Kalamitmit is a twining, herbaceous, more or less hairy vine, with slender stems. Leaves are oblong to oblong-ovate, 8 to 12 centimeters long, pointed at the tip and heart-shaped at the base. Inflorescence bears many flowers, and is borne in the axils of the leaves. Sepals are about 6 millimeters long. Corolla is white or yellow, tubular and funnel-shaped, about 3 centimeters long; limb is about 2.5 centimeters in diameter. Capsule is ovoid, smooth, about 1 centimeter long. Seeds are covered with spreading, black or brown hairs.

- Throughout the Philippines, in thickets at medium altitudes.
- Pantropic.

- Plant considered deobstruent, diuretic and alterative.

Parts used
Root, leaves, seeds.


- Young leaves may be mixed with other vegetables and eaten.
- Pounded leaves used as poultice for burns and scalds.
- In the Moluccas, poultice of leaves used for sores. Also leaves used as emollient for abscesses and ulcers.
- Decoction of plant used as deobstruent, diuretic and alterative; useful for rheumatism, headaches and neuralgia. Also used for dropping into the ears in cases of auricular ulcers and abscesses.
- In epilepsy, powder of leaves is sniffed up.
- Paste or powder of root, mixed with Java flour and water, applied to swellings.
- In Bengal, seeds are soaked in water to yield a mucilage and used as an aperient or as alterative for cutaneous diseases.

Phenolic Compounds / Allelochemical:
Study investigated the potential allelochemicals of the invasive plant Merremia umbellata subsp. orientalis. Results yielded eight phenolic compounds, including a salicylic acid (SA)-derived new natural product, SA 2-O- β-D-(3',6'-dicaffeoyl)-glucopyranoside. Compound 2 showed remarkable inhibition of seed germination of Arabidopsis. (1)
Cytotoxic / Antioxidant:
Study compared the antioxidant potential and cytotoxic activity of Ipomoea pes-caprae and Merremia umbellata. Merremia umbellata showed less cytotoxic activity (less than 75%) compared to Ipomoea pes-caprae (more than 80%). Ipomoea pes caprae showed marginally better antioxidant properties compared to Merremia umbellata. (5)
