Effective Dosage
No established dose
What the Science Says
Plantain leaf (Plantago major or lanceolata) is a common wild plant used for centuries in traditional medicine across Europe and Asia. It contains compounds like aucubin, mucilage, and tannins that are thought to soothe irritated mucous membranes in the throat and digestive tract. Traditional uses include calming mild coughs, supporting respiratory health, and easing minor digestive discomfort, though these uses are based largely on historical practice rather than modern clinical trials.
What It Doesn't Do
Not proven to treat infections, asthma, or chronic respiratory disease. No clinical evidence it heals wounds when taken orally. Won't replace prescribed medications for any condition. Not a proven anti-inflammatory treatment in humans. No evidence it detoxifies the body or boosts immunity in any meaningful clinical sense.

Absorption & Bioavailability
Unknown — no pharmacokinetic data available from provided studies. Mucilage compounds are largely active in the gut rather than absorbed systemically.
Red Flags to Watch For
- No clinical trials were found in the provided data — all uses are based on traditional or pre-clinical evidence only
- May interact with blood-thinning medications (warfarin) due to potential vitamin K content
- Products vary widely in preparation (tea, extract, capsule) with no standardized dosing or quality benchmarks
- Allergic reactions are possible, especially in people sensitive to Plantago pollen
- Often combined with other herbs in products, making it impossible to attribute any effect to plantain leaf alone
