As a youngster, friends and I used to go swimming after school. There was a temperance bar around the corner from the pool, where the owner used to make his own sarsperilla, dandelion and burdock and cordials, or he’d serve hot vimto, or Bovril. The sarsperilla was delicious - I don’t remember it tasting like TCP?.
I mentioned it to the shopkeeper and he said the taste that makes me think it’s antiseptic is cloves. Maybe it’s something to do with my tastebuds. Red bush tea tastes like tcp to me as well but I got to like the taste of that, too.
