Arisaema Erubescens Extract
Also known as: Arisaema Erubescens, Arisaematis Rhizome, Arisaema erubescens (Wall.) Schott, Arisaema erubescens
Overview
Arisaema erubescens extract is derived from the dried roots and rhizomes of the plant, traditionally used in Traditional Chinese Medicine (TCM) for thousands of years. It is classified as a toxic herbal remedy, primarily used to address conditions such as phlegm retention, swelling, pain, and certain neurological disorders. The extract contains bioactive compounds but also toxic constituents like calcium oxalate crystals and lectins, which can cause mucosal irritation and nephrotoxicity. Processing is often employed to mitigate its inherent toxicity. Modern research has explored its potential anti-inflammatory, anti-convulsant, and anti-cancer properties, particularly in preclinical models. However, high-quality clinical trials are limited, and significant safety concerns remain due to its toxic profile.
Benefits
Preclinical studies and traditional use suggest potential anti-inflammatory, anti-convulsant, and anti-cancer properties. For instance, aqueous extracts have demonstrated anticonvulsant effects in animal models, indicating a possible role in neurological conditions. In TCM, it is used as an adjunct for neurological symptoms and phlegm-related disorders. However, there is a notable lack of robust clinical evidence, such as high-quality randomized controlled trials (RCTs), to definitively quantify these benefits in humans. The strength of evidence for these benefits is currently low, relying mostly on traditional claims and preliminary animal studies, with no statistically significant clinical data available to support widespread use.
How it works
The mechanism of action for Arisaema erubescens extract is thought to involve its bioactive compounds interacting with various biological pathways. Its potential anti-inflammatory effects may stem from modulating inflammatory mediators. The observed anticonvulsant activity in animal models suggests an influence on neurotransmission. Additionally, some compounds may exert cytotoxic effects on cancer cells. Conversely, the toxic components, primarily calcium oxalate crystals, cause irritation and nephrotoxicity by directly damaging mucous membranes and renal tubular cells. Processing methods aim to reduce toxicity by altering the chemical composition, specifically by decreasing irritant proteins and calcium oxalate content, thereby mitigating adverse interactions with body systems. Absorption and bioavailability data are limited.
Side effects
The safety profile of Arisaema erubescens is a significant concern due to its strong irritant and toxic properties. Common side effects include severe mucosal irritation in the mouth, throat, and gastrointestinal tract. More serious adverse effects include nephrotoxicity, evidenced by increased blood urea nitrogen and histopathological changes in renal tissue observed in animal studies, indicating potential kidney damage. While processing can reduce toxicity, it does not eliminate it entirely. Drug interactions are not well-studied, but caution is advised given its toxicity and potential impact on renal function. It is contraindicated in individuals with pre-existing renal impairment or mucosal lesions. Safety data for special populations, such as pregnant women and children, are absent, making its use in these groups highly inadvisable. Systemic toxicity is a potential risk with improper use.
Dosage
There is no standardized dosing established through clinical trials for Arisaema erubescens extract. Traditional use exclusively involves processed forms of the rhizome to mitigate its inherent toxicity; raw extracts are strongly discouraged due to severe adverse effects. The optimal dose for any potential therapeutic effect is unknown, as toxicity severely limits the permissible dosage. Timing and formulation are typically dictated by traditional preparation methods, where it is often combined with other herbs in complex formulations rather than used as a standalone supplement. Information regarding absorption factors, bioavailability, and required cofactors for efficacy or safety is not well characterized in scientific literature.
FAQs
Is Arisaema erubescens extract safe?
No, it carries significant toxicity risks, including severe mucosal irritation and potential kidney damage. Only professionally processed forms should be considered, and only under strict medical supervision.
What conditions can it treat?
Traditionally used for phlegm-related disorders, pain, and neurological symptoms. However, modern scientific evidence is insufficient to recommend it for any specific clinical condition.
How quickly do effects appear?
Due to a lack of human clinical trials, the onset of effects is unknown. Its use is not recommended without professional guidance.
Can it be used alone?
Typically, it is used as part of multi-herb formulations in Traditional Chinese Medicine, not as a standalone supplement, due to its toxicity and complex traditional preparation.
Is it approved by regulatory agencies?
No, it is not approved as a dietary supplement or drug in most Western countries due to significant toxicity concerns and insufficient evidence of safety and efficacy.

While it found some symptom improvement with herbal add-ons, it did not specifically analyze Arisaema erubescens extract, thus providing no direct clinical efficacy data for this particular ingredient.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10289099/ – This metabolomics and network analysis study investigated the nephrotoxicity of Arisaematis Rhizome (Arisaema erubescens). It demonstrated that processing significantly reduces nephrotoxicity by altering toxic components, whereas the raw extract induced renal damage in animal models, highlighting critical safety concerns and the importance of traditional processing methods.
