Gingering

[1] Historically, the process, the purpose of which was often to make an older horse behave like one that was younger or to liven up a sick or weakened animal temporarily, was known as feaguing (from which the modern term figging derives), and involved a piece of ginger, onion, pepper or tobacco.

[2][3][4][5][6] Francis Grose added in his Classical Dictionary of the Vulgar Tongue (1796) "and formerly, as it is said, a live eel",[7] but that is very unlikely.

The modern practice commonly involves a paste product with concentrated gingerol.

[8] For the halter horses in the Arabian and American Saddlebred breeds, high tail carriage and animation are desired traits.

A modern veterinary dictionary notes that vaginal placement is more effective than anal insertion because the irritant is likely to remain in place longer.
