While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

Summary:
Arrowroot refers to any plant of the genus Maranta, but the term is most commonly used to describe the easily digestible starch obtained from the rhizomes of Maranta arundinacea. Arrowroot is used in the form of a starchy powder dried from the milky liquid extracted from the grated plant rhizome. Traditionally, arrowroot has been used as a remedy for diarrhea, possibly due to its high starch content.

Uses
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
