ʻAeʻae is a part of the Plantaginaceae or Plantain family. It can grow in water and is used in modern restoration efforts to clean waterways. This is due to ʻAeʻae’s natural ability to soak up unwanted nutrients (phytoremediation). ʻAeʻae is an antioxidant and is used in medicine to help with brain function. Traditional Hawaiian uses are unknown.
