Snake oil used to be really health giving stuff that American Indians would eat for the better of their health, they would leave the snake liver in a bottle to ferment, without any additives, it would be full of bacteria and they would predigest it for us, it would give a high when consumed, made people happy, like raw fermented fish oil gives to some. Unfortunately greedy people appeared and they would start to dilute it, until they would dilute it to 0.1% or even lower and then there was no effect or health giving properties, that is how this all thing came together, and why people use the term -snake oil, because of these salesmen and how they scammed people, but it used to be health food, a good thing. A lot of people don't actually know this.
Just letting you know.
