How does Typhonium flagelliforme work as an anticancer agent?

Typhonium flagelliforme contains ribosome-inactivating proteins (RIPs), which are the primary compounds studied for anticancer activity. These proteins function by inhibiting protein synthesis in cells. In vitro research suggests these compounds may induce apoptosis (programmed cell death) and inhibit tumor cell proliferation, though human clinical trials are currently lacking (Evidence Level: C).

Can I take Typhonium flagelliforme with chemotherapy drugs?

There is insufficient clinical data to confirm the safety of combining Typhonium flagelliforme with chemotherapy drugs. Because the herb contains biologically active compounds that may affect the immune system and liver enzymes, it could theoretically interfere with the metabolism of certain oncology medications. Patients must consult an oncologist before use to avoid potential adverse interactions.

Is Typhonium flagelliforme safe during pregnancy?

No, Typhonium flagelliforme is considered unsafe during pregnancy and breastfeeding. The plant contains potent active compounds and uterine stimulants that may pose a risk of miscarriage or harm to fetal development. Safety assessments indicate it should be strictly avoided by pregnant women or those planning to conceive.

What is the recommended dosage for Typhonium flagelliforme?

There is no established standard dosage for Typhonium flagelliforme due to a lack of clinical trials. In traditional practice and commercial supplements, it is typically administered as a tuber extract. Because the raw corm can be toxic and the herb is potent, usage should only occur under the strict supervision of a qualified medical professional.

What are the side effects of Typhonium flagelliforme?

Reported side effects generally include mild nausea and digestive discomfort. A significant safety concern involves the handling or ingestion of the raw corm, which contains calcium oxalate crystals that can cause severe irritation to the mouth, throat, and skin. Proper processing is required to mitigate this irritation.

Résumé

Typhonium flagelliforme, known as 'rodent tuber', is a medicinal plant used traditionally in Malaysia for the treatment of cancer [PMID: 11351365, 20673794, 20569984].

Contexte

Typhonium flagelliforme (Lodd.) Blume is a tropical plant of the Araceae family indigenous to Malaysia [PMID: 18436400, 20673794, 20569984].

Usages traditionnels

It is traditionally used by ethnic populations in Malaysia as a remedy for various cancer diseases, including leukemia [PMID: 39358218, 11351365, 20673794, 20569984].

Composés actifs

Identified compounds include stigmasterol and 7α-hydroxyl stigmasterol [PMID: 39358218], beta-sitosterol, beta-daucosterol, coniferin, and 1-O-beta-glucopyranosyl-2-[(2-hydroxyloctadecanoyl) amido]-4,8-octadecadiene-1,3-diol [PMID: 15272778]. Other constituents include pheophorbide-a, pheophorbide-a', pyropheophorbide-a, and methyl pyropheophorbide-a [PMID: 19833183], as well as tocopherols [PMID: 39519912, 40806278], high concentrations of arginine and tryptophan [PMID: 11351365], and various fatty acid methyl esters [PMID: 11483390].

Mécanisme d'action

The plant may induce apoptosis via the suppression of survivin and activation of caspase-9 and caspase-3 [PMID: 33342788], or through cytochrome c release and PARP cleavage [PMID: 20673794]. It has been shown to cause cell cycle arrest at the G2/M phase [PMID: 40054700] or G0/G1 phase [PMID: 20673794]. In silico studies suggest compounds may act as competitive regulators of the Farsenoid X receptor (FXR) [PMID: 39358218] or inhibit NEK7 [PMID: 41003845] and mutated K-Ras [PMID: 25309590].

Preuves cliniques

Preuve DCancer (General/Various cell lines)

In vitro extracts (methanolic, dichloromethane, and hexane) demonstrated antiproliferative activity and induced apoptosis in various cancer cell lines [PMID: 40054700, 18436400, 11351365].

Preuve DLeukemia

Dichloromethane tuber extracts inhibited the growth of murine leukemia WEHI-3 cells in vitro and decreased immature granulocytes and monocytes in the peripheral blood of BALB/c leukemia mice in vivo [PMID: 20569984, 20673794, 21785623].

Preuve DBreast Cancer

Tuber extract induced apoptosis in breast cancer stem cells (CD44+ CD24-/low) by suppressing survivin [PMID: 33342788] and showed antiproliferative activity against HS578T cell lines [PMID: 19833183].

Preuve DLung Cancer

Hexane and dichloromethane extracts inhibited the growth of NCI-H23 non-small cell lung carcinoma cell lines in vitro [PMID: 18436400].

Preuve DImmunosuppression

Ethanolic extract reduced the immunosuppressive effects of cyclophosphamide in rats, increasing macrophage phagocytic activity and CD8+ T cell proliferation [PMID: 25613330].

Sécurité et effets indésirables

A combination formulation containing T. flagelliforme ethanolic extract, Piper crocatum, and Phyllanthus niruri was found safe in Sprague-Dawley rats up to 5000 mg/kg b.w. in acute tests, and showed no adverse clinical or histopathological effects at doses up to 90 mg/kg b.w./day for 90 days [PMID: 36636256].

Synthèse des preuves

The current evidence is primarily based on in vitro cell line studies, in silico modeling, and animal models (rats/mice). There are no human clinical trials provided; therefore, the overall strength of evidence for clinical efficacy is low (Level D).
