The extensively revised and updated 5th edition of the Phytotherapy Desk Reference has been published

This book has been designed as a reliable desk reference for the busy herbalist/phytotherapist. It contains short, precise descriptions of over 236 of most commonly used herbs.

The intention is to provide practitioners with a limited number of reliable therapeutic actions with some reliable indications for each herb and with the information organised in such a way as to be a valuable clinical tool.

The short monographs also provide the main active constituents, the qualities of the herbs, known drug interactions and any caution or contraindications as well as the recommended dosage for liquid extracts.

As a quick reference index, the herbs have been grouped together under their therapeutic actions and indications. These lists are of course not exhaustive and may be expanded with time. They do, however, include the actions and indications on which most authors seem to agree on. Information about the herbs has come from accepted textbooks (see bibliography) and other published material.

Phytotherapy Desk Reference 5th Edition ISBN: 978-0-646-82443-7 Soft-cover, spiral bound. 200 pages. 233 Monographs.

I firmly believe in the value and preservation of traditional medicine. I work to inform health professionals about the incredible value of medicinal plants and I work with industry to improve the quality of the medicinal products made from medicinal plants and nutrients.

I now divide my time between clinical practice where I specialise in cancer support and my various business activities.

Michael Thomsen is a Naturopath with over 30 years’ experience. Originally from Denmark, Michael completed studies in Naturopathy and Herbal Medicine in Sydney, graduating in 1986.
