In addition to previous (and excellent) replies, language can be taken in different contexts. For example, the portion of the statement, "traditional natural herb wine", what does the author mean using the word TRADITIONAL, and is that the same meaning as yours? I made a traditional mead a while back. I hated the stuff and dumped it. I then made a honey wine with the latest technology (GoFerm, Fermaid, wine yeast, etc.). I loved the batch.
I suggest using caution on meanings of authors of books. They did their job...put something in print, and sold the book to you
. I screwed up more batches than I care to admit following recipes of various authors. I've said this often on different forums, >>recipes don't tell you everything<<.
The second part, "using blends of pure juices, honey, fresh or dried fruits as replacements as they would complement the principal herb ingredient", will depend on how you want the finished product to taste. For example, wine made from pears has an extremely delicate flavor. Adding anything to a pure pear wine will deviate from that flavor, in this case loosely referring to the term "principle herb". Simply changing methods of fermenting and slight changes of yeasts can make a totally different PEAR wine. Using white sugar (cane or beet), raw sugar, or even corn sugar (dextrose) will change the final flavor of a pear wine.
In my opinion, the ultimate challenge of a home wine maker is to have a final product/taste in mind and use the raw ingredients and methods to hit that target.
Kudos for asking advice and best of luck!
