No hard evidence behind MediWise pain relieving patch

I saw a Facebook ad for the "The OSMO Patch™ which provides Fast & Effective relief from swelling, pain and inflammation from bursitis" (bursitis is inflammation of the fluid-filled sac [bursa] that lies between a tendon and skin, or between a tendon and bone). I asked the manufacturer, MediWise Pty Ltd, to provide harder evidence than letters of testimonials found on their website.  I also asked whether their data has been published in peer-reviewed scientific journals.

MediWise customer care admitted that there is no hard clinical evidence to support their claims because they ‘do not have the kind funds to commission such research' and pointed me to a YouTube video, which explains how the patch works. Apparently it involves the mineral tourmaline which is described as an infra-red emitter. Increased sweating induced by infra-red emissions from the patch increases the osmotic pressure in the surrounding tissues, loss of fluid from the blood vessels to compensate, and loss of fluid from the adjacent inflammation. However, this all falls down because blood circulates, so local dehydration of blood vessels will not occur.
