This plant is native to the tropical and subtropical regions of Central and South America, ranging from southern Mexico through the Caribbean to parts of Brazil. It thrives primarily in moist, shaded environments such as rainforest edges and secondary forests. Within these habitats, the climbing vine spreads across various elevations depending on the specific microclimate. Its presence is most consistent in humid lowland areas where rainfall is frequent and temperature fluctuations are minimal. This wide distribution allows the species to occupy diverse ecological niches across the Neotropics.
How is this plant cultivated?
This plant requires consistently moist, well-draining soil and partial shade to thrive in tropical or subtropical climates.
It is a vigorous climbing vine that benefits from regular fertilization to support its rapid growth.

At a dose of 100 microM, this compound completely inhibited whole blood chemiluinescence in response to the activators PMA and zymosan. In isolated inflammatory rat leukocytes, it inhibited leukotriene B4 production with an IC50 of 15 microM and 5-HETE production with an IC50 of 30 microM. The formation of thromboxane B2 was not inhibited within the concentration range of 10 to 200 microM. Additionally, the formation of platelet activating factor (PAF) was suppressed with an IC50 of less than 20 microM.
The primary pharmacological activities of this plant are shown in the list below.
- anti-inflammatory
- anti-ulcerogenic

What medicinal compounds this plant contains?
This plant contains an alkaloidal fraction and scandenolide as its primary medicinal compounds. These chemical components are significant for their potential therapeutic applications in pharmacological research. Scientists study the specific properties of the alkaloidal fraction to understand its biological activity. Furthermore, the presence of scandenolide contributes to the overall medicinal profile of Mikania cordata. These substances work together to define the plant's unique chemical signature.
As discussed in a study, Mikania cordata contains an alkaloidal fraction that demonstrates anti-ulcerogenic effects. In experimental groups, the administration of 50 mg kg(-1) of this alkaloidal fraction significantly increased pH values in the stomach to 3.09 +/- 0.0429 compared to 2.07 +/- 0.0339 and in the duodenum to 6.79 +/- 0.1162 compared to 6.19 +/- 0.1273. The ulcer index for the stomach in the alkaloidal-administered group was 0.268 +/- 0.0346, which was lower than the 0.691 +/- 0.0184 seen in the diclofenac group. Similarly, the duodenal ulcer index was 0.050 +/- 0.0129 compared to 0.0933 +/- 0.0138. Histological grading showed 0 lesions in the alkaloidal-administered group compared to 5 lesions in the diclofenac-only group.

According to a study published by "Planta medica", the methanolic fraction of Mikania cordata root extract was investigated for its potential ulceroprotective activity. Oral administration of the extract at doses of 50, 100, or 150 mg/kg significantly prevented gastric ulcers induced by water immersion stress. The extract also dose-dependently inhibited ulcers induced by ethanol, aspirin, and phenylbutazone. The ED50 values for the four ulcer models were 95.1, 109.7, 125.5, and 136.2 mg/kg, respectively. While doses of 100 or 150 mg/kg did not alter gastric juice volume, acidity, or peptic activity, the extract significantly promoted gastric mucus secretion. These results indicate that Mikania cordata possesses antiulcer activity by improving gastric cytoprotection.
