Elliman’s Embrocation

James Elliman and his family came to Slough in 1845 and set up a drapery business in Chandos Street which was about where the entrance to the Queensmere multi-storey car park is now. Elliman perfected a formula for an embrocation product that he had been experimenting for several years. It was first sold in 1847 as a treatment for animals but by 1850 it was also being sold for human use to ease aching muscles and joints.


The product was so successful that Elliman closed the drapery business to open a factory to produce the embrocation. Elliman made his sons, James Junior and Samuel, partners and when he died in 1870 they took over the company. Later James Junior took control of the company following Samuel’s death in 1884.

The company continued to grow and by 1911 the embrocation was being sold in 42 countries as two products: ‘Universal Embrocation’ for humans and ‘Royal Embrocation’ for animals, yet there was no difference in the formula.


James Elliman Junior died in 1924 and the company continued to be operated as a family business until 1961, when it was sold to by Horlicks. Horlicks in turn became part of GlaxoSmithKline who continue to produce Elliman’s Embrocation. The advertisement is from 1911.
