Welcoming Video (please check this out)
Course overview: The course will be an introductory to intermediate study and practice of herbal medicine distilled from several world systems of healing, particularly traditional Chinese medicine and western traditional herbalism. Traditional medicine and current herbal practice methods will be blended with rigorous evidence-based research.
Growing sustainable medicine and “farm to tablet” or “farm to medicine chest” will be emphasized throughout the course. Students will learn to make herbal preparations of all kinds (tinctures, salves, creams, and dried tea extracts) as well as growing, harvesting, and processing methods.
Matching herbs and herb formulas for each individual is important in herbal medicine and the student will be introduced to traditional diagnostic methods like tongue diagnosis as well as gathering information, considering etiological factors, and choosing the best herbs for easing symptoms and promoting wellness and healing.
This course will be a comprehensive hands-on experience of today’s growing herbal movement. The efficacy and safety of herbal medicine is well-supported by quality research, and today is being widely incorporated in medical practices in many disciplines—i.e. nursing, chiropractic, medical clinicals, hospitals, and of course naturopathic physicians and practitioners of traditional Chinese and Ayurvedic medicine.
Many resources will be shared, and Powerpoint presentations and video lessons will accompany the textbook and other reading assignments.
Student Learning Objectives:
- Students will learn to make herbal preparations of all kinds (tinctures, salves, creams, and dried tea extracts) as well as become familiar with harvesting, and processing methods for personal and commercial applications.
- Students will learn to match herbs and herb formulas for each individual, which is an important part of herbal medicine and increased efficacy and safety with this approach over a more generic one has been reported in the scientific literature.
- Student will be introduced to traditional diagnostic methods as well as gathering information, considering etiological factors, and choosing the best herbs for easing symptoms and promoting wellness and healing.
- Appropriate growing methods for 50 of the most widely-used medicinal herbs will be thoroughly covered and students will learn to match plants together for companion planting, as well as more about the application of organic nutrients, cover cropping, and composting for increased yields of medicinal plants.
- Students will gain experience in literature acquisition, discrimination of high-quality research compared with papers with poor methodology, statistically-underpowered studies, and gain experience in writing a referenced paper.
- Students will gain experience within the realm of natural products widely offered for sale online and in natural food stores for choosing the most effective products at the best value.
- Students will become familiar with natural products chemistry and learn the major classes of active chemical constituents, what menstruums to use to effectively extract them, and learn more about the pharmacokinetics and pharmacodynamics of the major active compounds in plants. Bioenhancers, or herbs that increase the absorption will also be covered.
Prerequisites and Textbooks: No prerequisites necessary. The course will be suitable for beginners with an interest in natural healing with plants in all aspects—i.e. farming, growing medicinal herbs and spices; wildcrafting, medicine-making for home businesses (body care products, teas, tinctures), or as a foundation for eventual further training in a healing art that incorporates herbal medicine. However, some experience and study of herbal medicine, botany, chemistry, human physiology, or traditional medicine is always helpful. Before the class starts I recommend reading through the textbook and write down questions you might have for later. A reading list is at the bottom, and arranged by importance. Reading through some of these will be good preparation for the class. Most of them are available used through Amazon or http://www.bookfinder.com.
The textbook will be Grow It and Heal It by Christopher Hobbs and Leslie Gardner (Rodale Press). Some other key articles will be assigned during the course. Used copies available.
Course Structure: Students will have a list of assignments due each week—reading, short writing assignments, and “labs” to be done in the kitchen, garden, or in some cases in front of the mirror looking at one’s tongue and the tongues of others. Videos and instructions will be available demonstrating some effective methods for medicine-making, harvesting and other hands-on aspects of herbalism. Keeping up week-by-week is important in order to absorb the main points of herbalism. Dr. Hobbs will offer pre-arranged “office hours” by appointment to answer questions.
