RUB A535 (also known as Antiphlogistine) is a rubefacient introduced in 1919 and manufactured by Church & Dwight in Montreal, Quebec, Canada.
Patients who are allergic to salicylates (ASA based drugs, such as aspirin), or who are taking anticoagulant medications should avoid the use of the product.
The active ingredients in RUB A535 are camphor, eucalyptus oil, menthol, and methyl salicylate.
[5] Currently, RUB A535 has been released in a variety of products: Historically, the then local distributor was involved in a notable case in the High Court of Australia, about State income tax, Denver Chemical Manufacturing Company v The Commissioner of Taxation (New South Wales) (1949) 79 CLR 296.
It simply involved a difference of views about how to disclose income on a tax return, but is the leading authority in its area.
