Serving size, prep, and portion notes for red rooibos tea
Red rooibos is not tea. It is the oxidised leaf and fine stem of Aspalathus linearis, a fynbos shrub that grows commercially in one corner of South Africa and essentially nowhere else, which is why it is naturally caffeine free rather than decaffeinated: there was never caffeine in it to remove. It is also unusually low in tannins, so it does not turn bitter and astringent if you leave the bag in, and unlike strong black tea it does not meaningfully blunt iron absorption, which is a large part of why South African families give it to children. Where rooibos is not clean is salicylates: it grades high there, the same flag black and green tea carry, so caffeine free does not mean trigger free. On everything else it reads clear, with no histamine, gluten, lactose, sulfite, nickel or glutamate flags, and it is graded strongly anti-inflammatory.
Watch for
High in salicylates, which is the one real caveat. People who move to rooibos to escape caffeine and still get headaches, itching or a stuffy nose are often reacting to the salicylate load rather than missing something else / Naturally caffeine free, not decaffeinated, so there is no residual caffeine to budget for the way there is with decaf coffee or decaf black tea / Graded moderate on FODMAPs, so several strong mugs across a day is a different exposure from one cup, particularly on a strict elimination phase / Oxalate is unrated in our data for rooibos. Its famously low tannin content is often read as a low oxalate claim, but tannins and oxalates are unrelated chemistry, so we make no oxalate claim here / Rooibos lattes, chai-style red blends and flavoured supermarket versions bring their own triggers: milk, added spice, citrus peel, vanilla flavouring and sugar. Grade what is in the bag, not the bush
