This palm is quite possibly the most useful of all plants for humans. It provides, food, water, shelter, and much more. Countless culinary and cosmetic uses exist for the coconut milk and oil. The husk and shells are used for fuel, charcoal, and coir, a natural fiber used in upholstery padding, sacking, plant growing media, brushes, string, rope, and fishing net. The leaves are useful for brooms, trunks for building small bridges, huts, drums, and canoes, and the roots for a dye, a mouthwash, and a medicine for diarrhea and dysentery. It is ubiquitous in lowland areas of the Hawaiian Islands, originally introduced by the Polynesians, and widely used, revered, or ignored due to their commonness. Trees need to be trimmed annually or the can create a safety hazard (falling coconuts). The rhinoceros beetle (Orycytes rhinoceros) is considered a major pest of coconut palms in Hawai'i.
