These morphological features allow the plant to thrive in shaded, moist environments where it spreads via its creeping root systems.
What is the geographical distribution of this plant?
This plant is native to the Mediterranean region, spanning across parts of Southern Europe, North Africa, and Western Asia. It commonly thrives in diverse habitats such as rocky slopes, dry grasslands, and open woodlands. Populations are frequently found in regions with seasonal rainfall and well-drained soils. Its distribution is often linked to areas characterized by temperate climates and sunny exposures. This specific range allows the species to colonize various ecological niches within its native territory.
How is this plant cultivated?
This plant thrives in well-draining, humus-rich soil and requires consistent moisture alongside partial shade to prevent leaf scorch.
Gardeners should maintain a temperature range between 60 and 75 degrees Fahrenheit for optimal growth. Propagation is most effectively achieved by dividing the underground bulbils during the early spring or autumn months. Regular weeding and occasional fertilization will help maintain its dense, creeping groundcover habit.
Careful monitoring for moisture levels is essential to prevent the delicate foliage from wilting in intense heat.
What parts of this plant are used medicinally?
This plant Oxalis corniculata is utilized medicinally through the use of its aerial parts, which include the leaves and the whole plant. The entire above-ground structure is often prepared as a decoction or infusion to treat various ailments. Specifically, the leaves are frequently harvested to extract bioactive compounds for therapeutic purposes.

According to a study published by "Galen medical journal", the aerial parts of Oxalis corniculata were collected in Lahijan city, Iran, and extracted with ethanol for 24 h. The total phenolic content of this extract was 31.30±02 μg of gallic acid equivalents/mg of dry extract, while the total flavonoid content was 49.61±04 μg of quercetin as equivalents/mg of extract. Antioxidant activity was measured at the dose of 619.2 μg/μl, which decreases cancer cell viability and enhances apoptosis. In MCF-7 cells treated with the extract, real-time PCR revealed substantial increases in p53 (P<0.001), CD95 (P<0.05), and bcl-2 (P<0.05) expression. These findings suggest that Oxalis corniculata may cause apoptosis by oxidative stress in cancer cells.
