Tea for High BP: Noon Chai Salt, Mulethi, Gudhal and Caffeine
Mulethi (licorice root) tea is the one to stop reaching for if you have high blood pressure: it makes the body hold salt and water and lose potassium, so BP can climb even on medicine. Salty noon chai made with baking soda is the next worry, and strong caffeine can give some people a short rise. Most other qehwas are neutral. Gudhal and green tea may help a little, not enough to replace a tablet. Here’s how each common tea sits with BP, plus the numbers that matter.
Quick facts
- Raises BP: mulethi (licorice), salty noon chai with soda, very strong caffeine in sensitive people
- Neutral: elaichi, saunf, zeera, pudina, babuna, ginger in food amounts, blue tea
- Modest help at most: gudhal (hibiscus), green tea; can add to medicine
- High BP: 140/90 at the clinic, about 135/85 at home
- Emergency: 180/120 with chest pain, breathlessness, severe headache, weakness or vision change

The tea that raises BP: mulethi (licorice root)
Mulethi is sweet, soothing on a sore throat, and sold in almost every pansar shop. It’s also the one qehwa that works directly against blood pressure control. Its main compound, glycyrrhizin, blocks an enzyme the kidneys use to keep salt balance normal. The result: the body holds on to sodium and water, and loses potassium.
That means three things for someone with high BP. Readings can rise even while you take your tablets. Ankles can swell. And low potassium brings cramps, weakness and, at worst, an irregular heartbeat, which is especially risky with water pills that also drop potassium. The effect builds over days to weeks, so a daily mulethi habit is the concern, not one cup. Our mulethi tea guide gives the full picture.
Watch for hidden licorice too: some joshanda sachets, cough lozenges, “throat” teas and herbal digestive blends include it. Read the ingredient list for mulethi, licorice or glycyrrhiza.
Go to emergency care for a reading of 180/120 or higher with chest pain, breathlessness, a severe headache, confusion, blurred vision, or weakness or numbness on one side. If you’re at 180/120 without symptoms, rest for 5 minutes, recheck, and contact your doctor the same day. Never stop, lower or change BP medicine because a tea seems to be working; take your readings to the clinic instead.
Noon chai and salt: the hidden sodium in pink tea
Kashmiri noon chai (pink tea) gets its colour from green tea leaves boiled with a pinch of baking soda, and its taste from salt. Both add sodium. A typical cup can carry around a quarter teaspoon of salt, and the soda adds more on top. The daily target for adults is under 5 g of salt, about one level teaspoon, from everything you eat.
So one cup at a wedding isn’t the problem. Two or three cups every day, on top of roti, achaar and namkeen, can be. If you love it:
- Make it at home and add salt at the table, a small pinch per cup, rather than salting the pot.
- Use the smallest pinch of soda that still gives you the pink.
- Keep it to an occasional cup, not a daily habit.

Is karak tea good for high blood pressure? Caffeine explained
Caffeine can raise blood pressure for a few hours, most noticeably in people who don’t usually drink it. Regular drinkers build up partial tolerance, so the rise is smaller. For most people with high BP, 3 or 4 ordinary cups of chai a day is fine.
Karak is a different animal. It’s boiled long and dark, often with extra leaf, so each cup carries more caffeine than a normal doodh patti. Add condensed milk and sugar and it becomes a weight problem too, and extra weight is one of the biggest drivers of high BP.
One practical rule: don’t check your BP within 30 minutes of chai or coffee. The reading will be higher than your true resting level. Our guide to checking BP at home the right way covers the rest of the routine.
Qehwa for high blood pressure: which teas are neutral, which may help
| Tea | BP effect | Note |
|---|---|---|
| Gudhal (hibiscus) | May lower slightly | Can add to medicine; dizziness on standing |
| Green tea | Small, inconsistent | Plain, not bottled; contains caffeine |
| Elaichi (cardamom) | Neutral | A pleasant way to cut sugar |
| Ginger | Neutral in food amounts | Ask first if you take a blood thinner |
| Dalchini (cinnamon) | No reliable effect | Cassia has coumarin; avoid strong daily brews |
| Butterfly pea (blue tea) | No good evidence either way | A colourful caffeine-free drink, not a remedy |
| Saunf, zeera, pudina, babuna | Neutral | Good caffeine-free evening options |
| Mulethi (licorice) | Raises BP | Avoid with high BP |
Gudhal (hibiscus): honest about the evidence
Of all the herbal teas, gudhal has the most interest behind it for blood pressure, and the effect seen is modest at best. That’s not the same as “gudhal lowers BP”, and it certainly isn’t a reason to skip a tablet. The practical risk is the opposite one: on top of your medicine it may add enough to make you lightheaded. It’s also not for pregnancy. Recipe and cautions are in our gudhal tea guide.
Blue tea and BP
Searches for “butterfly pea flower side effects blood pressure” are common. There isn’t good human evidence that blue tea raises or lowers BP in a meaningful way. It’s a pretty, caffeine-free cup, and that’s the honest summary.
Myth: if a tea brings my BP down, I can stop my tablets
People believe it because a relaxed evening with a warm cup and a lower reading feel connected. But BP swings through the day for dozens of reasons, and any help from a tea is small next to a tablet. Stopping medicine lets BP drift back up quietly, with no symptoms, which is why high BP damages the heart, kidneys and brain without warning. Keep the tea if you enjoy it. Keep the medicine unless your doctor changes it.
A cup of qehwa can sit beside your BP tablet. It can’t sit in its place.
A BP-friendly evening qehwa
Caffeine-free, salt-free and pleasant enough to replace a late chai. Makes one cup.
- Bring 250 ml of water to the boil.
- Add 1 crushed green elaichi pod and half a teaspoon of lightly crushed saunf.
- Simmer for 2 minutes, then turn off the heat.
- Add 3 or 4 fresh pudina leaves, cover, and steep for 3 minutes.
- Strain. Skip the sugar; a thin slice of lemon lifts the taste.
In Unani thinking, mulethi is valued for the chest and throat but used with caution in people of a “hot” temperament with a flushed face and headaches, a description that overlaps oddly well with high BP. Elders reached for saunf and elaichi as everyday cooling, calming flavours instead.

Tea and high BP: questions people ask
Which qehwa is good for high blood pressure?
Caffeine-free qehwas such as elaichi, saunf, zeera, pudina and babuna are safe, neutral choices. Gudhal may lower BP slightly but can add to medicine. None of them replace BP tablets.
Is karak tea good for high blood pressure?
Not really. Karak is strong in caffeine and usually made with condensed milk and sugar. An occasional cup is fine, but a daily habit adds caffeine and weight, both of which work against BP control.
Is cardamom tea good for high blood pressure?
Elaichi tea is a good neutral choice, and a useful way to enjoy a cup without sugar. There isn’t reliable evidence that it lowers BP on its own.
Does mulethi raise blood pressure?
Yes. Licorice root makes the body hold salt and water and lose potassium, which can raise BP and cause swelling and muscle weakness. People with high BP, heart or kidney disease should avoid it unless their doctor agrees.
Is noon chai bad for high BP?
Salty noon chai adds sodium from both salt and baking soda. An occasional cup is fine, but daily cups add up. Make it at home with less salt if you enjoy it.
Does ginger tea raise blood pressure?
No, ginger in food amounts isn’t known to raise BP. The caution with ginger is for people on blood thinners, who should ask before making strong ginger tea a daily habit.
Can gudhal tea replace BP medicine?
No. Any effect from hibiscus is modest and not reliable enough to replace treatment. Never stop or lower your medicine because of a tea; bring your readings to your doctor.
Does butterfly pea (blue) tea affect blood pressure?
There’s no good evidence it does either way. It’s a caffeine-free, colourful drink, but not a BP remedy.
What BP reading is an emergency?
180/120 or higher with chest pain, breathlessness, a severe headache, confusion, blurred vision, or weakness on one side needs emergency care now. Without symptoms, rest, recheck and call your doctor the same day.
Can I drink chai if I have high BP?
Yes, most people can have 3 or 4 ordinary cups a day. Cut the sugar and full-cream milk, and don’t check your BP within 30 minutes of a cup.
