Some history to go with your great find:
The Merchant's Gargling Oil Company of Lockport, New York was founded by Dr. George W. Merchant, a druggist, in 1833, and initially sold to drivers of horses and mules alongside the Erie Canal. Shrewdly marketed with the slogan "Good for Man and Beast," by the end of the 19th century the product was sold worldwide and company was one of Lockport's main industries. Overall, Merchant's Gargling Oil lasted almost 100 years, going out of business in 1928.
