Similax Sieboldii Extract
Also known as: Smilax sieboldii Miq., S. sieboldii, Smilax sieboldii
Overview
Smilax sieboldii is a plant species belonging to the Smilax genus, known for its aerial parts and rhizomes which contain a diverse array of steroidal saponins. These saponins, including 6-oxofurostane and (iso)spirostane types, are natural secondary metabolites considered to be bioactive compounds. Extracts from Smilax sieboldii are utilized in botanical dietary supplements primarily due to this rich steroidal saponin content, which theoretically may possess pharmacological potential. The extract is chemically characterized by a complex mixture of these saponins, such as diosgenin, sarsasapogenin, tigogenin, and various laxogenin derivatives, identified through advanced analytical techniques like UHPLC-QToF-MS/MS. Current research on Smilax sieboldii is predominantly phytochemical and pharmacognostic, focusing on the identification and characterization of its chemical constituents rather than clinical efficacy or safety in humans. Consequently, there is a notable absence of high-quality clinical trials or systematic reviews evaluating its specific health benefits or risks in human populations.
Benefits
Currently, there is no direct clinical evidence, quantified outcomes from randomized controlled trials (RCTs), or meta-analyses supporting specific human health benefits of Smilax sieboldii extract. The available research is primarily focused on the phytochemical characterization of the plant, identifying its steroidal saponin content. While steroidal saponins, in general, have been associated with potential bioactivities such as anti-inflammatory, antioxidant, or hormone-modulating effects in other contexts, these are speculative for Smilax sieboldii without direct, high-quality clinical evidence. Therefore, no specific benefits, population-specific advantages, or established effect sizes can be confidently stated for Smilax sieboldii extract at this time. The research maturity level is low regarding clinical efficacy, and further rigorous studies are needed to substantiate any health claims.
How it works
The proposed mechanism of action for Smilax sieboldii extract is inferred from its rich content of steroidal saponins. These compounds, in general, are known to interact with various biological pathways. Potential mechanisms could include modulation of steroid hormone pathways, influencing inflammatory responses, or affecting cell membrane integrity. However, the specific molecular targets, precise biological pathways, and detailed interactions with human body systems for the saponins derived from Smilax sieboldii remain largely uncharacterized. There is no available data on the absorption, bioavailability, or specific molecular targets of these compounds within the human body. Further research is required to elucidate the exact mechanisms by which Smilax sieboldii extract might exert any biological effects.
Side effects
The overall safety profile of Smilax sieboldii extract is largely unknown due to a significant lack of clinical safety data and reported adverse events. There are no documented common (>5%), uncommon (1-5%), or rare (<1%) side effects associated with its consumption. Furthermore, no specific drug interactions or contraindications have been identified or documented in the available literature. Information regarding its safety for special populations, such as pregnant or breastfeeding individuals, children, or those with pre-existing medical conditions, is also entirely absent. Without comprehensive clinical studies, the potential risks and adverse reactions associated with Smilax sieboldii extract cannot be determined. Caution is strongly advised until more robust safety data become available.
Dosage
Currently, there are no established dosing guidelines for Smilax sieboldii extract. The minimum effective dose, optimal dosage ranges for any specific purpose, and the maximum safe dose have not been determined through scientific research. Information regarding timing considerations for administration, form-specific recommendations (e.g., capsule, powder, liquid), absorption factors, or required cofactors that might influence its efficacy or safety is also unavailable. Due to the complete lack of clinical data on efficacy and safety, any use of Smilax sieboldii extract would be speculative and without evidence-based dosing recommendations. Users should exercise extreme caution given the absence of established safety thresholds.

- https://pubmed.ncbi.nlm.nih.gov/37511246/ – This study by Avula et al. (2023) utilized advanced analytical techniques (UHPLC-QToF-MS/MS and molecular networking) to identify over 40 unique steroidal saponins in Smilax sieboldii. It provides a detailed phytochemical profile of the plant, aiding in botanical product authentication, but does not assess clinical efficacy or safety in humans.
- https://www.mdpi.com/1422-0067/24/14/11487 – This publication, also by Avula et al. (2023), further details the comprehensive phytochemical characterization of Smilax sieboldii. It focuses on the identification and structural elucidation of its steroidal saponins, confirming the plant's rich chemical diversity, but offers no insights into its biological activity or clinical applications.
- https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2022.924994/pdf – This source, a systematic review by Fu et al. (2022) on Chinese herbal medicine, was consulted but did not include Smilax sieboldii. Its absence indicates a lack of systematic clinical evidence or reviews specifically focusing on this ingredient within the broader context of traditional Chinese medicine.
