Folk medicine isn't witchcraft. It is a compilation of acquired knowledge that seems to work, most of the time. Like all medicine, it doesn't work 100% of the tie, but it seems to work most of the time.
Like, for instance, willow bark is a great treatment for curing a headache. Chewing a twig with the green bark releases a pain-killer that works like aspirin. In some rural areas of the South, the common willow tree is known as a "headache tree".
Like for instance, crushing an aloe vera leaf releases a gel that is wonderful for light burns, like sunburn.
Like, for instance, the mucus between the stalk and leaf of the common cattail is a powerful numbing agent.
None of these folk remedies are FDA approved. That doesn't make them any less effective. They are simply not approved treatments.
Another common remedy which is in the news is the use of ivermectin as a treatment for Covid-19. It's not FDA approved, but anecdotal evidence seems to indicate that it works. Ivermectin is commonly available from animal supply stores. It's apple-flavored, and the preferred treatment seems to be to smear it on a Chips Ahoy cookie Read the label for dosing information, which is by weight.
Famously, Joe Rogan was recently diagnosed with Covid, and used ivermectin as part of a broad treatment. Of course, the left is going crazy. It's not FDA approved. I know a handful of other people ho have used the same regime as part of their Covid battle. I don't know if it works or not, but you won't be wormy.
The larger idea is that each of us is responsible for our own health care. Hopefully, in consultation with your physician. But, if someone wants to take a worm medicine to treat Covid, it's okay with me. At least they won't be wormy, and there is some evidence to support their decision.
