Alisma Rhizome Extract
Also known as: Alisma Rhizome, Chinese water plantain, Zexie, Alisma, Alisma tuberosa, Alisma orientale
Overview
Alisma Rhizome is derived from the rhizome of *Alisma orientale*, a perennial aquatic plant revered in Traditional Chinese Medicine (TCM) and Korean Medicine. Recognized for its diuretic, hypolipidemic, and anti-inflammatory properties, Alisma is comprised of bioactive compounds including triterpenoids and sesquiterpenoids. The extract serves various traditional medicinal purposes, particularly in managing conditions associated with metabolic syndrome. Current research, although moderate in its robustness, largely focuses on findings from animal models, revealing its potential in addressing symptoms like elevated lipid levels. However, the variability in evidence quality necessitates further rigorous clinical trials to substantiate its efficacy and safety in human populations.
Benefits
Alisma Rhizome Extract exhibits several potential health benefits, particularly in lipid regulation; studies demonstrate it may help lower triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and uric acid levels, which are crucial for individuals with metabolic syndrome. Preclinical evidence also indicates its anti-inflammatory and antioxidant effects that contribute to liver protection. However, because human studies are lacking, the actual effect sizes remain undefined, emphasizing the importance of interpreting animal study findings with caution. Thus, while promising, these benefits need further validation in controlled human trials to establish definitive efficacy.
How it works
The mechanism of action of Alisma Rhizome Extract primarily involves the inhibition of energy and amino acid metabolism, along with the modulation of bile acid secretion. This extract appears to impact lipid metabolism and hepatic function due to its active components, although the exact molecular pathways and targets remain under investigation. Ongoing research into its bioavailability and absorption is essential for a full understanding of how it interacts with bodily systems.
Side effects
The safety profile of Alisma Rhizome Extract is considered largely favorable based on its traditional use; however, formal safety data in human subjects is still inadequate. Specific common side effects are not well-documented, and to date, there have been no reports of uncommon or rare adverse effects. Drug interactions, especially with diuretics or other medications influencing liver function, are still considered speculative, as no official contraindications have been determined. Caution is recommended for special populations, particularly pregnant or lactating women, due to the scarcity of safety data in these groups.
Dosage
Dosage recommendations for Alisma Rhizome Extract are primarily derived from animal studies due to the lack of clinical evidence in humans. Optimal dosages from animal research suggest a range of 0.75 to 1.50 g/kg/day. The no-observed-adverse-effect level (NOAEL) identified in toxicity studies in rats exceeds 2,000 mg/kg/day, indicating a potential upper safety limit. Specific guidelines on timing and formulation are currently undefined, necessitating additional research to clarify human dosage recommendations. Moreover, advancements in extraction methods (e.g., aqueous versus methanolic) may influence the bioavailability of the extract, warranting further exploration.
FAQs
