What’s the difference between whole herb and standardized extracts?
There is not necessarily any difference between whole herb and standardized extracts. Any extract, including a whole herb or broad spectrum extract, can have constituents quantified and thus be standardized. Some standardized extracts, however, use processes and/or solvents to isolate phytochemicals. In the more extreme cases, these extracts can become so highly concentrated in a single phytochemical or phytochemical group that they exclude the many other constituents that make up the whole herb. Carried too far, these extracts begin to resemble single entity drug isolates rather than broad spectrum herbal extracts.
