Maranta arundinacea

About Arrowroot

Arrowroot (Maranta arundinacea) is a herb used in the Caribbean Folk Medicine tradition to help with Digestive Issues, Diarrhea, Wound Healing, and UTI. The aerial parts and leaves are the parts traditionally used, used both internally and topically.

Botanical background

Maranta arundinacea, also known as arrowroot, maranta, West Indian arrowroot, obedience plant, Bermuda arrowroot, araru, ararao or hulankeeriya, is a large, perennial herb found in rainforest habitats. Arrowroot flour is now produced commercially mostly in St. Vincent and the Grenadines. Arrowroot was one of the earliest plants to be domesticated for food in northern South America, with evidence of exploitation or cultivation of the plant dating back to 8200 BCE.

Quality tips

When buying Arrowroot, look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products โ€” quality varies enormously.
