The leaves are not that tasty mate believe! you leave a lump of them to congeal in the side of your mouth with some sodium bicarb and after about 10 mins or so they give you a bit of a lift. Good for altitude sickness (fuck knows why) and great for trekking, had me powering up mountains in Peru! Coca tea made from the leaves is lovely though, great way to start the day, better than Tetley
