Iced Toronjil Tea: Peru's Calming Lemon Balm for Summer

May 25, 2026

Walk into a Peruvian kitchen on a hot afternoon and there's a good chance someone has a jar of toronjil steeping on the counter. Toronjil is lemon balm (Melissa officinalis), a soft, lemony herb in the mint family, and it's one of the most common calming teas in the country. Most people drink it hot. But in late May, with summer pushing in, it turns into something better: a cold, faintly citrusy iced tea that settles your stomach and your nerves at the same time.

Here's why it belongs in your fridge this season, and how to make it without turning it bitter.

What toronjil actually is

Lemon balm has been grown around the Mediterranean for more than 2,000 years, and Spanish settlers brought it to Peru, where it slipped easily into home gardens and herb markets. Crush the leaves and they smell like lemon with a hint of mint. There's no actual citrus in it and no caffeine either, which is part of why it works as an evening or hot-weather drink. You can have a tall glass at 4pm and still sleep fine.

In Lima markets you'll find it sold fresh by the bunch, dried in bags, and blended into calming mixes alongside valerian and chamomile. The flavor is gentle, closer to a soft herbal lemonade than a strong green or black tea.

Why it makes sense in summer

Most of what we reach for when it's hot is either sugary or caffeinated. Toronjil is neither. Brewed and chilled, it's naturally a little sweet and clean-tasting, so you can skip most of the sugar. Because there's no caffeine, it won't leave you jittery or dehydrated the way three iced coffees might.

Then there's the calming angle. Heat makes people irritable and restless, and lemon balm has a long reputation as a settle-down herb. A cold glass after a sweaty afternoon does double duty.

What the research says, and doesn't

Lemon balm is one of the better-studied calming herbs, though better-studied still means small trials. Several have looked at it for mild anxiety, stress, and sleep quality, often combined with valerian, and found modest improvements in how relaxed or rested people felt. A few studies suggest it may ease occasional indigestion and gas, which fits its traditional use after heavy meals.

The effects are gentle. Lemon balm isn't a sleeping pill, and it won't flatten real anxiety. Think of it as a nudge toward calm rather than a switch you flip. The research is still early and we're not a doctor, but for everyday stress and restlessness, the evidence and a few centuries of use line up reasonably well.

How to brew iced toronjil

The trick with iced lemon balm is to brew it strong and warm first, then cool it, rather than steeping it in cold water from the start. Cold water won't pull much flavor out of the leaves.

For a pitcher, about 1 liter:

Use 3 to 4 tea bags, or 3 to 4 tablespoons of loose dried toronjil.
Pour in roughly 2 cups of just-off-the-boil water. Fully boiling water can scorch the leaves and turn them bitter.
Steep 6 to 8 minutes, then pull the bags or strain the leaves. Leaving them in longer makes it bitter, not stronger.
Top up with cold water to fill the liter, then refrigerate until cold.
Serve over ice with a slice of lemon. Add a little honey only if you want it.

If you grow lemon balm or buy it fresh, use a generous handful of crushed leaves in place of the dried amount. Fresh is milder, so don't be shy with it.

Good things to add

Toronjil plays well with other Peruvian herbs. A few sprigs of hierba luisa (lemongrass) deepen the citrus note. A little muña or mint makes it more cooling. For an evening version, our Nerviosan blend already pairs lemon balm with valerian and burnet for a stronger wind-down. If you prefer loose leaf so you can dial in the strength yourself, the loose-leaf toronjil is the same herb in bulk.

Who should go easy

Lemon balm is gentle and safe for most people. Still, a couple of notes.

Thyroid medication. Some research suggests lemon balm may interfere with thyroid hormone activity, so check with your doctor if you take thyroid medicine.
Sedatives and sleep aids. Because it's mildly calming, it can add to the effect of prescription sedatives. Don't stack them without asking first.
Pregnancy. Occasional tea is generally considered fine, but there isn't much research, so keep it moderate and ask your doctor.

For everyone else, a cold glass of toronjil is about as low-risk as a summer drink gets. Brew a pitcher in the morning, keep it in the fridge, and you've got something calming to reach for when the afternoon heat hits. You'll find it and the rest of our calming teas in the sleep and mood support collection.
