Place on seredníj Vogon, cover and wait to boil. I cookware with double bottom so I immediately turn off. The lid will not open, until cool. Bring to a boil in ordinary dishes, literally, minute, also do not open the lid until it has cooled down. Strain, if you believe, which turned out to be very concentrated, can be diluted with boiled water. We have this drink brewed for the Holy Supper, but you can cook it on any other day. Very tasty and healthy drink. Removes toxins from the body, cleans, useful for children. You can also add dried apricots, prunes, raisins, fig, Dried cherries ... I wish you all good health!!!
