Tourist trap or ancient remedy?
Snake wine (rượu rắn in Vietnamese) can be found across Vietnam. The snakes, preferably venomous ones, are preserved to have the snake poison dissolved in the liquor. However, because snake venoms are protein-based, they are unfolded and therefore inactivated due to ethanol.
Snakes are widely believed to possess medicinal qualities and the wine is often advertised to cure everything from farsightedness to hair loss, as well as to increase sexual performance.
