Benefits of Yerba Mate Tea: What to Know Before You Try It

Yerba mate is a traditional South American herbal drink brewed from the leaves of the Ilex paraguariensis plant. It's prized for its natural caffeine content, antioxidants and a flavor somewhere between green tea and coffee.

What Is Yerba Mate?

Mate, pronounced "mah-tay," comes from a Guaraní word meaning roughly "the vessel that holds the drink." It's traditionally sipped hot through a metal straw from a hollowed gourd, though loose-leaf and tea-bag versions are common outside South America.

Potential Benefits of Yerba Mate

May Support Energy and Focus

Yerba mate naturally contains caffeine along with small amounts of theobromine and theophylline, compounds that may provide a steadier energy lift than coffee for some people. It also contains L-theanine-like compounds associated with calm alertness, which is why many drinkers describe the effect as focused rather than jittery.

Rich in Antioxidants

Mate is a good source of polyphenols, including chlorogenic acid, which are associated with reduced oxidative stress in the body. Antioxidant-rich diets are linked to lower long-term disease risk in general, though mate itself is not a treatment for any condition.

May Support Healthy Cholesterol Levels

Some animal and human studies point to a possible lipid-lowering ("antilipidemic") effect from regular mate drinking, and some heavy mate drinkers have shown lower lipid profiles in observational research, according to Memorial Sloan Kettering's review of mate. The evidence is mixed and mostly observational, so mate should be seen as a possible complement to — never a replacement for — a healthy diet and any medication prescribed for cholesterol management.

May Support Digestion

Traditionally, mate has been used to support regular digestion, and some drinkers find it eases occasional bloating. Robust clinical evidence for this is limited.

Side Effects and Precautions

• Yerba mate contains caffeine, comparable to a cup of coffee per serving, so limit intake if you're sensitive to caffeine or drink it alongside other caffeinated beverages.
• Regularly drinking large amounts of mate over many years has been linked in observational studies to a higher risk of several cancers, including esophageal, bladder, lung and head and neck cancers; drinking it very hot appears to add to this risk, so stick to moderate amounts and let it cool from scalding before drinking (Memorial Sloan Kettering).
• Mate isn't recommended during pregnancy or breastfeeding, and it should be avoided alongside cardiac medications or other stimulants without your doctor's guidance. Rare cases of acute hepatitis have also been reported, so tell your doctor about any liver condition.
• If you're managing high blood pressure or a heart condition, talk to your doctor before making mate a daily habit.
• Avoid mate close to bedtime, since its caffeine content can affect sleep.

FAQ

The Bottom Line

Yerba mate is a flavorful, antioxidant-rich alternative to coffee that may support energy, focus and healthy cholesterol levels as part of a balanced diet. Keep servings moderate, drink it warm rather than scalding hot to limit long-term cancer risk, and check with a doctor if you have an underlying health condition.
