We are trained with a strong understanding of the pathology and physiology of disease and the human body from a scientific perspective in caring for the whole patient. We are looking at reproducible outcomes with a strong understanding of how and why. If herbalists can do this, they are welcome.
Caution. Proceed with caution as some things may be harmful but there is a benefit to be had in certain scenarios.
