What is Plantain?

Plantain is a low, flat-growing weed with broad, ribbed leaves. The plant meant here is Plantago major. Its leaf is the part used in home remedies.

It is not the starchy cooking banana, which shares the name. It grows in lawns, paths and waste ground across most of the world.

Folk healers used it mostly on the skin, for stings, scrapes and rashes. It was also drunk as a tea for coughs and loose bowels.

Here is the honest verdict. Human evidence is thin, and most findings come from lab and animal work. Long use in tradition is not proof that it works, and not proof that it is safe.

How does Plantain work?

No one has shown in people how plantain works, or how much it does.

In test-tube studies, leaf extracts slow the growth of some bacteria. In animal studies, they calmed swelling and helped skin wounds close faster. Whether the same thing happens on your skin is not established.

Two ideas come up again and again. One is mucilage, a slimy fibre that may coat and soothe sore tissue. The other is aucubin and allantoin, which may support skin repair.

Both ideas rest on lab and animal work. Neither has been confirmed by good trials in people.

The leaf also holds tannins, which tighten tissue in lab tests. That is the usual reason given for its old use in diarrhoea. Again, this is a plausible idea rather than a tested one.

What forms does Plantain come in?

You will meet plantain in a handful of simple forms.

Fresh leaf is the oldest form. People crushed or chewed a leaf and laid it on the skin.

Dried leaf is sold loose or in tea bags. It is steeped in hot water as an infusion.

Liquid extracts come as tinctures in alcohol or glycerine. Dropper bottles are the usual packaging.

Skin products include salves, ointments, infused oils and creams. Plantain is often blended with calendula or comfrey.

You may also see capsules of powdered leaf. Cough syrups containing plantain are sold in Europe.

Watch the label. The word plantain can also mean the cooking banana, Musa. Psyllium husk is a different Plantago species, so check for the name Plantago major.

Where it comes from:

Plantain was a fixture of American folk and Eclectic practice in the 1800s and early 1900s. Eclectic physicians listed it for bites, stings, small wounds and sore throats.

Settlers carried the plant over from Europe. It spread along trails and roadsides, and some Native peoples called it White Man's Foot.

Older English and European herbals had used it for much the same jobs. An Anglo-Saxon text names it among nine sacred herbs.

Home use continued through the twentieth century as a simple first-aid plant. That standing rests on long habit and written custom, not on trials.

What does Plantain help with?

• Insect bites and stings, used on the skin: Folk healers crushed a fresh leaf and pressed it on the sting to ease itch. In animal studies, leaf extracts reduced swelling and irritation. No good human trial has tested it on bites, so treat this use as unproven.
• Minor cuts, scrapes and grazes: Plantain was a standard wound herb for small, clean injuries. In animal studies, leaf extracts sped up wound closure. Human proof is missing. Washing the wound and covering it still matter far more.
• Itchy or irritated skin: Salves were used on dry, itchy or chafed skin. Mucilage and allantoin may soften and soothe, based on lab work and cream research. Trials in people with eczema or rashes are lacking.
• Cough and sore throat: Plantain tea and syrup were common for a dry, tickly cough. The slimy fibre may coat a sore throat. That is a reasonable idea, not a proven effect. Most cough research used the related ribwort plantain, and usually in mixed products.
• Short-term mild diarrhoea: Leaf tea was taken for loose bowels, most likely for its tannins. Tannins tighten tissue in lab settings. No trial shows that plantain shortens diarrhoea in people. Fluid loss is the real danger, so rehydration comes first.
• Sore gums and mouth irritation: Herbalists used plantain rinses for sore gums and mouth ulcers. A few small early studies have looked at plantain mouth rinses for gum swelling. They are too small and too few to call this effective.

Which foods are rich in Plantain?

1. Young plantain leaves, cooked as a green
2. Plantain seed, used like a small grain in some regions

Practical Tips:

Young leaves are edible when cooked, and taste a little like spinach. Older leaves turn tough and stringy.

Food amounts are small and are not a remedy. Only eat leaves from clean ground you know well.

What are the side effects of Plantain?

• Mild stomach upset or nausea
• Loose stools or bloating with large amounts
• Skin rash or itching from contact with the fresh leaf
• Sneezing, itchy eyes or wheeze in people allergic to plantain pollen
• Rare allergic reaction with hives, swelling or trouble breathing
• Illness from poor-quality or wrongly identified wild leaves

Good to know:

Most people who use plantain on the skin or as a tea report no trouble. Reported effects are usually mild and settle when you stop.

Allergy is the main real risk. People who react to psyllium or to plantain pollen can react to the leaf.

Product quality is the other risk. In 1997, a batch of plantain sold in the United States was contaminated with digitalis, a heart-active plant, and a user developed a heart rhythm problem.

Wild picking adds its own hazard. Roadside, sprayed or dog-fouled ground can leave the leaf dirty or toxic.

How much Plantain should you take?

• Recommended daily: Plantain is not standardised, so there is no agreed dose. Labels on dried leaf often list about 2 to 4 grams of leaf per cup of tea. Tincture labels commonly list a few millilitres, up to three times a day. Those are label figures, not advice for you. Follow the pack you own. Ask a pharmacist or doctor first if you take any medicine. Skin products are applied to the area named on the label. Never pack any preparation into a deep or dirty wound.
• Best time of day: Timing does not matter much. Tea for a cough is often taken when the cough bothers you, including at bedtime. Skin products are used when the area needs them.
• With or without food: Either is fine. Taking tea or tincture with food may reduce mild stomach upset. Leave about two hours between plantain and other pills, because the fibre may slow how drugs are taken up.
• Time to effect: On skin, people report a cooling, soothing feel within minutes. For a cough or loose bowels, any change would be expected over a day or two. None of this is backed by solid human trials. It may do nothing at all for you. If your problem is getting worse, stop and get it checked.
• How long to take it: Traditional use was short and aimed at a passing problem. Skin and tea use ran for days, not months. Many labels say to stop after a week or two if nothing changes. No trial has tested daily long-term use in people. Long-term safety is unknown, so open-ended use is not supported.
