Reliable research is of major importance in determining the herb to use.
Many popular writers claim definitive information without back up data.
They will state such things in their books as “that is not true” without proofing the pudding.
Ask for proof/research for data/source out information on the active ingredients in herbs and how they work in the body.
These days there is a lot of reliable information available for free by reliable institutions in addition to the older texts by John Lust, Maude Grieve, Edgar Cayce.
You can find data / research and studies that have been done on all these sites.
The Sloan-Kettering Cancer Centre and the Mayo Clinic are two good sources for herbal information.
