Blueberry leaf tea

I didnt realise you could use bluebery leaves in this way? I have two blueberry bushes in the garden but very rarely get a blueberry from them as the birds get most of them. I grow them  as an ornamental shrub mainly for their autumn foliage. They have a sentimental value as well because I got them off my neighbour who has now unfortunately passed away.
I may try utilising some of the leaves for tea as they supposedly have health benefits?
