I’m from Croatia, a Slavic country and tea drinkingi s the way you described: frome the camelia sinensis family it (was) exclusively black or ‘russian’ tea with honey/sugar and lemon. Tisanes like chamomile, mint, hibiscus, nettle, thyme, etc are considered proper tea here. Each is knows to have medicinal value and people start drinking them as babies.
In coffee houses they normally serve tea with lemon and sugar, you have to request honey.
