Tridax procumbens |
Tridax procumbens, commonly known as coatbuttons[1] or tridax daisy, is a species of flowering plant in the daisy family. It is best known as a widespread weed and pest plant. It is native to the tropical Americas, but it has been introduced to tropical, subtropical, and mild temperate regions worldwide. It is listed as a noxious weed in the United States and has pest status in nine states.[2]
Common names
Its common names include coatbuttons and tridax daisy in English, jayanthi in Kannada, cadillo chisaca in Spanish, herbe caille in French, jayanti veda in Sanskrit, ghamra in Hindi, Tridhara (ত্রিধারা) in Bengali, bishalya karani (ବିଶଲ୍ୟକରଣୀ) in Oriya, kambarmodi, Jakhamjudi & tantani" (कंबरमोडी, जखमजुडी & टनटनी) in Marathi, gayapaaku (గాయపాకు) & gaddi chemanthi (గడ్డి చామంతి) in Telugu,vettukaaya poondu or kinatruppasan (கிணற்றுப்பாசான்) in Tamil,[3] kotobukigiku in Japanese and tīn túkkæ (ตีนตุ๊กแก; "gecko feet") in Thai.[4]
Description
The plant bears daisylike yellow-centered white or yellow flowers with three-toothed ray florets. The leaves are toothed and generally arrowhead-shaped. Its fruit is a hard achene covered with stiff hairs and having a feathery, plumelike white pappus at one end. Calyx is represented by scales or reduced to pappus. The plant is invasive in part because it produces so many of these achenes, up to 1500 per plant, and each achene can catch the wind in its pappus and be carried some distance. This plant can be found in fields, meadows, croplands, disturbed areas, lawns, and roadsides in areas with tropical or semi-tropical climates.[citation needed] It is listed in the United States as a Noxious Weed and regulated under the Federal Noxious Weed Act.[citation needed]
Use in traditional medicine
Traditionally, Tridax procumbens has been in use in India for wound healing and as an anticoagulant, antifungal, and insect repellent.[citation needed] The juice extracted from the leaves is directly applied on wounds. Its leaf extracts were used for infectious skin diseases in folk medicines. It is used in Ayurvedic medicine for liver disorders, hepatoprotection, gastritis, and heartburn.[5] Tridax procumbens is also used as treatment for boils, blisters, and cuts by local healers in parts of India.[6]
Chemical constituents
The flavonoid procumbenetin has been isolated from the aerial parts of Tridax procumbens. Other chemical compounds isolated from the plant include alkyl esters, sterols,[7] pentacyclic triterpenes,[7][8] fatty acids,[9] and polysaccharides.[10]
