Herbalists are some of the original DIYers. They balk at the idea of purchasing from giant pharmaceutical companies what they can make themselves: namely, folk medicine. And they’ve been doing it for centuries.

It’s easy and more common than you think to take herbal medicine. Munching on some parsley after dinner is one way, or sipping on chamomile tea to relieve stress is another. It’s just as easy, if only a little more time-consuming, to follow ancient techniques to create your own potent tinctures that extract and preserve the qualities of many useful plants.
