Every medical professional who has followed the Journey Together account has nearly all downloaded these herb-picking videos.
There's no other reason; they're just too practical.
The person making the videos personally goes to various mountainous areas to pick herbs, giving viewers an intuitive understanding of the growth habits of medicinal herbs. This kind of hands-on herb-gathering, removed from textbooks, is more three-dimensional and easily accepted.
Beyond the picking, there are various processing techniques for the herbs, and some methods are even more useful than those found in textbooks. These techniques are all practical experiences passed down through generations by the Tang Sect, and to say they're worth their weight in gold is no exaggeration.
