Aurorang-gubat is a large, smooth, perennial climber rising from stout, somewhat fleshy roots. Leaves are on long petioles, rounded in outline, and heart-shaped at the base. Lobes are 5 to 7, usually lanceolate, 5 to 15 centimeters long, often reaching nearly to the base. Flowers are 3 to 5, on a stalk in the leaf axil. Sepals are ovate, concave, and 1 centimeter long. Corolla is pink, purple, broadly bell-shaped, smooth and about 6 centimeters long. Capsules are ovoid, 1 centimeter long or less.

Note: The species is similar to the common "aurora" (Ipomoea cairica), differing only in its much larger leaves and flowers.

Paniculatin / Glycoside / Various pharmacologic Effect:
Study isolated a glycoside, paniculatin, from the tubers of Ipomoea digitata. Pharmacologic effects included elevation of blood pressure, stimulant effect on the myocardium and respiration, a vasoconstrictor and bronchoconstrictor effect, and a spasmogenic effect on the gut, and an oxytoxic activity. (2)
Phytochemicals / Secondary Products / Antibacterial: Study isolated B-sitosterol, t-cinnamic acid, an unknown coumarin, a lignan-type resin glycoside from the tuberous roots of Ipomoea digitata. One of the compounds showed significant antibacterial activity against Pseudomonas aeruginosa and E coli. (3)
Tablet Formulation / Anti-Diabetic: Study of antidiabetic activity of tablet formulation of root extract showed statistically significant anti-diabetic activity and suggests promise for future research. (4)
Antihypertensive / Cardiovascular Benefits / Hypolipidemic: Tuber powder was evaluated for antihypertensive potential and lipid effect in a single blinded, placebo controlled study. Results showed decrease in systolic, diastolic and mean blood pressure, increased fibrinolytic activity and total antioxidant status with a significant reduction in total cholesterol, LDL and atherogenic index. (7)
Resin Glycosides: A jalapin fraction yielded a new resin glycoside, digitatajalapin 1, with three known resin glycosides. (9)
Antioxidant / Roots: Study of a methanol extract of root of I. digitata showed good antioxidant activity using DPPH, superoxide anion scavenging and iron chelating assays. (12)
Antidiabetic / Tubers: Study evaluated the hypoglycemic activity of Ipomoea digitata tuber extract in STZ-induced diabetic rats. Results showed considerable hypoglycemic activity, which may be due to the presence of active principles flavonoids and ß-sitosterol. (14)
Antibacterial / Roots: Study of tuberous roots yielded β-sitosterol,t-cinnamic acid [undecyl(E) -3-(4- hydroxyphenyl)-2-propenoate], an unknown coumarin and a lignan type resin glycoside from the tuberous roots of Ipomoea digitata. One of the compounds exhibited significant antibacterial activity against Pseudomonas aeruginosa and E. coli. (15)
Pharmaceutical Gum / Seeds: Study showed Ipomoea digitata seed gum and its graft copolymer with polyacrylamide has the potential to be used as a pharmaceutical gum. The seed gum has structure and properties similar to guargum and locust bean gums -- gums of pharmaceutical importance. (17)
Enhancement of Spermatogenesis / Roots: Study evaluated the potential of ID on reproductive status of neem oil-induced infertility in male albino rats. Results showed significant increase in sperm density and sperm motility (p,0.01) along with increase in testis and epididymis weight. The presence of ß-sitosterol in the root of ID possibly enhances the process of spermatogenesis as evidenced by histo- morphological studies. Results suggest a potential candidate for the management of male infertility. (18)
Cardiovascular benefits Hypolipidemic / Antihypertensive / Antioxidant / Tubers: Single blinded, placebo controlled study evaluated Ipomoea digitata tuber powder for antiphypertensive potential and effects on lipid profile, fibrinolytic activity and total antioxidant status in patients with stage 1 hypertension. Results showed significant (p,0.001) decrease in systolic, diastolic, and mean blood pressure, increased fibrinolytic activity and antioxidant status with a significant reduction (p,0.05) in total and LDL cholesterol and atherogenic index. (20)
Galactagogue / Lactovedic: Study evaluated the galactagogue activity of Lactovedic, an ayurvedic polyherbal formulation containing I. digitata (Vidarikand), along with Jivanti, Shatvari, Yashtimadhu and Shatapushpa. Study showed an increase in serum prolactin, protein content and glycogen of mammary gland. Significant increase in milk secretion in ducts as shown in transverse section of lactovedic treated groups' mammary gland. (21)
