Leaves are oval, 4 to 7 cm long and pointed at both ends. The spathes are 1 to 3 together, green, funnel-shaped, compressed, about 1.5 cm long and wide.

In China, used as diuretic, febrifuge and anti-inflammatory.
In Africa and India, leaves and stems cooked as vegetables.
In Southern Africa, used to combat infertility.
In Bangladesh , used for otitis media, suppurative sores, snakebites, swelling and burns. Also used for conjunctivitis, cataracts, night blindness, pain (headaches and toothaches), skin diseases (eczema, abscesses, acne, scabies, warts), respiratory tract disorders.
• Mastitis: External application of poultice of stems of Wattakaka volubilis and leaves of Commelina benghalensis ovber the affected udder.
• Grazing feed for goats with its high moisture and protein content; in Africa and India, used as feed for livestock.
• Carotenoid Composition: In a study to determine the carotenoid compositionn of green leafy vegetable, Chenopodium album, C benghalensis and Solanum nigrum were found to contain higher levels of both lutein and beta carotene.
• Antibacterial: Studies have shown antibacterial activity agaiinst Pseudomonas, Staphylococcus, E coli and B subtilis and supports its use in formulations for ethnoveterianry use for mastitis. Among crude extracts of C. benghalensis, the diethyl etheric extract was highly active against all the 10 bacteria species tested. The results offer scientific basis for the traditional use of the plant against infection by burns and wounds. In a study evaluating whole and dried plant extracts for antimicrobial activity, dried plant material yielded greater amounts of extractives. The ethanol extracts were superior to the aqueous extracts. The ethanolic extracts showed activity against C albicans, E coli, S aureus comparable to nystatin and gentamicin.
• Analgesic: Study showed C benghalensis possesses significant analgesic action probably through inhibition of prostaglandin synthesis, antioxidant activity and a central analgesic mechanism. Results provide a scientific basis for it folkloric use for pain treatment.
• Anti-Cancer: Study showed the methanolic extract of CB contains bioactive compounds that may be beneficial in the treatment of malignant growths, probably through an antineoplastic activity consequent to dysregulated expression of apoptosis-responsive genes.
• Antiproliferative / Anti-Lymphoma: Study showed C. benghalensis has anti-proliferation properties against Wil-2NS lymphoma cells.
