Over the course of the 19th century snake oil transformed from folk remedy, to industrial medicine, to notorious fake.

And yet they can be a great source for Omega-3 fatty acids, most notably the Chinese water snake up to 20% EPA, the Erabu Sea Snake high in DHA. Rattlesnakes are much lower, around 5% to 6% Omega-3's better than nothing. I will always personally prefer Krill Oil for the high absorption.

There will always be scammers and grifters but I would prefer to not let them ruin the original product they are trying to exploit.
