This page explains the tea tin we write about and the headlines we would run next to it. The tin is Get Smart, an herb tea for memory and focus from The Republic of Tea. It is a food, a caffeine-free rooibos blend sold in tea bags, not a supplement. Nothing here is medical advice.
You likely arrived from a paid placement. The headline was written to stop a scroll. Some headlines lean on a story. The tin facts below are the part we can point at.
This site is a paid advertisement. If you buy through a link, we may be paid a commission.
The tin holds 36 tea bags at $13.75 on the seller's page as read November 9, 2026. A refill of 36 bags is $13.25 on the same page. The seller prints the herbs on the panel and prints no milligrams per bag. No study has tested this blend. The seller's own line about memory ends in an asterisk, and we do not repeat it as a promise.
| The headline as you saw it | What is actually behind it |
|---|---|
| Tea Buyer: 5 Reasons the Second Cup Costs More Than the Tin | Partly true The caffeine span for brewed coffee comes from the FDA, and the single-dose and daily lines come from the European food-safety panel. "Costs more than the tin" is our frame and our arithmetic, not a trial result against this tea. |
| Caffeine-free, 36 bags, $13.75 | Broadly supported Printed on the seller's product page on November 9, 2026. The refill is $13.25. We do not print a per-serving milligram figure because the seller does not print one. |
| Ginkgo improves memory | Our headline was wrong We do not run that line. A 2011 trial used 120 milligrams a day of a standardized extract for 12 weeks in adults 60 and older, was paid for by an extract maker, and called its gains modest. The largest trial, 3,069 adults, found no difference from placebo. This bag does not print a milligram of ginkgo. |
| 30-day money-back | Withdrawn We did not find a refund window on the product page we opened. We will not print a seal the seller did not print. |
The product page we opened on November 9, 2026 did not print a day-count refund window. The company's policies pages may hold one, and their answer outranks our miss. Ask them before you buy if the window matters to you. The address printed on the seller's site is 1 Twin Dolphin Dr, Redwood City, CA 94065. Phone 800-298-4832. Email [email protected].
Organic rooibos is the first ingredient and the body of the cup. Eleuthero root is second, gotu kola leaf is fourth, rosemary leaf is fifth, and ginkgo leaf is seventh on a list of ten. Gotu kola and rosemary each have one small trial behind them, at weighed doses that this bag does not print. Ginkgo has large trials behind the standardized extract, and the biggest of them was null. Eleuthero, cranberry, hibiscus, orange peel, rosehips and chicory are on the label with no amounts, and we do not assign them a result.
The seller's list, with no milligrams added by us.
The red bush of South Africa, whose needle-like leaves are cut, bruised and oxidized to a brick red before drying. It is a food drink, naturally caffeine-free, a little sweet on its own, and it carries the color of this cup.
Traditional and everyday use. Drunk hot and iced in South Africa for generations and sold in the United States as a caffeine-free evening tea.
What the research says. No trial of rooibos on memory or attention in healthy older adults is on file. Descriptive only.
Amount per serving in Get Smart. not stated (listed first; milligrams per bag not printed)
Good to know. Generally regarded as safe as a food. If you take anything daily, show the tin to your pharmacist before your first cup.
A spiny shrub of Siberia and northern Asia, once sold as "Siberian ginseng" though it is no relation of ginseng at all. The dried root has been part of Russian and Chinese herbal practice for well over a century, and it was the plant behind the old Soviet "adaptogen" research of the 1960s.
Traditional and everyday use. A root of the old kitchen-shelf tradition, taken as tea or extract in Siberia, northeastern China and Korea for generations.
What the research says. The National Institutes of Health states there is not enough evidence to know whether eleuthero helps with any health condition.[7] No trial has tested this tin.
Amount per serving in Get Smart. not stated (listed second on the panel)
Good to know. May affect blood pressure in some people and may add to the effect of anything that thins the blood. Talk to your doctor before use if you take anything daily or have high blood pressure.
A small creeping plant of wet ground across South and Southeast Asia, with round, scalloped leaves eaten as a salad green in Sri Lanka and Vietnam. The leaf is also dried for tea and sold as an extract.
Traditional and everyday use. A leaf of Ayurvedic and Southeast Asian kitchen tradition, eaten fresh, pressed into juice, or steeped.
What the research says. In a small 2-month placebo-controlled trial of 28 healthy older adults, the highest dose, 750 milligrams a day of a gotu kola extract, was associated with improved working-memory performance and higher self-rated alertness.[5] Only the high dose moved, and the groups were seven people each. A 2017 review that pooled the randomized trials found no significant effect on cognitive test scores overall, though it did find higher self-rated alertness.[6]
Amount per serving in Get Smart. not stated (listed fourth on the panel; a tea bag with gotu kola fourth on a ten-item list is not a weighed 750-milligram extract)
Good to know. Skin rash has been reported. Rare reports of harm to the organ that processes what you swallow have been linked to gotu kola products: stop and talk to your doctor if you notice unusual tiredness, dark urine, or yellowing of the skin or eyes. Talk to your doctor before use if you take anything daily.
A small evergreen shrub of the mint family, native to the dry, rocky Mediterranean coast, whose needle-like leaves are one of the world's most familiar cooking herbs. The FDA lists rosemary among spices generally recognized as safe for their intended use in food.
Traditional and everyday use. In ancient Greece and Rome rosemary was associated with memory, and in folklore it has long been an emblem of remembrance. In the kitchen it flavors roasts, breads and oils.
What the research says. In a small crossover trial of 28 adults with an average age of 75, a single 750-milligram dose of dried rosemary leaf, close to a culinary amount, was associated with faster speed of memory compared with placebo, while a much larger dose, 6,000 milligrams, had the opposite effect.[4] More was not better, and the effect was measured once, hours after one dose.
Amount per serving in Get Smart. not stated (listed fifth on the panel; the seller does not print how much of the bag is rosemary)
Good to know. A familiar food herb at culinary amounts. The trial's high dose was the one that went the wrong way.
Pieces of the fan-shaped leaf of the ginkgo tree, a species so ancient it is called a living fossil, planted along city streets across the world. Here it is the dried leaf in a tea blend, a different thing from the standardized leaf extract sold in capsules.
Traditional and everyday use. Ginkgo leaf extract has been sold as a "memory herb" for decades; the dried leaf is also brewed as a tea.
What the research says. In a 12-week placebo-controlled trial, 120 milligrams a day of a standardized extract in adults aged 60 and older was associated with modest improvements on a computerized attention and memory battery; the trial was financed by a maker of ginkgo extract.[1] In the largest trial to date, 3,069 adults aged 72 to 96 took 120 milligrams of a standardized extract twice a day for a median of 6.1 years and declined at the same rate as the placebo group in memory, attention, language and every other domain measured.[2] The National Institutes of Health states there is no conclusive evidence that ginkgo is helpful for any health condition.[3] A pinch of dried leaf seventh on a tea-bag list is far less than the extract doses in either trial.
Amount per serving in Get Smart. not stated (listed seventh on the panel)
Good to know. Ginkgo may increase the risk of bleeding in people who take anything that thins the blood; fresh ginkgo seeds are toxic. Talk to your doctor before use if you take anything daily or are due for an operation.
The seller lists these five as flavor and body for the cup. Cranberry and hibiscus push the red of the rooibos redder and add tartness; orange peel and rosehips add a citrus note; chicory root adds a roasted edge. No amounts are printed for any of them, and we assign them no result.
Good to know. Hibiscus is tart and acidic. People who are pregnant or nursing, or who take anything daily, should show the tin to a pharmacist before the first cup.

No. The 2011 trial was a weighed standardized extract, 120 milligrams a day for 12 weeks, in a group of adults 60 and older, paid for by an extract maker. The largest ginkgo trial was null. This bag prints no milligrams.
The seller prints it as caffeine-free. Rooibos is naturally caffeine-free, and none of the ten listed ingredients is a caffeine plant.
The tin is $13.75 for 36 bags on the seller's page as read November 9, 2026. Divide one by the other and you get about 38 cents a bag. The refill is $13.25 for the same count.
