I'm a bit of tea and tisane nut and almost always travel with a mini dual voltage kettle so I can start and end my day with a decent cup. The only teas and tisanes I don't like are the overly sugary and artificial blends such as the "bubblegum pineapple poodle carob marshmallow agave summer tea" from places such as Teavana or Davids tea. I am fine however with their regular teas or lightly scented teas.

Sadly one of my favourite Tea blenders, Whittards, went into administration a few years back and the new management have completely changed their historically excellent product into something highly artificial.
