the tea leaves have a lower boiling point and thus reduce the boiling point of the water (in the mixture)

The water can sometimes become superheated if heated to long. This is caused by a lack of bubbles forming. Once something is inserted in the cup and the liquid is disturbed, the pressure is relieved and bubbles form and the water appears to boil. A good way to avoid this is to add something in the water like a wooden stick will help allow enough bubbles to form and keep the water from superheating. Another way is to not heat the water for such a long time in the microwave.
Oh yeah and dissolving any salt or any other substance to water will not decrease the bp, it will increase the according to the amount of solute you add. Some of the previous answers state otherwise.

maybe you have it backwards, i've never seen that happen to me
one needs to heat up the water just before the rolling boil point. then add the tea leaves and you can steep it according toyr taste. just dont forget to remove the tea leaves after a short while or the tea will taste bitter.
i dont know why you get boiling water when you add tea leaves.
however it sounds like it is as when one makes coffee on a pot, as soon as the coffee is added it boils over with hot water bubbles.
its probably the chemicals released into the water by the leaf itself or coffee for example. once mixed into hot water there is a brief bubble boiling over from the water.

It is practically impossible to superheat water using a gas or electric heater (As opposed to a microwave oven, for example).
The bubbles will form or won't form according to the amount of nucleation centers in the the water or on the cup surfaces. When you add tea leaves, which have a large and rugged surface area you increase the amount of bubble nucleation centers and allow them to form.

the water is already heated, but the cup is so perfect that once you add another compound it creates a geyser. my advise is to score that mug before you hurt yourself. you superheated the water. it's easy to do with new stuff (and old) and it can be really really dangerous
