In China, the "glorious" tradition was not less known than in other countries. Before serving the emperor of any foods it previously tried eunuch. In addition, on each dish and each bowl lay a silver plate, with which checks to see if the food and drink poisoned. But if we talk about the heyday of this art, it is necessary to appeal to Rome. Custom poison emperors so entered into the practice that for each of them there was a specific position - otvedyvatelya dishes. He had to try every dish, applied to the Emperor, to see if it would poison his death to warn of the danger. However, this measure has led only to the fact that instead of instant poisons began to use poisons, acting slowly. Another philosopher Theophrastus wrote about the poisons that kill is a man of only after a certain time - a month, a year, or even three years. "It's easier all - he wrote - are dying, those who die quickly. There is no antidote "to the poison. The mention of the slow poisons that cause cough, fever or coughing up blood, and can be found in Plutarch. He informs the other poison, which gradually led to a significant reduction in mental capacity.
