I am working in a Chinese pharmacy & have a product with the English name "Compound Methylsalicylate cataplasma". This is supposed to be a translation from the Chinese "复方水扬酸甲酯巴布膏".
As far as I know, "cataplasma" is not a word in the English language.
Google translate says "巴布膏" means "Babu cream", but that tells me next to nothing, while nciku.com has no results.
