At present, there is no drink that can replace boiled water.
Admittedly, there is nothing wrong with toxicity without dose. It's really no problem to drink once or twice. However, if you drink it regularly and add the first-pass effect of liver and kidney, some of it will remain in the body, and more and more will continue to be ingested as time and concentration go on.
Eventually it will have a pathogenic effect.
Because water is the source of life, more than 40% of the human body is made of water.
As the substrate of any human reaction, the amount of water can not be ignored.
It is not recommended to substitute other drinks.
