Yerba Mate and Nicotine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Yerba Mate interacts with whole categories of medication. Nicotine falls into 2 of those categories, so it can interact with Yerba Mate in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

STIMULANT DRUGS

1 of 2

Why this applies to Nicotine

Nicotine falls under STIMULANT DRUGS — the group Yerba Mate interacts with.

Theoretically, concomitant use of stimulant drugs and yerba mate might increase stimulant adverse effects.
Yerba mate contains caffeine. Due to the CNS stimulant effects of the caffeine, concomitant use can increase the risk of adverse effects.
Severity Moderate Likelihood Probable Evidence C

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both yerba mate and nicotine are stimulants. Yerba mate carries a good amount of caffeine, and nicotine (whether you're using a patch, gum, lozenge, or inhaler to quit smoking) already revs up your nervous system. Stack them together and the stimulant effects can pile on.

That means you might notice things like a faster or pounding heartbeat, jitteriness, feeling shaky, trouble sleeping, an upset stomach, or feeling more anxious. None of this is usually dangerous for a healthy person, and this caution is based mostly on expert opinion rather than hard studies. A cup or two of mate is unlikely to be a big deal, but heavy intake could leave you feeling wired. If you have heart concerns or notice these symptoms, check with your pharmacist or doctor.

NICOTINE

2 of 2
Theoretically, the caffeine in yerba mate might increase risk of hypertension when used concomitantly with nicotine.
Yerba mate contains caffeine. Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly.
Severity Moderate Likelihood Probable Evidence D

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both yerba mate and nicotine are stimulants for your heart and blood vessels. Yerba mate contains caffeine, and when you pair caffeine with nicotine (whether that's from a patch, gum, lozenge, or inhaler like Nicoderm CQ or Nicorette), their effects can stack up. Studies have shown the combination can nudge your heart rate up and raise blood pressure, in one case by about 10/12 mmHg.

This is based mostly on how these two work together rather than a long track record, so it's more of a theoretical caution than a red alert. Still, if you notice a racing heart, jitteriness, or feel your blood pressure creeping up, that's worth paying attention to. If you have high blood pressure or heart concerns, chat with your pharmacist or doctor before regularly mixing the two.

This page covers Yerba Mate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nicotine page lists 64 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Peyote (major), Rauvolfia Vomitoria (major) and Sida Cordifolia (major).

By severity: 5 major · 46 moderate · 13 minor.

From our pharmacist’s overview on the Nicotine page

“Nicotine itself is a stimulant, whether it comes from a Nicoderm CQ patch, Nicorette gum, or a Nicotrol inhaler, so treat this list with genuine care. Of the 64 supplements and herbs on file, 44 add more stimulation on top of the nicotine, which can push heart rate and blood pressure higher than either would alone.”

About Yerba Mate

What is Yerba Mate?

Yerba Mate
  • Energy and alertness
  • Weight loss
  • Mental focus
  • Digestive support
  • Antioxidant support

Yerba mate is a caffeine-containing herbal beverage from South America that is widely enjoyed for its stimulating, coffee-like effects. While it is rich in antioxidants and is being studied for weight, blood sugar, and cholesterol, strong human evidence for most health claims is limited. Drinking very hot mate over many years has been linked to higher risk of certain cancers, so enjoy it warm and in moderation.
