraction with water, ethanol or oil and then preserve them in simple lotions, teas (hot water extract) or tinctures (alcoholic extracts). We will also demonstrate common methods like maceration, enfleuration and distillations.
Student learning objectives
We recommend students have an illustrated book about the wild life flora of the Pacific Northwest (recommended is Pojar and McKinnon “Plants of the Pacific Northwesrt Coast” and R Taylor “Northwest Weeds”) to bring it. Some handouts will be provided. You should also bring a hand lens, a simple folder or plant press to collect plant samples for later identification or preservation).
This course requires a $10 lab fee to be paid to the instructor at the beginning of the course.
Please note this course is both in the classroom and in the woods. Please wear or bring closed-toed shoes appropriate for walking in the woods.
Bastyr University is housed in an older facility with fluctuating interior temperatures; it is advisable to wear layers. Also, Bastyr is a “fragrance-free” campus.

Instructor: Rainer Stahlberg, PhD
Rainer Stahlberg is a plant researcher. He received a PhD in plant biology in 1979 working on electrical signals in plants. Rainer taught botany in Germany (Humboldt University Berlin), Russia (st. Petersburg), and the United States (University of Washington and Bastyr University). He also taught Botany together with the legendary Arthur Kruckeberg to public audiences enrolling for weekend classes with the North Cascade Institute. Arthur introduced Rainer to the plants of the Pacific Northwest from 1998 to 2006. He also imparted his philosophy that science does not exist in a ivory tower or university and that it is the duty of its participants to report back to and serve the public. Rainer has taught botany to kids; major and non-major students and normal people and he I developed a hands-on approach that can be understood by anybody anywhere.
