Tea before bed
A timing question rather than an ingredient one: what is drinkable in the last hour of the evening, and which of the teas with a low-caffeine reputation actually are made from the tea plant. It answers the composition question and declines the physiology one.
What this page answers, and what it does not
This page answers a question about composition — which of these drinks are made from the tea plant, and what that means for what is in them. It declines the question underneath it, which is what caffeine at that hour does to a particular person. TeaHQ’s written assessment of that question is held pending human review, and a compositional fact is not a substitute for it.
TeaHQ's assessment is written and held pending human review. Every plant listed below is listed with the reason it is associated with this search. None of those reasons is a finding about what it does.
What people mean by this
Almost everyone typing this already has a drink in mind and wants permission for it, or wants a substitute for it. The real content of the query is compositional and it splits cleanly: is this thing made from Camellia sinensis or not, and if it is, does anything about how it was processed change what is in it. That second half is where the folk knowledge is worst. Roasting, stem content and later harvesting all have reputations for producing a low-caffeine cup, and those reputations are repeated far more confidently than the underlying variation justifies. A second, much smaller group means something else entirely — they want to know what the last drink of the day is in other people’s households, which is a question about custom and has answers as specific as a Korean jug of roasted-corn infusion or a French café order of verveine. TeaHQ can answer both of those. It cannot answer the third question hiding behind them.
What appears under this search, and why
Traditional practice
A named tradition uses it this way. That is a record of what people do, not evidence that it has an effect.
Ordered as verveine in French cafés, where it and tilleul are the two tisanes everyone knows by name. In Peru and Ecuador the same plant is hierba luisa, grown in kitchen gardens; in Morocco it is louisa and goes into mint tea alongside the mint.
Recorded by: French café ordering convention since the nineteenth century, and Peruvian, Ecuadorian and Moroccan domestic practice
The default late drink across a very wide band of Europe, North Africa and the Middle East, and the one plant most people can name without being prompted when asked what is drunk last.
Recorded by: European, Egyptian and Iranian household practice, in each case as an ordinary domestic drink rather than a speciality one
Everyday habit
An everyday habit rather than a formal tradition. Recorded because it explains why the association exists.
Kept in a jug in the refrigerator through the Japanese summer and served to everyone in the household including small children, precisely because it contains no caffeine. Korean households do the same with boricha, often in place of water at the table.
Served in Korean homes and restaurants in place of water, hot in winter and cold in summer, with corn silk often included for its sweetness. Gangwon province is its heartland and it follows the older barley pattern rather than any Mesoamerican one.
What is in the leaf
A fact about what the leaf contains. It describes the tea, and makes no statement about any person drinking it.
Roasted in a pan or drum until the leaf turns reddish-brown, but the underlying material is ordinary bancha or stem tea and it is still Camellia sinensis. The roast changes the flavour completely and does not change what plant it came from.
Made from the stems and leaf ribs sorted out of sencha and gyokuro production. Stem material carries less of the compounds that make leaf astringent, which is a fact about flavour and not a licence to assume anything else about it.
A South African legume-family shrub, not a tea plant, with no caffeine in it. It takes milk and sugar in South African households in a way that mirrors British tea habits, which is why it substitutes so easily for a late cup.
The softer of the two South African infusions and still substantially wild-gathered, which is unusual for a commercial botanical. Like rooibos it is not Camellia sinensis and contains no caffeine.
How the market serves this search
The market answers this query in two directions at once. One is the herbal shelf, which sells the absence of caffeine as a property of the whole category and is broadly right about it. The other is the decaffeinated-tea shelf, which sells a processed Camellia sinensis and is much smaller than the demand would predict — decaffeination costs flavour, and a shopper who will accept a rooibos does not need it. The gap between the two is where the low-caffeine reputations live: white tea, roasted tea and stem tea are all sold, at least by implication, as a middle option, and the packaging rarely states what the claim rests on.
Description of a market, not endorsement of it. TeaHQ sells nothing and links to no seller.
Caffeine, as a fact about the leaf
The dividing line is the plant, not the processing. Camellia sinensis contains caffeine in every category made from it — white, green, yellow, oolong, black and dark — while rooibos, honeybush, roasted barley and roasted corn contain none because they are different species entirely. Within the tea plant, leaf weight and steeping time move the quantity in a cup more than the category name does.

The traditions behind these plants
Each line above says in a sentence why a plant appears under this search. These records say who practises the tradition, where, in what period, in what preparation, and what that tradition itself states the practice is for — one tradition at a time, because they frequently disagree with each other.

Evening and rest
The end of the day, and the largest commercial category in the whole subject. Most of these queries are really two questions wearing one phrase — what people drink at ten at night, and whether it does anything.
