Theriac potions, also known as Theriacum, were a popular medical treatment in ancient times and the Middle Ages. The potion was a complex mixture of various herbs, spices, and other ingredients, including snake venom, opium, and myrrh. The concoction was believed to have powerful healing properties and was used to treat a wide range of illnesses, including the bubonic plague. The use of Theriac potions was not limited to Europe but was also widespread in the Middle East and Asia. However, the production and use of Theriac potions were expensive and often reserved for the wealthy.
