Herbal Actions
with David Hoffmann

David Hoffmann gives an assessment of the value (or lack of) of science for understanding herbs and making clinical judgements. David talks about primary and secondary constituents, types of chemical constituents (terpenes, alkaloids,etc.), how science can’t account for whole plant effects, standardization and the link between chemistry and herbal actions.

In this clip, David talks about the herb fennel and the incorrect assumption by some scientists that it is toxic. Listen in:

In this clip David discusses the herbal action of anti-cattarhal herbs such as goldenseal, goldenrod and elderflower. Listen in:



"Phytotherapy is a thriving medical modality that uses whole plants to treat whole people, facilitating the healing process within the framework of holistic medicine. It is both an art and a science. With its roots in the past, it is still relevant and meaningful in the present, offering great potential contributions to modern medicine.

Herbalism has a scope of uses as wide as any form of medicine, as herbs may be used for any condition that is medically treatable. This statement is not meant to imply that herbs are a panacea for the ills of humanity! However, the ecological integration of plant activity with human physiology offers the potential for facilitating the healing process at any time in any situation"

David Hoffman from "Medical Herbalism"
