Drinks from Indonesia are very easy to do. And to think I drink an alternative herbal medicine for many years without knowing it by browsing the books I saw that this recipe is also called. To keep you just warm water or boiled and cooled water, half lemon juice and ginger. I prefer the latter but possibly too subtle fireplace also use powdered ginger. Lemon is a celebrity who needs no introduction; many people use it every day. Take this mixture on an empty stomach if possible.
