I did that because I wanted to get through the cold season without neck pain or infection. For this I was eating several times a day a teaspoon pure, total of about 4 weeks. Now I eat pretty healthy, although in any case, drink ginger tea (fresh), eat plenty of vegetables and fruits and good oils, but is probably just the whole the sum of its parts. The Manuka helped me - the sore throat had other (which I, of course, where I can, this tip mitgebe here).
Apropos: even the doggy got some of it in his food and it goes in well.
Incidentally, the Manuka does not take itself permanently to you. As a cure, it is enough and the already opened can is preserved for a while.
