Cinnamon is one of the all time great "go to" spices when it comes to old herbal remedies, however it is rarely used alone. Most often, cinnamon is used as an added ingredient to herbal teas or other preparations. Because of that, most of the entries here are recipes with many other ingredients. It is likely that the addition of cinnamon is often for flavor, however it does have a warming effect on the body and may add punch to the prescription.
Some of these remedies are benign and might actually work, for example: cinnamon tea for a cold and the lovely tea for indigestion. Others might be downright dangerous - check out the cures for Blindness and Syphilis. As always, if you decide to try one or more of the following remedies, please use common sense and educate yourself beforehand. Remember, these cures are old and were used in an era of ignorance and superstition....

As you explore this site, you may find links to a "page not found" instead of something cool and magickal. For this I apologize. I am very working hard behind the scenes to restore those pages along with a link to their homes on my new website where they can be viewed in full.
