The moment an ill can be patiently handled, it is disarmed of its poison, though not of its pain.
– Henry Ward Beecher
All men possess in their bodies a poison which acts upon serpents; and the human saliva, it is said, makes them take to flight, as though they had been touched with boiling water. The same substance, it is said, destroys them the moment it enters their throat.
– Pliny the Elder
