So I went to the Korean market to get some citron tea-jam. This is stuff that looks like marmalade, except you drop a spoonful of it into a cup of hot water, stir, and whammo, soothing "tea", just what the doctor ordered, so to speak. (The label says "유 자 차", which Text::Unidecode tells me is transliterated as "yu ja ca".)
The Korean lady behind the counter was surprised that a White(tm) person was buying some of this stuff, and asked "You know what this is good for?". I said "Drinking!". But that apparently wasn't a grammatical answer to the question as it started out in Korean in her head. So she ignored it and said "It's good for colds and throat problem!". I said, "That's just what I need". It beats that Thera-flu junk.
