What are the morphological characteristics of this plant?
Quisquaalis indica has a creeping, prostrate stem that forms dense mats and produces small, inconspicuous white flowers arranged in axillary clusters. The plant features trifoliate leaves, meaning each leaf consists of three distinct, oval-shaped leaflets with entire margins. These leaflets are typically bright green and possess a smooth texture that allows them to spread closely against the soil surface. The reproductive structures consist of tiny, globose fruits that develop from the small blossoms. This low-growing growth habit makes the species highly effective at covering ground in moist, shaded environments.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, including countries such as Thailand, Malaysia, Indonesia, and parts of India. It thrives primarily in moist, lowland environments and humid forest understories where shade is abundant. The species is frequently found in coastal areas and near riverbanks where water availability is consistent. Its distribution is closely tied to the warm, wet climates characteristic of these equatorial zones. Because it requires high humidity, its presence is limited to specific ecological niches within these geographic boundaries.
How is this plant cultivated?
This plant, commonly known as betel, thrives in tropical climates with high humidity, well-drained soil rich in organic matter, and consistent rainfall.
Cultivators typically grow it as a climbing vine by providing sturdy supports such as wooden poles or living trees. To ensure vigorous growth, the soil should maintain a slightly acidic pH level and receive partial shade to prevent leaf scorch. Regular fertilization with nitrogen-rich compost helps promote the lush, green foliage required for harvest.
Careful moisture management is essential to prevent root rot while avoiding dehydration during dry periods.
What parts of this plant are used medicinally?
This plant Quisqualis indica utilizes its flowers, fruits, seeds, and peel for various medicinal purposes. The fragrant flowers are often processed to treat skin ailments and inflammation. Its fleshy fruits can be used to address digestive issues or specific localized pains. The seeds are frequently employed in traditional remedies to manage internal discomfort. Additionally, the peel of the plant is harvested to create decoctions aimed at treating various systemic ailments.
According to a study published by "Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie", the floral extract of Quisqualis indica was used to fabricate copper nanoparticles (QCuNPs) from copper acetate. This study represents the first exploration of the potential of Q. indica for the formulation of eco-friendly copper nanoparticles. These QCuNPs exhibited significant cytotoxic potentials against B16F10 melanoma cells as determined by MTT and lactate dehydrogenase (LDH) assays. The nanoparticles induced melanoma cell death through the induction of oxidative stress, specifically through the estimation of GSH and ROS. Furthermore, QCuNPs caused the up-regulation of caspase-dependent and caspase-independent (AIF) apoptotic genes. In animal models, these nanoparticles showed potential suppression of B16F10 melanoma cell proliferation and substantial inhibition of tumor growth.
