For a glass of 200 ml. only 2 grams of tea (about 1 teaspoon) is needed; for a can of 1l. – 1 tablespoon tea.
If you want to prepare the drink properly and it really does show miraculous qualities, never pour the tea with boiling water. The high temperature will destroy the vitamins and worsen the taste of the tea. Allow the boiling water to stand for 5 to 6 minutes to cool down and then pour the tea. And if you want to make the most of its usefulness, forget about sugar and milk.
