Links on Medicinal Plants

There is a huge amount of information about medicinal plants on the web. A lot of it is fluff and hooey; the user must judge VERY carefully the value of the information.

“In this age of rapidly expanding information, we have reached a period where the most important contributions to our knowledge are syntheses of disparate information in diverse disciplines.”

Richard Evans Schultes

“Without recognition of the knowledge and accomplishments of humans in the past and in other cultures, Western scientific discovery is often only rediscovery”

Timothy Johns

Many of these will have links to information about medicinal plants.

Databases and Other Sources of Specific Information

  • The Agricultural Research Service (US government) maintains Dr. Duke's Phytochemical and Ethnobotanical Databases where you can search for specific information on medicinal plants. This takes a little effort to learn to use but is worth it if you're really serious. You can search for all the chemicals reported in a given plant, what plants contain a certain chemical, and many other variations. This is actually several databases cross referenced and linked to each other. The service will provide you with literature references as well. Very Powerful!
  • Dan Moerman's excellent Native American Ethnobotany database.
  • HerbMed Electronic database on herbs.
  • Database on Plant Oils (lots of hard to find information here).
  • Looking for plant identification info for a specific region? Try searching for “digital flora“ plus the region's name, for example, “digital flora texas“.
  • If you are looking for information on a specific plant, try searching for the Latin name, as this is always a unique keyword.
  • One of the best resources for medicinal plant information is NAPRALERT (which stands for Natural Product Alert). There is a web interface for this service which is searchable. You do have to set up an account and pay a modest fee for each citation located.  However, you can see how many hits there are in the database before paying for anything.

“Once again, indigenous peoples in red breechclothes, living deep in the Amazon, had proven to be our equals -- actually our betters -- in organic chemistry”

Mark J. Plotkin
Tales of a Shaman's Apprentice

“Yet there is a shared suspicion around the world that modern laboratories in their narrow search for precisely acting pharmaceuticals may have missed some important aspects of why the ‘naturals’ do work. The erstwhile impurities might be as essential as the concentrated extract. Moreover, the suspicion of ‘something missing’ in modern pharmacy, fully dependent on laboratory products, is accompanied by a growing awareness that our forefathers were anything but fools in their knowledge of drugs, and that traditional medical systems throughout the world contained an enormously sophisticated number of approaches to therapeutics, ‘tested by time’ as it were, through thousands of generations.”
