Southwest Conference on Botanical Medicine Classroom


In this 4-hour pre-conference intensive, Glen Nagel, ND, RH (AHG) covers common concerns about drug/herb interactions for the naturopathic physician and clinical herbalist. The most common types of interactions and methods of drug detoxification are discussed along with a comprehensive five-point system for determining herb and drug interaction risk potential. He describes the top ten herbs for potential interaction and the top fifteen most commonly prescription drugs. Included is an overview of resources in this field for clinicians.

Outline of Main Points
1. With up to 80% of Americans consuming herbs and nutritional supplements, there is an
obvious potential for interactions. For holistic practitioners, what are the real concerns
when combining prescription medication and herbal medicine and what is hype?

2. We discuss the ten herb-drug interactions that every naturopathic physician and clinical herbalist should understand. Herbs discussed are St Johnswort, saw palmetto, milk thistle, goldenseal, cannabis/hemp and others.

3. We describe the difference between botanicals that are cytochrome P-450 inducers and those that are inhibitors, and those that are neutral to the liver detox system.

4. We review 10 herbs and potential for drug interactions of grapefruit, Hypericum, milk thistle, ginkgo, saw palmetto, goldenseal, green tea, black tea, echinacea, and fiber-rich plants. And finally we review the top 15 drugs and potential for herb interactions including Lisinopril, Atorvastatin, Metformin,  Metoprolol, Omeprazole, Levothyroxine, Albuterol, Gabapentin, Acetaminophen, Atenolol, Steroids, Amoxicillin, Cannabis, Hemp and others.
