Yerba Mate and Blood Pressure – Does Yerba Raise Blood Pressure?

Yerba mate and blood pressure is a question that keeps coming back to us — in emails, on the hotline and in comments. And that’s fair, because it’s a reasonable question. The answer, without beating around the bush: yerba mate contains caffeine, and caffeine can briefly raise blood pressure in some people. Usually by a few to a dozen or so mmHg, for an hour or two, most noticeably in those who don’t normally drink caffeine. That’s no reason to panic, but there’s no point pretending the issue doesn’t exist either. In this article we lay it out honestly: what caffeine does, how drinking from a matero differs from knocking back an espresso, when to talk to a doctor, and how to brew more gently if you’d like to.

Does yerba mate raise blood pressure? Short answer

Possibly, temporarily. The culprit is caffeine – the same one found in coffee, tea and energy drinks. After drinking a caffeinated infusion, blood vessels briefly constrict and blood pressure can tick upward. In people who drink yerba mate or coffee daily, the body usually adapts and the effect weakens – this is a well-documented phenomenon known as tolerance to caffeine.

Two things this article will NOT say, because there’s no basis for them: that yerba mate lowers blood pressure, or that it’s safe for everyone with hypertension. An infusion is not a medicine and doesn’t act like one – in either direction. If someone promises you that some dried leaves will “regulate” your blood pressure, keep a hand on your wallet.

How much caffeine is there anyway? It depends on the amount used and the brewing method – the range is quite wide. We broke it down in detail in a separate article: how much caffeine coffee, tea, yerba mate and energy drinks contain.

Matero is not espresso – drinking pace makes a difference

There’s one practical difference between yerba mate and coffee that’s rarely mentioned when talking about blood pressure. You drink espresso in a minute – all the caffeine hits at once. Matero is drunk differently: in small sips, with refills, over half an hour or longer. The same total caffeine dose spread over time means a gentler course – less of a sharp kick at the start.

On top of that, yerba mate carries theobromine alongside caffeine – a relative of caffeine known from cocoa, with a milder profile of action. You’ll find a full comparison of the two drinks – not just in terms of caffeine – in the article yerba mate or coffee.

One more detail to watch out for, this time unrelated to caffeine: temperature. Very hot drinks (above 65°C) aren’t a great idea for your oesophagus on their own. Yerba mate is brewed with 70–80°C water anyway, and drunk even cooler – just don’t rush your first sip.

Do you have hypertension? See your doctor first, then reach for matero

This part will be boring, because it has to be. If you’ve been diagnosed with hypertension, take blood pressure medication, or your readings fluctuate – talk to your doctor about yerba mate before turning it into a daily ritual. This isn’t just a disclaimer. Caffeine can interact with certain medications, and every body reacts differently – your doctor knows your results, we don’t.

Three rules we suggest to everyone in this situation:

• Don’t give up your medication for an infusion. No dried leaves replace therapy – yerba mate can be, at most, a pleasure alongside treatment, never instead of it.
• Measure, don’t guess. If you have a blood pressure monitor at home, check your readings before matero and an hour after, several times on different days. You’ll see in black and white how YOUR body reacts, instead of relying on other people’s opinions from a forum.
• Start gently. Weaker brewing, a smaller portion, not on an empty stomach – more on that below.

We wrote more broadly about who yerba mate might not be suitable for in the article on the possible side effects of yerba mate – worth reading before your first purchase, not after.

How to drink yerba mate mindfully – 5 practical rules

Good news: you have a lot of control over the strength of the infusion. The strength of yerba mate isn’t a feature printed on the packaging – it’s the result of how much dried leaves you use and how you brew it.

1. Start with 2 tablespoons of dried leaves instead of the classic 1/4 matero. Less dried leaves = less caffeine in the infusion. The flavour will be milder, and you’ll test your body’s reaction without overdoing it at the start.
2. Water at 70–80°C, never boiling. Boiling water makes a bitter, harsh infusion. A gentle temperature means a milder profile – and better taste.
3. Not on an empty stomach, if you’re sensitive. Caffeine on an empty stomach hits faster and harder. A matero after breakfast is a whole different level of comfort.
4. Watch how your body reacts. Heart palpitations, anxiety, shaky hands – these are signs the dose was too much. Next time, go weaker or use less.
5. Have your last matero early. Caffeine in the evening means worse sleep, and lack of sleep plus blood pressure is not a good combo. We’ve broken down the timing in our article yerba mate and sleep.

You’ll find the whole brewing technique step by step – with the leaf fill, bombilla angle and refills – in our yerba mate brewing guide.

Three variants from our shelf – from the classic to an evening blend

Let’s be upfront: every one of the yerbas below contains caffeine, and none of them is a “yerba for blood pressure” – no such product exists. What they differ in is character and added ingredients, which matters when you’re building your daily routine.

Yerba De Brasil – Doypack 0.5 kg

A classic with no additions – pure dried leaves from Rio Grande do Sul. The best starting point, because you have full control over the strength of the infusion in the dose: two spoons to try it out, more only once you know how you react.

Yerba Mate – Herbal Balance

Yerba with six herbs: rosemary, peppermint, elderberry, nettle and boldo leaf. The herbs soften the flavour profile of the infusion – less raw bitterness, more greenness. The caffeine is still there, but the character of the infusion is calmer than in the pure classic.

Yerba Mate – Relax

A blend with lemon balm and chamomile (300 g pack) – the variant chosen by people looking for a calmer daily rhythm. To be honest: it is still yerba with caffeine, so in the evening you are better off reaching for plain lemon balm – but as an afternoon matero, Relax does exactly what its name promises.

Purity of the dried leaves – that’s what we test for

When it comes to health, there’s one more thing you have real control over as a buyer: the purity of the dried leaves themselves. Our yerba grows in Rio Grande do Sul, Brazil, and is packed in Europe. Every batch is tested: GBA Polska checks for heavy metals, pesticides and PAHs, the Institute of Natural Fibres and Medicinal Plants confirms the authenticity of the dried leaves chromatographically, and J.S. Hamilton verifies compliance with the reference standard. On top of that, there’s HACCP, KIWA certification, Swiss OROTAL oversight and the Quality Certificate from the National Medicines Institute. We publish the full list of reports on our research page.

These documents don’t say anything about your blood pressure – but they say a lot about what’s NOT in your infusion. And since you drink yerba every day, that list should matter to you the most. By the way: if you’re curious what research says about yerba and cholesterol, we have a separate article on that.

Frequently asked questions about yerba mate and blood pressure

Does yerba mate raise blood pressure?

It can raise it temporarily – due to the caffeine, similar to coffee. In regular mate drinkers, the effect usually fades as tolerance builds. The simplest way to check is with your own blood pressure monitor: measure before and an hour after your infusion, on a few different days.

Can you drink yerba mate if you have high blood pressure?

This is a question for your doctor, not a yerba shop – and we say this with full conviction. Your doctor knows your results and the medications you take. If they give you the green light, start with weak brewing and monitor your readings.

Does yerba mate lower blood pressure?

There’s no basis for such a claim, and you won’t find that promise here. Yerba mate is an infusion, not a medicine – anyone claiming otherwise is selling you a fairy tale.

How much caffeine does yerba mate have compared to coffee?

It depends on the amount of leaves and the brewing method – the range is really wide. We’ve gathered specific figures for yerba mate, coffee, tea and energy drinks in this comparison.
