Lirio is a lily plant, with subglobose bulbs up to 10 centimeters in diameter. Leaves are many, oblong-linear, 30 to 100 centimeters long, 5 to 8
centimeters wide. Scape is inserted on neck of the bulb,
about as long as the leaves, stout and tinged with purple. Flowers are about 10 in each umbel, fragrant, about 8 centimeters long. Perianth tube is curved, 10 to 12 centimeters long. Segments are oblong-lanceolate, 7.5 to 10 centimeters long, 2.5 to 3 centimeters wide, white but flushed with pale purple in the median part. Filaments are white. Fruit is somewhat rounded, 4 to 5 centimeters in diameter. The cultivated hybrid
forms give a variety of colors, some with white stripes running from
the center of red segments.

• Immunomodulatory: Study
showed extract of C latifolium slightly enhanced neopterin production
in unstimulated peripheral mononuclear cells with an effective reduction
of neopterin formation in stimulated cells. (1)
A novel in vitro and in vivo T-lymphocyte activating factor in Crinum
latifolium (L.) aqueous extracts. The study suggests potential use
of C. latifolium for treatment of cases of immunodeficiency as cancer, leukemia and
• Mast Cell Stabilizing:
Mast cell stabilizing effect of glucan A and phosphatidyllycorine
isolated from Crinum latifolium – Effect of glucan A and phosphatidyllycorine
from CL in vitro produced significant protection against mass cell
degranulation as well as to sensitized mast cells challenged with
a horse serum antigen. In vivo, it also provided protection against
degranulation of mast cells. Results support is use in Ayurvedic medicine
in the treatment of allergic disorders. (4)
• Benign Prostatic Hypertrophy:
A study in the International Hospital in Vietnam using extract cycles
of 21 days-on/7 days-off reported a 92.6 % benefit measured by prostate
size and clinical urologic evaluation. (5)
A monocot mannose-binding amaryllidaceae lectin from the bulbs of
CL was found to be non-toxic towards African green monkey kidney epithelial
cells and exhibited a significant antiviral potential against a strain
of vaccinia virus in vitro. (7)
A study on cold-hot aqueous extracts from Vietnamese CL showed inhibition
of carcinogenesis in rats probably due to the influence of immunomodulating
and anti-tumour plant alkaloids and other biologically active components
in the plant decoctions. (8)
• NF-kB Inhibitory Activity:
87 methanol extracts from Vietnamese oriental medicinal plants were screened for NF-kB inhibitory activity. NF-kB is an inducible and ubiquitous transcriptional factor needed for gene expression of many inflammatory mediators. Seven of the extracts, including C. latifolium showed strong to moderate inhibitory activity. (9)
• Benign Prostatic Hypertrophy / Soft Gel Formulation: Study was done of soft gel transformed from the dry glue of Crinum latifolium alkaloid for therapeutic effect in benign prostatic hypertrophy. Results concluded (1) soft gels of CL are effective for treatment of BPH, and (2) the drug is safe, with little side effects. (10)
• Antiproliferative / Prostate Tumors: Treatment of human prostate carcinoma PC3 and LNCaP cells, and benign prostate hyperplasia BPH-1 cells with water extracts of C. latifolium showed a significant dose-dependent inhibition of cell growth. The inhibition of tumor cell growth and recovery of immune functions may contribute to its beneficial effects in the treatment of prostate tumors. (12)
• Antioxidant: Crinum latifolium showed potent peroxyl-radical scavenging activity in vitro.
• Anti-Inflammatory: An aqueous extract of C. latifolium exhibited strong anti-inflammatory effect on mitogen stimulated PBMC by counteracting mitogen-induced activation of IDO enzyme activity and secretion of neopterin.
• Anthelmintic / Total Phenolic Content / Cytotoxicity: Study of a methanolic extract of Crinum latifolium leaves showed significant activity against Pheretima posthuma. Cytotoxicity testing using brine shrimp lethality test method showed positive result (LC50 15.652 µg/ml) compared to vincristine sulfate (0.839 µg/ml) as positive control. Crude methanolic extract exhibited lower amount of total phenolic content (17.50 ± 2.64 mg/ml). (14)
• Hemagglutination Activity / Lectin / Bulbs: Study evaluated the biologic activity of a lectin isolated from the bulbs of C. latifolium with carbohydrate specificity towards methyl-α-D-mannopyranoside. Study showed humagglutination activity, and was virtually non-mitogenic towards peripheral blood mononuclear cells. (16)
• Anti-Tumor Activity / Inhibition of Lymphoma Cells Proliferation: Study evaluated the CL leaf extracts on anti-tumor activity of peritoneal murine macrophages. Results showed CL extracts and alkaloid fraction inhibit the proliferation of lymphoma cells in multiple pathways. (17)
• Thrombolytic / Leaves: Study investigated the thombolytic potential of crude methanolic extract of leaves of C. latifolium. Results showed significant thrombolytic activity (p<0.001). Plant showed moderate clot lysis activity of 14.64 ± 0.540%, 18.01 ± 0.766%, 21.78 ± 1.039%, 28.43 ± 0.982%, and 33.84 ± 1.749% at 2, 4, 6, 8, and 20 mg/ml concentrations, respectively, while standard streptokinase showed 47.27 ± 1.998% clot lysis. Results suggest good thrombolytic activity of the leaves in vitro; however, in vivo thrombolytic potential s yet to be determined. (20)
Inhibitory Effect against Tube-like Formation of Human Umbilical Venous Endothelial Cells: Study of methanol extract yielded six compounds. Compound 2 was found strongly inhibitory activity while compound 6 showed modest inhibitory activity against in vitro tube-like formation of human venous endothelial cells (HUVECs) with no cytotoxicity in tumor cell lines.(see constituents above) (22)
• Antitumor / Suppression of Immune Activation Cascades in Peripheral Blood and Proliferation of Prostate Tumor Cells: Study demonstrated the potent in vivo antioxidant activity of aqueous extract of C. latifolum extract by an oxygen radical absorbance capacity (ORAC) value of 1610 ± 150 µmol Trolox equivalents/g. Study showed dose-dependent inhibitory effects of an aqueous extract on cell proliferation of highly metastatic human prostate carcinoma PC3 cells,, androgen-sensitive prostate adenocarcinoma, and benign prostatic hyperplasia BPH-1 cells. Results showed inhibition of tumor cell growth and recovery of immune functions, both important antitumor properties of C. latifolium. (23)
