Plantain (Plantago major or Plantago lanceolata) is a common weed, not the banana-like fruit. Herbal traditions use the fresh or dried leaves for teas, tinctures, extracts, and topical applications.
People take plantain internally to soothe throat irritation, calm a cough, and ease occasional digestive upset. The leaf also supports respiratory comfort as a mild expectorant. Applied to the skin, it helps with minor irritations, insect bites, and small wounds.
Common forms include tea (1 to 2 teaspoons of dried leaf steeped in hot water for 10 to 15 minutes), tincture (1 to 2 mL up to three times daily), and capsules. A glycerite extract avoids alcohol. Doses vary widely by form and individual need.
Allergic reactions are possible, particularly if you react to ragweed, mugwort, or other Asteraceae family plants. Internal use can cause mild stomach upset in sensitive people. Anyone pregnant or breastfeeding should check with a healthcare professional before use.
