Phyllanthus urinaria
Chamber bitter, scientifically known as Phyllanthus urinaria, is a small, herbaceous plant that is native to tropical Asia and has naturalized in many warm regions worldwide. It is also known as gripeweed, shatterstone, or stonebreaker in various languages and regions.
This annual plant grows up to 60 cm tall and is characterized by reddish stems, small alternate leaves, and tiny flowers that appear along its leaf axils. It produces round, warty capsules containing seeds.
Commonly found in disturbed areas, roadsides, gardens, and cultivated lands, it thrives in warm, humid climates with well-drained soils but can tolerate partial shade.
Chamber bitter is considered invasive in many regions due to its prolific seed production, adaptability to various environments, and ability to outcompete native plants.
Despite its invasive nature, chamber bitter is valued in traditional medicine for its properties as a diuretic and remedy for liver and kidney ailments, jaundice, and fever. Its bioactive compounds have shown potential in antiviral and antibacterial applications.
