One can consume kava anytime. It is not a fixed constraint that you need to drink it in the morning only. But the fact that needs to be remembered is that your stomach is empty for four to five hours before you are consuming this powerful drink obtained directly from nature. In case you are planning to mix kava powder either with food or alcohol you must stop yourself from doing this. It is so because it not only deteriorates your intestines but also decelerates the functioning of the liver and heart.
