Yes, the cure for a worn-down horse is good-old THC.

The article, found buried deep in the coverage of the Grover Cleveland inauguration, talks about how zee Germans and Austrians would need something to get their horses through the high-speed run from Berlin to Vienna -- presumably to refill their beer steins and cheese stashes. They came up with "devices and nostrums" to get the jaded horses and cattle through the drive.
The "orientals" had the best solution, according to one American correspondent. Using their skills with medications, they found that "gunjah" worked best to turn around a jaded horse (much like today with jaded hipsters). And these dudes grew some serious buds, too. Two feet long and three inches wide, according to the report.And these super buds saved the day all the time, apparently. Take this wild tale:
"A very arduous and difficult march was being performed on an unfinished road through a mountainous country. The oxen had a long spell of continuous work and the road was precipitous and foothold was so difficult to get that the cattle became exhausted and totter about helplessly unable to proceed. There could be no halt, for tigers and bears were all around. In this emergency the ever ready and resourcesful drivers, producing their stock of "gunjah" pound up a handful for each bullock, mixed with sugar. The effect was almost instantaneous. The cattle picked up a fresh heart and energy, and trotting on cheerfully soon reached the encampment."They weren't just giving it to the horses and cows, either: "It is used by smokers, who derive intense enjoyment from its narcotic fumes."
Willie would be proud.
