Quote from Joetrader:
Anyone who sells it now is giving you snake oil, whatever the hell that means!
Snake oil originally came from China, where it was used as a remedy for inflammation and pain in rheumatoid arthritis, bursitis, and other similar conditions.
Chinese labourers on railroad gangs involved in building the Transcontinental Railroad to link North America coast to coast gave it to Europeans with joint pain. When rubbed on the skin above the pain, snake oil brought relief, or so it was claimed. This claim was ridiculed by other rival medicine salesmen, especially those selling patent medicines.
In time, snake oil became a generic name for the many medicines that were marketed as a panacea or miraculous remedy, whose ingredients were usually secret, unidentified, or mis-characterized, and mostly inert or ineffective. At best the placebo effect might provide some relief for whatever the problem might have been.
The snake oil peddler became a stereotype in Western movies: a travelling "doctor" with dubious credentials, selling some medicine â such as snake oil â with boisterous marketing hype, often supported by pseudo-scientific evidence. To enhance sales, an accomplice in the crowd would often 'attest' the value of the product in an effort to provoke buying enthusiasm. The "doctor" would prudently leave town before his customers realized that they had been cheated. This practice is also called "grifting" and its practitioners "grifters".
Always be cautious. When you get sucked in by the pitches made by the grifters at the Bright travelling road show, what you may really get is a big expensive bottle of snake oil.
