Description

• Eclipta prostrata, commonly known as false daisy or yerba de tago, is an annual herb in the sunflower family (Asteraceae). It has spreading or upright stems, opposite leaves that are narrow to lance-shaped, and small white flower heads with a central cluster of tiny disc florets surrounded by short white ray florets. The stems often root at the nodes when they contact moist soil. The plant has a long history of use in traditional medicine, although its safety and effectiveness depend on the preparation and intended use.

Range

• Eclipta prostrata has a broad distribution throughout tropical and subtropical regions worldwide. Its native range is generally considered to include tropical America and parts of Asia, although its original distribution is complicated by its long history of human dispersal. It is established in Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• False daisy commonly grows in moist, sunny habitats, including streambanks, pond margins, ditches, wetlands, irrigated fields, gardens, and other disturbed areas. It favours damp soils and is often abundant in seasonally wet ground. Its ability to grow in disturbed habitats and produce numerous seeds helps it spread readily in tropical and subtropical environments.
