This ancient recipe was said to be used to keep people healthy during the time of the plague - hence one of its common names - "Four Thieves Tonic." The legend is that a band of thieves used this recipe (or one like it) to avoid the plague when stealing from plague victims - understandably a rather infectious task.
There are many versions of this recipe, which is sometimes called by different names. But I love the name "Fire Cider" - it sounds so warm and invigorating! :-)
The tonic includes a number of health-boosting ingredients traditionally known to fight disease, kill bacteria, and strengthen the immune system. If you cannot find all of these in your area, you may be able to get them online - or omit any that are too difficult to find.
Below are two different versions of this immune-boosting home remedy - pick whichever sounds best to you:
