Plantain Leaf / Plantago major & Plantago lanceolata
Actions: Diuretic, alterative, anti-inflammatory, aperient
No, this isn't the banana-like fruit. Yes, this is the plant that is almost as common in your grass as dandelion, and yes it's medicinal.
I love introducing people to this plant because it's so prevalent and immediately usable. If you're working or walking outside and get bitten or stung find some plantain, chew or mash the leaf up, and stick it on to soothe the spot and draw anything out.. I infused plantain into the oil for my hand salve because it works so well at soothing the skin.
An infusion of the leaves in water tastes rich and green and can be used for soothing inflammation-- coughs, urinary tract infections, mild bronchitis. The seeds can be used for constipation.
