This seminar was originally recorded at Bastyr University in April 2012.

This home study provides a review of the research conducted on herbs in the past year - not just on the popular and well-known herbs, but also on quirky and less-well-known ones.

The research focuses heavily on human reports, and only mentions preclinical work when it is particularly relevant. How to apply such findings in practice is emphasized including doses, safety, and individualization of therapy to particular patients. Additionally, Dr. Yarnell will discuss what herbs he has seen to be particularly effective in his practice, yet research is lacking.

Ecological and quality control issues for each herb are discussed to improve sustainable use of herbal medicines. There will also be a comprehensive review and discussion of the effects of herbs on cytochrome P450 enzymes based on clinical trial results, and the implications for drug/herb interactions, updated for 2011.

In addition, tools for becoming a more skilled prescriber of herbs will be provided, including improving the ability to formulate effectively. These include a tutorial on the use of a spreadsheet tool developed in Dr. Yarnell's practice that facilitates  blending of liquid extracts as well as herbal teas (the spreadsheet will be provided).

Example cases from Dr. Yarnell's practice are presented, each with interesting outcomes or illustrating important points. Appropriate dosing, safety measures, and duration of treatment are discussed for crude herbs and herb extracts for common and uncommon conditions. Additionally, practical pointers are provided throughout on how to make herbs available to patients affordably and get the results desired, as well as when herbs really aren't appropriate.
