Synthol is a liquid medical product brand available in France since 1920, though the nature of the product has changed through the brand's history.
Synthol was developed by Maurice Bunau-Varilla, a prominent newspaper publisher of the early twentieth century, as a tonic. He promoted it as a cure-all tonic. [1]
The brand was acquired by GlaxoSmithKline. [2] Formerly the formula consisted of chloral hydrate, menthol, veratrol, resorcinol and salicylic acid. Sold mainly as a mouthwash in a distinctive black carton, it is also packaged as a gel and spray for the treatment of muscular pain(s).
Following a rupture in supply 2014–2015 [3] the product returned to French pharmacies in June 2016 with the same composition, minus chloral hydrate, now banned, and with the indication "mouthwash" («bain de bouche») removed. [4]
Among the new uses of the reformulation is endorsement of the Synthol gel as an umbilical cord antiseptic. [5]
A similarly named but unrelated product named SyntholKiné was launched by Glaxo in 2015. [6]
