(Mimosa Pudica L.)
Mimosa pudica is a sensitive plant native to South America and has spread widely, becoming a serious weed throughout the world's tropical regions. However, this weed can be cultivated as a ground cover or green manure and has been identified as having potential for phytoremediation of arsenic-contaminated areas in Thailand. Occasionally, Mimosa pudica is also grown as an ornamental plant. In Guadeloupe, Trinidad and Tobago, Cuba, Brazil, India, Malaysia, and the Philippines, Mimosa pudica is an important source providing pollen for Italian honeybees (Apis mellifera) and other bees. Additionally, Mimosa pudica offers good health benefits and has been used as an ingredient in traditional medicine in various countries. In Indonesia, Malaysia, and Thailand, the plant is used to treat insomnia and as a poultice to treat swelling. In South America, it is considered an emetic and is also used to treat diarrhea and dysentery. In Ayurvedic medicine, this plant is used as an anti-asthmatic, aphrodisiac, analgesic, and antidepressant.
Mimosa pudica is typically found growing along roadsides, vacant lots, grasslands, garbage dumps, and disturbed areas in many tropical regions, from sea level up to an altitude of about 1,300 meters above sea level (m.a.s.l.). This plant can grow in various soil types, including low-fertility soil, is capable of tolerating waterlogging and resisting drought, and the soil pH is in the range of 6–7 and tolerates 5–7.5. It prefers a position with full sun (about 6–8 hours per day) but is intolerant of shade. It can grow well in areas with average annual rainfall in the range of 1,000–2,000 mm, and annual daytime temperatures in the range of 22–28 °C, but can tolerate 10–32 °C.
