Essential Oil and Plant Research Sites

The PubMed search system provides access to the PubMed database of bibliographic information, which is drawn primarily from MEDLINE and PREMEDLINE. In addition, for participating journals that are indexed selectively for MEDLINE, PubMed includes all articles from that journal, not just those that are included in MEDLINE. Finally, PubMed also provides access to the molecular biology databases included in NCBI’s Entrez retrieval system. It is expected that access to additional National Library of Medicine databases will be added in the future. CAM on PubMed
CAM on PubMed, a database on the Web developed jointly by NCCAM and the National Library of Medicine, offers citations to (and in most cases, abstracts of) articles in scientifically based, peer- reviewed journals on complementary and alternative medicine. It contains 220,000 citations, has links to full text, and allows searchers to limit retrievals by publication type. Look for the Alerts and Advisories, treatment information, resources, links to other organizations (FDA, AHRQ, ODS etc.). American Botanical Council
At the American Botanical Council, we are passionate about helping people live healthier lives through the responsible use of herbs, medicinal plants. We are an independent, nonprofit research and education organization dedicated to providing accurate and reliable information for consumers, healthcare practitioners, researchers, educators, industry and the media.

Herbal Schools

Chestnut Herbs with Juliet Blankespoor
Just as locally grown food is key to long-term sustainability, locally grown medicine is equally as important. That’s why our programs focus on growing your own herbs and all the ways you can enrich your life with edible and medicinal weeds. Preparing herbal medicine is deeply satisfying and empowering, and an essential aspect of all traditional cultures across the globe. Our connection to plants as medicine nourishes this ancient spirit and wakes us up to the profound natural cycles of life. We’re honored to share that connection with you, and we hope it brings you as much joy as it brings us!

Horizon Herbs
We here at Horizon Herbs believe that gardeners can heal the world by growing diversity. It is a well-documented fact that we are living in a time of great loss of species, and it is our understanding that this loss of species is both a cause and an effect of the current ecological downturn. Therefore we propose that everyone engage in species rehabilitation toward a renewed blossoming of diverse gardens on planet earth. It may not be the only answer, but it is one of the best.
