Botany
Mankit is a slender, branched, creeping or climbing herb growing to a height of about 4 meters, with numerous small prickles on the stems. Leaves are 4 to 7 in a whorl around a central stem, ovate, 3 to 5 centimeters long, pointed at the tip, heart-shaped at the base, and rough above, on the veins beneath, and especially on the margins, being furnished with small, white, recurved prickles. Petioles are long - about twice as long as the blade - with many sharp, recurved prickles on the angles. Flowers are minute, white or yellow, and on short, smooth stalks. Corolla-tube is thick and very short, lobes being ovate and obtuse. Fruit is rounded, 6 to 8 millimeters long, shining, and purplish black.

Distribution

Studies
COX-2 Inhibitor / Cancer Chemoprevention:
Study isolated several secondary plant metabolites from the roots of R. cordifolia and rhizomes of G. glabra. A few molecules showed potent COX-2 inhibitory activity which may serve as lead molecules for cancer chemoprevention studies. (3)
Radioprotective: Study of radioprotective potential of alcoholic extract of root of Manjistha showed a significant radiation protection (67%) as assessed by increased animal survival when R. cordifolia extract was administered intraperitoneally before radiation exposure. Results suggest the alcoholic root extract provides protection against radiation-induced lipid peroxidation, hemopoietic injury and genotoxicity. (4)
Anti-urolithiasis / Roots: Study showed a protective effect of the hydro-alcoholic extract of R. cordifolia roots against ethylene glycol-induced urolithiasis in rats. Mechanism may be through antioxidant nephroprotection and an effect on urinary concentration of stone-forming constituents. (5)
Anti-urolithiasis One of the major constituents of the roots is ruberythric acid, widely used as phytotherapy in treating urinary tract calcium containing stones.
Neuroprotective / ß-Amyloid Induced Cognitive Dysfunction: Study of animals with ß-amyloid induced cognitive dysfunction pretreated with an ethanolic extract of R. cordifolia showed significant protective effect on neurodegeneration and showed improvement in memory retention activity. The neuroprotective activity of the plant on Alzheimer's type dementia may be due to inhibition of AChE, MAO, free radical scavenging activity. (6)
Gastroprotective: Study in Wistar rats investigating the activity of R. cordifolia against experimentally induced gastric ulcer showed the chloroform fraction with significant activity at lower doses compared to the parent extract. Mechanism can be attributed to decrease gastric acid secretory activity along with strengthening of the mucosal defensive mechanism by prostaglandin synthesis and antioxidant potential. (7)
