typically grows between 0.5 to 1 meter in height. The plant emits a slight
aromatic scent and has shallow, fibrous roots. Its stems and leaves are covered
with fine white hairs, giving them a somewhat fuzzy appearance. The leaves are
ovate, measuring approximately 2–6 cm in length, and possess toothed margins.
The flowers are small, less than 6 mm across, and can be white, pink, purple,
or blue, arranged in close terminal flower-heads. The fruit is a ribbed, black
achene about 1.25 to 2 mm long, equipped with an aristate pappus that aids in
wind dispersal. Distribution and Habitat Originally from the tropical regions of Central and South America,
Ageratum conyzoides has spread to other parts of the world, including Africa,
Asia, and the Pacific Islands. It's often found in disturbed areas, grasslands,
open forests, roadsides, and cultivated lands. Due to its rapid growth and
spread, it's considered a weed in many regions. Medicinal Properties
