What are the morphological characteristics of this plant?
Hydrolea zeylanica has opposite, simple leaves that are typically ovate or elliptical in shape with entire or slightly serrated margins and acute tips. The stems are woody and often exhibit a sprawling or climbing growth habit depending on the specific environment. Small, inconspicuous flowers are arranged in terminal cymes and possess a characteristic structure typical of the Hydroleaceae family. The fruit develops into a small, fleshy drupe that facilitates seed dispersal. These morphological features collectively allow the plant to thrive in its native wetland or riparian habitats.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of South and Southeast Asia, specifically occurring in countries such as India, Sri Lanka, and parts of the Malay Archipelago. Its distribution is closely tied to humid, lowland environments where seasonal rainfall is abundant. Many populations are found near freshwater sources like riverbanks, marshes, and coastal wetlands. The species thrives in these warm, moist habitats that characterize the Indo-Malayan realm. Consequently, its presence is most concentrated in areas with high humidity and consistent tropical temperatures.
How is this plant cultivated?
This plant requires constant saturation in shallow water or very moist, boggy soil to thrive in its natural aquatic habitat.
It should be cultivated in a location that receives full sun to partial shade to ensure optimal growth. Because it is a semi-aquatic species, gardeners often grow it in water features, lined ponds, or specialized bog containers. Maintaining consistent moisture levels is crucial to prevent the foliage from wilting or drying out.
Regular pruning can help manage its spread and encourage more prolific flowering during the growing season.
What parts of this plant are used medicinally?
This plant utilizes its leaves for various medicinal purposes in traditional healing practices. These leaves are often crushed or decocted to treat skin ailments and inflammatory conditions. Some practitioners apply the leaf paste topically to soothe wounds or infections. Additionally, the plant extracts can be used to manage digestive issues when prepared correctly. This specific part of the herb contains bioactive compounds that contribute to its therapeutic effects.
According to a study published by "Heliyon", the green and leafy vegetables of Hydrolea zeylanica are used in diet as a rich source of nutrition and dietary fibers to reduce malnutrition and control blood sugar levels to treat diabetes related vascular complications. The hydroalcohol extracted fraction of leaves, known as HHZ, was administered orally at doses of 300 and 400 mg/kg b.w. for 4 weeks in experimental rats. The HHZ-400 dose significantly (p < 0.001) improved learning and memory impairment while reducing serum glucose and elevating insulin levels. This leaf extract also significantly (p < 0.001) improved oxidative markers including MDA, SOD, CAT, and GSH, as well as proinflammatory markers TNF-α, IL-6, and hs-CRP. These medicinal effects are supported by the presence of flavonoids such as quercetin, caffeic acid, rutin, gallic acid, and ferulic acid in the plant.

What are the pharmacological activities of Hydrolea zeylanica?
This plant has anti-inflammatory, antidiabetic, antioxidant, and free radical scavenging pharmacological activities. Research indicates that its bioactive compounds can effectively mitigate oxidative stress within biological systems. These properties allow the plant to neutralize harmful molecules through potent free radical scavenging mechanisms. Furthermore, its ability to regulate glucose levels provides significant therapeutic potential for managing antidiabetic conditions. The systemic reduction of inflammation also highlights its medicinal importance in treating various inflammatory disorders.
According to a study published by "Cellular signalling", network pharmacology analysis was conducted on 32 bioactive components of Hydrolea zeylanica to explore its antidiaabetic mechanisms. This analysis showed a core relationship between 13 selected compounds and 194 key target genes related to insulin resistance, type II diabetes mellitus, and insulin signaling pathways. When HZH was administered at doses of 300 and 400 mg/kg, it was used to examine GLUTs expression and inflammatory cytokines in T2DM rats. Specifically, HZH-400 significantly restored glucose homeostasis and inflammatory markers in these rats. The treatment also altered GLUT2 and GLUT4 expression in the liver and skeletal muscle to normal levels. The bioactive compounds of HZH were found to control blood sugar levels by modulating insulin resistance and glucose homeostasis to improve glucose uptake and insulin production.
The primary pharmacological activities of this plant are shown in the list below.
