Murphy’s Oil is composed of 98% Naturally Derived Ingredients:
If you’re going through the trouble of extracting the “blood” from the fungi of Yuggoth made from a form of matter that does not naturally occur on Earth and infuse it into a solution that imparts a distinct shine on wood, wouldn’t you play that element up in your packaging?
Probably not, if the shine only lasts until the thinly-spread fungi coalesces into a convoluted ellipsoid creature that will put your brain in a bucket and take it to the stars. I mean, you can’t even admit to that possibility without the FDA coming down on you.
Plus, there are a lot of darkly complected cultists out there who would come to your plants to free the Mi-go amid constant sanity check rolls.
So I guess, ultimately, it is best to leave the consumer wondering what eldritch, fetid matter makes up that 2%.
