Adaptogenic Teas: What They Are and Which Ones Work
The word “adaptogen” gets thrown around a lot in wellness circles, usually next to a $14 latte or a supplement with twenty ingredients. But the concept behind adaptogens is real, and some of the research is genuinely interesting — even if it doesn’t always live up to the marketing.
Adaptogens are plants and fungi that appear to help your body regulate its stress response. The idea isn’t that they eliminate stress. It’s that they help your system recover from it more efficiently, keeping you closer to baseline rather than stuck in overdrive.
What Adaptogens Actually Do in Your Body
Your stress response runs through the hypothalamic-pituitary-adrenal axis — the HPA axis. When you’re under chronic stress, this system can get dysregulated. Cortisol stays elevated when it shouldn’t be, sleep suffers, inflammation creeps up, and your immune function takes a hit.
A 2010 review published in Pharmaceuticals (Panossian and Wikman) examined the pharmacology of adaptogens and found that these compounds appear to modulate several key mediators of the stress response, including cortisol, nitric oxide, and molecular chaperones like Hsp70. The proposed mechanism is that adaptogens don’t just sedate you or amp you up — they nudge your stress-response system toward balance.
That’s the theory, anyway. The quality of evidence varies wildly from one adaptogen to the next. Some have decent clinical trials behind them. Others are mostly backed by centuries of traditional use and a handful of animal studies. I’ll be upfront about which is which.
Ashwagandha Tea
What the Research Says
Ashwagandha (Withania somnifera) is probably the most studied adaptogen. A 2012 randomized controlled trial published in the Indian Journal of Psychological Medicine found that participants taking 300 mg of ashwagandha root extract twice daily had significantly lower serum cortisol levels compared to placebo — a 28% reduction over 60 days. They also reported substantially lower scores on perceived stress scales.
A 2019 systematic review in the Journal of Alternative and Complementary Medicine looked at five randomized trials and concluded that ashwagandha significantly improved stress and anxiety outcomes compared to placebo. The effect sizes were moderate but consistent.
The caveat: most studies use concentrated root extract, not tea. Brewing the root as a tea delivers lower doses of the active withanolides, so the effects may be milder than what clinical trials demonstrate.
How to Brew It
Ashwagandha root has an earthy, slightly bitter taste — “ashwagandha” literally translates to “smell of horse.” Use about one teaspoon of dried root per cup. Simmer (don’t just steep) in water for 10-15 minutes. Many people add honey, cinnamon, or warm milk to make it more palatable. Drinking it in the evening makes sense given its calming properties.
Tulsi (Holy Basil) Tea
What the Research Says
Tulsi (Ocimum tenuiflorum) has been central to Ayurvedic medicine for thousands of years. The research base is growing and generally positive. A 2014 review in the Journal of Ayurveda and Integrative Medicine examined 24 studies and found evidence supporting tulsi’s anxiolytic, antidepressant, and neuroprotective properties.
A randomized controlled trial published in Evidence-Based Complementary and Alternative Medicine (2012) found that participants taking 1,200 mg of tulsi daily reported 39% greater improvement in general stress symptoms compared to placebo. Tulsi appears to modulate cortisol and also has measurable anti-inflammatory effects, which matters because chronic stress and chronic inflammation tend to feed each other.
If you’re already exploring chamomile tea for anxiety, tulsi is worth having in your rotation. They work through different mechanisms, and some people respond better to one than the other.
How to Brew It
Tulsi is one of the most pleasant-tasting adaptogens — slightly peppery with clove-like notes and a mild sweetness. Use 1-2 teaspoons of dried tulsi leaves per cup, steep in just-boiled water for 5-7 minutes. It’s good on its own and doesn’t need much dressing up. Three cups daily is the traditional recommendation and roughly aligns with the doses used in studies.
Rhodiola Rosea Tea
What the Research Says
Rhodiola is best known for combating fatigue rather than calming you down. A 2012 review in BMC Complementary and Alternative Medicine examined 11 placebo-controlled trials and found evidence that rhodiola can improve physical and mental fatigue during periods of stress. A notable 2009 study in Planta Medica found that rhodiola extract significantly reduced fatigue and improved attention in physicians working night shifts.
The evidence for rhodiola is moderate — better than most adaptogens, though still mostly based on small trials. It appears to influence serotonin and dopamine activity, which could explain both the anti-fatigue and mild mood-lifting effects people report.
How to Brew It
Rhodiola root is tough and woody. You need to simmer it, not just steep it. Use one teaspoon of dried, chopped root per cup and let it simmer for 15-20 minutes. The taste is mildly bitter with a faint rose-like quality. Morning or early afternoon is the best time — rhodiola can be mildly stimulating, and drinking it late may interfere with sleep. If you’re sensitive to stimulants, start with a half-strength cup.
Reishi Mushroom Tea
What the Research Says
Reishi (Ganoderma lucidum) sits at the intersection of stress support and immune modulation. A 2012 study in the Journal of Ethnopharmacology examined reishi’s effects on neurasthenia (chronic fatigue with irritability) and found significant improvements in fatigue and well-being after 8 weeks compared to placebo.
The immune-modulating effects have stronger evidence. Reishi contains beta-glucans and triterpenoids that appear to regulate immune cell activity. If your interest in immune support extends beyond stress, it’s worth reading about other teas that support immune function as well.
I should be honest: the stress-specific evidence for reishi is thinner than for ashwagandha or rhodiola. Much of reishi’s reputation rests on traditional Chinese medicine and animal studies. The human trials that exist are promising but few.
How to Brew It
Reishi is woody and hard — you’re essentially making a decoction, not a tea. Slice or break dried reishi into small pieces, use about 3-5 grams per two cups of water, and simmer for at least 30 minutes. Some people go as long as two hours. The result is bitter and earthy. Honey helps. You can also buy pre-sliced or powdered reishi, which is more convenient and extracts more efficiently.
Licorice Root Tea
What the Research Says
Licorice root (Glycyrrhiza glabra) supports your adrenal system in a specific way: it contains glycyrrhizin, which inhibits the enzyme that breaks down cortisol. This effectively extends cortisol’s active life in your body. For people with adrenal fatigue — those who feel chronically depleted rather than chronically wired — this can be helpful.
A study in Molecular and Cellular Endocrinology confirmed that glycyrrhizin inhibits 11β-hydroxysteroid dehydrogenase, the enzyme responsible for cortisol metabolism. The practical effect is that your existing cortisol works longer and harder.
Here’s the important warning: because licorice preserves cortisol, it can raise blood pressure. This isn’t a theoretical concern — it’s well-documented. If you have hypertension or take blood pressure medication, avoid licorice root tea or use deglycyrrhizinated (DGL) versions, which have the glycyrrhizin removed. Even for healthy adults, limit consumption to 1-2 cups daily and take breaks.
Licorice root also has notable anti-inflammatory properties, which adds to its usefulness for stress-related inflammation.
How to Brew It
Licorice root is naturally sweet — significantly sweeter than sugar, in fact. Use one teaspoon of dried root per cup and steep for 5-10 minutes. It blends well with other herbs, which is why you’ll find it in many commercial tea blends. Pair it with peppermint or ginger for a more complex flavor. Just keep track of your total intake across all sources.
Putting It Into Practice
If you’re new to adaptogenic teas, don’t buy six different roots and start drinking all of them. Pick one based on your primary concern:
Chronic stress and anxiety: Start with ashwagandha or tulsi. Tulsi is gentler and more pleasant to drink. Ashwagandha has more clinical evidence but tastes worse.
Fatigue and burnout: Rhodiola in the morning is your best bet. Pair it with calming teas like chamomile at night if stress is also disrupting your sleep.
Immune support plus stress: Reishi, recognizing that the stress evidence is less robust than the immune evidence.
Adrenal depletion: Licorice root, with careful attention to blood pressure.
Give any adaptogen at least 4-6 weeks of consistent daily use before judging whether it’s working. These aren’t caffeine — you won’t feel an immediate effect. The changes are gradual and cumulative.
It’s also worth noting that adaptogens work better alongside the basics. No amount of ashwagandha will compensate for six hours of sleep, chronic dehydration, or zero physical activity. Think of these teas as one tool in a broader approach to managing stress, not a standalone solution.
For caffeine-free options that support relaxation through different mechanisms, rooibos tea is another solid choice — it’s rich in antioxidants and has mild calming properties without any adaptogenic claims to evaluate.
Frequently Asked Questions
Can you drink adaptogenic teas every day?
Most adaptogenic teas are considered safe for daily use, and consistency is actually how they work best. Tulsi and ashwagandha have the most safety data supporting regular consumption. The exception is licorice root — limit it to 1-2 cups daily and take a week off every few weeks because of its effect on blood pressure and potassium levels. If you’re pregnant, nursing, or on medication, check with your doctor before making any adaptogenic tea a daily habit.
How long do adaptogens take to work?
Most people report noticing subtle changes after 2-3 weeks of daily use, with more significant effects at the 4-8 week mark. This is consistent with the clinical trial timelines — most studies run 30-60 days before measuring outcomes. Rhodiola may produce noticeable anti-fatigue effects a bit sooner, sometimes within the first week. If you’ve been drinking an adaptogenic tea daily for two months and feel nothing, it’s reasonable to try a different one.
Are adaptogenic teas safe to combine with medications?
This depends entirely on the specific adaptogen and the specific medication. Ashwagandha can interact with thyroid medications and sedatives. Licorice root interacts with blood pressure drugs, diuretics, and blood thinners. Rhodiola may interact with antidepressants. Tulsi has the fewest known interactions but can potentiate blood-thinning medications. Talk to your prescribing physician before combining any adaptogenic tea with medication — this isn’t just a standard disclaimer, these interactions are pharmacologically real.
Is brewing adaptogen roots as tea as effective as taking supplements?
Generally, no. Most clinical studies use concentrated extracts standardized to specific active compound percentages. Brewing tea from raw roots delivers lower and less consistent doses. That said, lower doses consumed regularly over time may still provide meaningful benefits — traditional medicine systems used these plants as teas for centuries before standardized extracts existed. Tea preparation also avoids some of the potency concerns with supplements, which can vary significantly between brands. If you want the clinical-trial level effects, standardized supplements are more reliable. If you want a gentler daily practice, tea is a reasonable approach.
