>BS (and the lack of any evidence to prove it helps confirms that)
back in USSR it was practiced as a home remedy in case of flu and i had it several times as child. You do feel warmed up similar like if you had a strong massage done upon your back and you nicely drift asleep after that. It is in general direction of supportive actions during flu. It isn't a cure - and there is no cure for [viral] flu - yet it helps getting through it. The same way like a bit of vodka with really hot tea following a really heavy sauna session - the way i been managing flu since high school - there is no medical evidence that it medically helps too, yet it does help you to get through :)
