dengue prevention - papaya leaves

I have got a forward which says that the papaya leaves work wonders with dengue.

You have to crush them and drink two spoonful of juice a day. it is very bitter and it has to be swollowed. I am not sure about the authenticity and I don't know about side-effects, if any.

But it may be well suggested to someone whose near and dear one is sufferring and there is little hope. I hope it is true and it helps someone.

And everybody please educate all the poor people who you know to keep the cleanliness.
