Some science behind the scenes



Theriac and Mithridate are actually general purpose, almost mythical cure-alls that counteract poisons, the plague – you name it – and have been used from ancient  times. 

But the basic ingredients -  opium, hemp [cannabis], myrrh, saffron,  ginger and cinnamon steeped in wine – seem to stay fairly constant, even though we may get the occasional infusion of toe of viper. 

I started to take this seriously when I found that Roman emperor Marcus Aurelius, took it on a regular basis.

Even the toe of viper or at least the venom of some poisonous snakes has now been proved to have medicinal properties, so it appears - given that every other ingredient is medicinally extremely effective against a host of unpleasant pathogens, that whoever invented Theriac knew what they were doing.

Making theriac - Venetian

The mythical side says that you must collect and ferment the herbs and other ingredients for several months. It was supposed to be left to mature for years. 

Theriaca andromachi or Venice Treacle contained 64 ingredients! In addition to viper flesh and opium, it included cinnamon, agarics [fly agaric mushrooms] and gum arabic.

Medicines were at lot more exciting in those days.  They were also probably a lot more effective.
