PlantainPlantago lanceolata, Plantago major
Plantain (not to be confused with the relative of the banana known by the same name) is a small weed often found in cultivated fields and at the edge of lawns. Traditionally, the crushed leaves were applied to the skin to treat wounds and bites, a leaf tincture was used for coughs, and the dried leaf was taken internally for the treatment of bronchitis, ulcers, epilepsy, and liver problems.
What is Plantain Used for Today?
Very weak evidence, too weak to rely upon at all, has been used to indicate that topical plantain is helpful for skin conditions, including poison ivy and eczema
Plantain extracts do appear to have anti-inflammatory effects, at least in the test tube.
Contrary to some reports, one study found that plantain does not have diuretic (kidney-stimulating) effects.
A typical dose of plantain for oral use is 1–3 grams three times daily. 11
Plantain contains active substances in the iridoid glycoside family, especially aucubin, catalpol, and acteoside.
Plantain appears to be relatively safe, but comprehensive safety studies have not been performed.
Plantain grown in soil contaminated with heavy metals such as thallium or antimony may develop relatively high concentrations of these potential toxins. 15,16
In 1997, the FDA reported that some “plantain” available for sale on the herb market was contaminated with similar-appearing foxglove (digitalis), an herb with potent and potentially toxic effects on the heart.
Safety in pregnant or nursing women, young children, or individuals with liver or kidney disease has not been established.
