Cabello de angel is a slender, twining, smooth vine growing 4 to 6 meters or more. Leaves are ovate, 4 to 7 centimeters long, dark green, and pinnately divided into numerous, linear, distant segments. Cymes are axillary, containing few, erect flowers; the peduncles are 4 to 9 millimeters long. Corolla is deep red and salver shaped; the tube about 2 centimeters long and slightly enlarged upward; the limb spreading, 1.5 to 2 centimeters in diameter, and distinctly 5-lobed. Fruit is a capsule, ovoid, 7 to 8 millimeters long, with smooth, black seeds.

- Found in Ilocos Norte, Bontoc, Nueva Viscaya, La Union, Pampanga, Bulacan, Rizal, Bataan, Laguna, Camarines, Albay, and Sorsogon Provinces in Luzon; and in Panay, Negros, Cebu and Mindanao, in thickets at low and medium altitudes.
- Cultivated in urban gardens.
- Now thoroughly naturalized.
- Native of tropical America.
- Now pantropic.

- Leaves are reported to contain small amounts of alkaloids.
- Traces of hydrocyanic acid are also present in roots, stems and flowers.
- Resin glycoside (convolvulin) fraction of the seeds provided five new glycosidic acids, quamoclinic acids B, C, D, E, and F, along with six organic acids, isobutyric, 2S-methylbutyric, tiglic, 2R,3R-nilic, 7S-hydroxydecanoic, and 7S-hydroxydodecanoic acids. (See studies below) (3)
- Phytochemical analysis of whole plant yielded alkaloids, carbohydrates, saponns, phytosterols, phenolic compounds, tannins flavonoids, proteins, amino acids, terpenoids, gums and mucilages. (see study below) (8)
- Proximate analysis of whole plant yielded 9.68% total ash, 3.57% acid insoluble ash, 2.95% water soluble ash, 3.49% sulphated ash, 12.92% alcohol soluble extractive value, 9.45% water soluble extractive values, 5.41% ether soluble extractive value and 5.25% moisture content. (9)

- Roots are considered an effective sternutatory.
- Hindus consider the plant to have cooling properties.

- In the Philippines, leaves are used as poultices for bleeding hemorrhoids.
- Crushed leaves used for carbuncles.
- Seeds reportedly used as laxative by the Sino-Annamites.
- In Queensland, used as purgative, as snuff, and for snake bites.
- In India, powdered roots given as sternutatory; pounded leaves applied to bleeding piles.
- In Spain, powdered roots used as sternutatory; pounded leaves used for hemorrhoids, ulcers and breast pain.
- In
Brazil, aerial parts used as depurative or antibiotic.
- Kani tribe in
Kerala, apply leaf paste over the throat for splinters. (6)
- In the Antilles, roots are considered an effective sternutatory and the latex used for coryza.
- In Siddha medicine, leaves used for piles and diabetes; the leaf and stem decoction used for fever.
- In Ayurveda, leaves are used for stabilizing the gravid uterus.

New Glycosidic Acids:
Study isolated two new glycosidic acids, quamoclinic acids G and H from the glycosidic acid fraction. (2)
Glycosidic Acids: Alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction of the seeds yielded five new glycosidic acids, quamoclinic acids B, C, D, E, and F along with six organic acids.
Quamoclinic acids E and F are the first examples of heptaglycosides of glycosidic acid. (See constituents above) (3)
Anti-Diabetic: Study evaluated the anti-diabetic activity of whole plant of I. quamoclit against STZ-induced diabetic rats. A hydroalcoholic extract of whole plant showed significant reduction in blood glucose.(see constituents above) (8)
Antiproliferative: Study evaluated the anti-proliferative effect of various extracts of Ipomoea quamoclit leaves against MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma), CNE-1 (nasopharyngeal carcinoma, HT-29 (colorectal adenocarcinoma) and 3T3 (normal mouse fibroblast) cell lines. The methanol leaf extract showed the highest anti-proliferative activity against the tested cell lines. (9)
Antioxidant: Study evaluated the antioxidant activity of P. paniculata and Ipomoea quamoclit whole plants. Ipomoea quamoclit yielded total flavonoids of 49.26 (quercetin) and total phenols of 39.32 mg/g (gallic acid). Both plants exhibited significant antioxidant activity by various assays. (10)
