5 Traditional Reasons Peruvians Brew Pulmonaria (Lungwort) Tea

September 22, 2026

Walk into a botica in Lima during the first cool weeks of fall and you'll spot small paper bags of dried pulmonaria leaves stacked next to the eucalyptus and the matico. Most tourists walk right past it. Most Peruvians don't.

Pulmonaria (Lungwort) isn't native to Peru. It made its way over from Europe centuries ago, folded into the same wave of herbal knowledge that brought manzanilla and toronjil into the Andean kitchen. But it settled in fast, and today it's a standing entry in the home medicine cabinet for anyone dealing with a scratchy throat or a chest that feels heavier than it should.

Here are five reasons it's stuck around this long.

1. The name isn't a coincidence

"Pulmonaria" comes straight from the Latin for lung, and the association goes back to medieval Europe, where the plant's spotted leaves were thought, under the old doctrine of signatures, to resemble diseased lung tissue. The visual logic was wrong, but the herbalists who kept reaching for it generation after generation weren't wrong that the plant did something. Its use for coughs, bronchitis, and general chest discomfort shows up in monastic herbals as far back as the 12th century, including the writings of Hildegard of Bingen.

2. It's mostly mucilage, and that's the point

Lungwort leaves are high in mucilage, the same slippery plant polysaccharide that makes okra slimy and marshmallow root soothing. Steep the dried leaves and that mucilage coats the throat and upper airway, which is why the tea feels calming on a raw throat within a few sips. Combine that with the tannins and expectorant compounds also present in the leaf, and traditional use frames the tea as loosening a stubborn cough rather than just numbing it.

3. Peruvian households treat it as a season-changer

Fall on Peru's coast brings the garúa, the low gray mist that settles over Lima and doesn't lift until spring. It's prime season for the kind of lingering cough that never quite turns into a real cold but never quite goes away either. A cup or two of pulmonaria in the evening is one of the standard responses, brewed the same simple way as chamomile: a teaspoon of loose leaf, water just off the boil, five to seven minutes covered.

4. It plays well with other respiratory herbs

You'll rarely find pulmonaria drunk completely on its own in a Peruvian kitchen. It shows up blended with eucalipto or a respiratory blend like Bronquiosan, each contributing something different: eucalyptus for the vapor and cooling, menthol-like clearing sensation, matico for its own long folk history with tissue healing, pulmonaria for the coating, soothing mucilage underneath it all. If you already keep dried eucalyptus in the cupboard, pulmonaria is an easy herb to fold into the same evening routine. Browse our full respiratory support collection if you're building one out.

5. The research is thin, and that's worth saying plainly

We'd be doing you a disservice if we oversold this. Modern clinical research on Pulmonaria officinalis is limited. What exists points to real antioxidant activity and anti-inflammatory compounds in lab studies, plus centuries of consistent traditional use for respiratory complaints across Europe and, later, Peru. But there's no large human trial proving it shortens a cold or clears a cough faster than time alone would. Treat it as a comforting, low-risk part of your evening routine, not a substitute for seeing a doctor about a cough that lingers past two or three weeks, comes with fever, or gets worse instead of better.

A quick word on caution

Pulmonaria belongs to the same plant family as borage and comfrey (Boraginaceae), a family that in some species carries trace pyrrolizidine alkaloids, compounds that in large accumulated doses can stress the liver. Dried Pulmonaria officinalis sold for tea is generally considered low-risk for occasional use, but out of that same family caution, treat it as an occasional herb rather than an everyday all-day sipper. Skip it if you're pregnant, nursing, or managing existing liver disease, and check with your doctor before adding it to your routine if you're on prescription medication.

If your cupboard already has eucalyptus in it, pulmonaria is a natural, gentle addition for the months when the air turns damp and coughs linger a little longer than they should.
