Description: Urena lobata, commonly known as Caesarweed, Congo jute, or Bur Mallow, is a variable, erect, subshrub or shrub that can grow up to 3 meters tall. The stems are covered with star-like hairs and are often tinged purple. The leaves are greyish-green, egg-shaped or lobed, and have toothed margins with soft, short hairs on both sides. The plant produces small, pink-violet, hibiscus-like flowers, and its fruits are dry, dehiscent capsules that split into smaller fruitlets known as mericarps​​​​​​.

Distribution and Habitat: Urena lobata is pantropical, found in tropical and subtropical regions across the world. It grows in a variety of habitats including forests, grasslands, and areas of ecological disturbance such as eroded places, crop plantations, and pastures. It is also tolerant of salt spray and moderately saline soils​​​​​​.

Medicinal Properties: Urena lobata is widely used in traditional medicine. The leaves and roots are employed to treat a variety of ailments:

  • Gastrointestinal Issues: Juice from the leaves or roots is used to treat colic, stomach-ache, diarrhea, and dysentery.

  • Reproductive Health: A decoction of an old plant boiled with eggs is used to induce abortion. Additionally, an infusion of the roots aids in difficult childbirth.
  • Skin Conditions: A lotion made from the plant is applied to treat yaws and headaches, and the whole plant is used externally for treating fractures, wounds, mastitis, and snake bites.
  • Other Uses: The leaves act as a diuretic, emollient, refrigerant, styptic, and vulnerary, and are used to treat inflammation of the intestines and bladder. They are also applied externally as a poultice on wounds and skin diseases​​​​.
