The discovery of the month for me is the bilberry leaf tea, which has a so delicious flavor that rivals the fruit teas. The tea can be prepared both from bilberry (Vaccinium myrtillus L.) and cranberry (Vaccinium vitis-idaea L.) leaves. The only "problem" with them is that they are endangered or protected in Hungary, but they are frequent and harvestable in Transylvania, Harghita area. The leaves contain mainly tannins and flavones.
