Considering the amount of caffeine the body gets through the consumption of tea (50 mg per
time), miang consumption should not exceed 35 g (dry leaf) per time and should not be over
140 g per day. However, although tea products have been restricted to not exceed 50 mg per
time, miang is different in that it is consumed as a form of wet solid (whole leaf) which
contains more concentrated substances including the caffeine. Furthermore, a normal amount of
miang must contain more substances than a cup of tea (a cup of tea is made from 1 teaspoon of
tea leaf), so this cannot be used as standard for miang because the caffeine contents will surely
be over the suggested limited amount for all samples. This is main reason why miang product
standards should be established on the basis of adequate research data.
