What are the morphological characteristics of this plant?
Crinum latifolium has large, lanceolate, bright green leaves that grow in a basal rosette from a thick, fleshy bulb. The foliage is characterized by prominent parallel venation and a smooth, somewhat leathery texture. From the center of this leaf cluster, a long, leafless scape emerges to support a cluster of fragrant, white, trumpet-shaped flowers. These blossoms feature six tepals and prominent stamens that radiate from the center. The entire plant is anchored by a substantial bulbous root system that stores nutrients for growth.
What is the geographical distribution of this plant?
This plant is native to the tropical regions of West Africa, specifically ranging from Senegal to Nigeria. It thrives primarily in coastal areas and moist forest environments where humidity is high. Within these habitats, the species is often found in sandy soils near riverbanks or swampy lowlands. Its distribution is closely tied to the warm, wet climate characteristic of the Guinean forest-savanna mosaic. This specific environmental requirement limits its natural presence to these particular equatorial belts.
How is this plant cultivated?
This plant requires well-draining, fertile soil and consistent moisture to thrive in warm, tropical or subtropical climates.
It prefers being grown in partial shade to protect its broad leaves from intense midday sun. Regular fertilization during the growing season supports the development of its large, fleshy bulbs and lush foliage. Because it is susceptible to root rot, ensuring proper drainage is essential during the cultivation process.
Frequent watering is necessary, especially during hot periods, to prevent the plant from wilting.
What parts of this plant are used medicinally?
This plant utilizes its bulbs, leaves, and pollen for various medicinal applications in traditional healing practices. The large bulbs contain concentrated bioactive compounds often used to treat inflammatory conditions or skin ailments. Extracts from the long, strap-like leaves are frequently applied topically or processed to manage specific internal health issues. Additionally, the pollen serves as a specialized component in certain medicinal preparations. These diverse parts allow for a wide range of therapeutic uses depending on the specific ailment being addressed.
According to a study published by "Fitoterapia", the bulbs of Crinum latifolium were used to produce a 95% EtOH extract for the isolation of five alkaloids. These compounds, including four novel alkaloids (1, 2, 3, and 4) and one known alkaloid (5), were evaluated for cytotoxic activity against seven lung cancer cell lines. The alkaloids 1-5 exhibited potent cytotoxicity with IC50 values < 30 nM. Alkaloids 3 and 4 demonstrated significant antimicrobial activity with IC50 values < 0.50 mM and showed antioxidant activity in ABTS and DPPH tests. Furthermore, alkaloids 1-5 exhibited inhibition of Cox-1 > 64% and Cox-2 > 90%.

According to a study published by "International immunopharmacology", hot aqueous extract of Crinum latifolium is used in Vietnamese and Chinese traditional medicine because of its antitumoer activity. The genus Crinum is thought to possess antiviral and immunostimuative properties. In this study, the immunomodulatory property of C. latifolium (L.) extracts was investigated in human peripheral blood mononuclear cells. Extracts of C. latifolium (L.) slightly enhance neopterin production in unstimuated peripheral mononuclear cells. An effective reduction of neopterin formation was observed in cells stimulated with concanavalin A (Con A), phytohemagglutinin (PHA), or interferon-gamma (IFN-gamma). C. latifolium (L.) extracts seemed to be more effective in reducing neopterin formation in stimulated cells.

According to a study published by "BMC complementary medicine and therapies", Crinum latifolium is used in Southeast Asian traditional medicine to alleviate symptoms of benign prostatic hyperplasia. The ethanolic extract of Crinum latifolium leaves exhibits antiproliferative activity against TGF-beta-promoted human prostate stromal cells known as WPMY-1. Two major alkaloids, lycorine (1) and 6alpha-hydroxybuphanidrine (2), were isolated from the ethanolic leaf extract. The extract contained 0.279 +/- 0.003% of lycorine (1) and 0.232 +/- 0.004% of 6alpha-hydroxybuphanidrine (2). This crude extract proved to be more potent than either alkaloid (1) or (2) alone against TGF-beta-treated WPMY-1 cell proliferation. The greatest synergistic effect between the two alkaloids was achieved at a 1:1 ratio.
