Zam-Buk

In the early 20th century, it was reported that the formulation comprised 66% paraffin wax, 20% pale resin (colophony), and 14% eucalyptus oil, with small amounts of other ingredients.[2] More recently, the composition eucalyptus oil, 1.8% camphor, 0.5% thyme oil, and 0.65% sassafras oil. The English and Thai varieties do not contain sassafras oil.[6] A 1908 report published in The British Medical Journal estimated that the cost of ingredients for a standard 0.6-ounce (17 g) box was one farthing, yet its retail price was 1s 1½ d.[2]

Widely used in earlier times as an all-round antiseptic and healing ointment, particularly with rugby players worldwide.[7]

When Radio Luxembourg started longwave commercial radio broadcasts in English in 1933, its first advertisers were Fulford's Zam-Buk and Bile Beans.[8]

The Zam-Buk brand and trademark were eventually acquired by Fisons, but production ceased in 1994 after the business was sold to Rhone-Poulenc; the product was revived in the United Kingdom by Rose & Co. in 1996.[9] After the original trademarks expired, Rose & Co successfully resisted a new application by a third party to register Zam-Buk as a trademark in 2008.[10] As of 2015, the trademark for Zam-Buk is registered to Bayer Consumer Care AG in Australia, Canada and the United States.[11][12][13]. Zam Buk is manufactured for Bayer in Thailand by Interthai Pharmaceutical Manufacturing and is distributed in Malaysia, Thailand, Singapore, Indonesia and South Africa.

In Leeds, the tin boxes used for Zam-buk were printed in Hunslet by Charles Lightowler, at their Hunslet Printing Sheds on Jack Lane. They also printed the Peps and Bile Beans tins, which were delivered by horse and cart to the Fulford's factory on Carlton Hill, off Woodhouse Lane.[14]
