The tea temperatures are all wrong, they should be:

Black tea - 95 C

Oolong Tea - 80-90 C (depending on oxidation level, more = higher temperature)

Green Tea - 75 C

Yellow Tea - 70-75 C

White Tea - 70 C

Using boiling water will scald the leaves and leave a bitter taste.

All teas are herbal.

I'm not (just) being facetious - I don't think it can be well answered, because you're obviously thinking of something specific, and someone's going to answer with their own probably different specific 'herbal' tea in mind.

Around 70-80 C, you'll have to play around with it as it's a little different for each tisane.

Fun fact, tea is technically only the leaves of the camellia sinensis plant, all the permutations of black, green, white etc teas are how the leaves are processed by humans after cultivation, they're not different species of the plant. Any "teas" that are not of the camellia sinensis plant are technically called tisanes, although in colloquial usage no one says tisane.

What’s the purpose of this test? Why would they use boiling water for green tea?

I've read in one of previous threads about it that it's for the purpose of comparing different teas accurately. It's not supposed to result in the best possible tea. Instead it's supposed to make the tea's aroma and taste as clear as possible and it's supposed to be used uniformly across different varieties of tea, so that they can be compared accurately without much error margin introduced by the preparation itself.…

It's just odd that one would not make green tea at anywhere near the right temperature. Green tea is simply not comparable with black; they are fundamentally different. It is as if there were an ISO standard on the quality of fruits and they are "compared" by assessing color (deviation from yellow is a fault, increasing by reflected wavelength difference).

I prepare my herbal teas in a microwave oven.

As an example, I use a glass teapot with 1 liter of water. I preheat the water 4 minutes (@ 1000 W), I add the tea bags, then I heat again for 2 minutes 10 seconds.

Obviously the precise times will be different for other microwave ovens and teapots, but the point is that with a microwave oven you can experiment with fine adjustments of the time until you get what you deem to be the best taste.

Once optimal times are found, the process will be perfectly reproducible, so you will obtain the best taste every time.

I have transitioned a couple of years ago from making the tea on a traditional gas stove to using the microwave oven and the result was much better tea tastes that are always the same.

Controlling the time in this case controls the temperature, but it is more convenient than attempting to control directly the temperature when using other cooking devices.
