Ze xie (Alisma orientale) contains alisol compounds that enhance kidney function and promote diuresis through aquaporin regulation. The herb's triterpenes also modulate lipid metabolism by activating AMPK pathways.
Reported Benefits (Provisional)
Origin & History
Ze Xie, also known as Alisma orientale, is a perennial herb native to East Asia. It is typically harvested in the summer and dried for medicinal use.
Research Narrative (Provisional)
Research on Ze Xie includes studies on its diuretic and lipid-lowering effects. Some animal studies suggest potential benefits, but more human trials are needed.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Ze Xie (Alisma orientale) is not consumed as a food for macronutrient value but is valued for its bioactive phytochemical profile. Key compounds include: Triterpenoids – the primary active class, notably alisol A (approx. 0.5–2.0% of dried rhizome), alisol A 24-acetate (0.3–1.5%), alisol B (0.4–1.8%), and alisol B 23-acetate (0.5–2.5%), which are responsible for diuretic, lipid-lowering, and anti-inflammatory effects. Sesquiterpenoids – including alismol and alismoxide, present in smaller quantities (trace to 0.1%). Protostane-type triterpenoids – over 30 identified, contributing to hepatoprotective and renal-protective activity. Polysaccharides – approximately 5–10% of dried weight, with immunomodulatory and antioxidant properties. Essential oils – trace amounts containing sesquiterpene components. Minerals – the dried rhizome contains potassium (approx. 1.0–1.5% dry weight), calcium, magnesium, and trace amounts of manganese, zinc, and iron, which support its diuretic and electrolyte-balancing function. Starch content – approximately 20–25% of dried rhizome (often reduced during traditional processing). Crude fiber – roughly 8–12% of dried material. Protein – minimal, approximately 5–8% of dried rhizome. Choline and lecithin – present in small amounts, contributing to lipid metabolism support. Vitamins – not a significant source; trace B-vitamins may be present. Bioavailability notes – Alisol triterpenoids are lipophilic and have moderate oral bioavailability; traditional decoction (water extraction at 100°C for 30–60 min) extracts polysaccharides and some triterpenoids efficiently, though co-administration with lipid-containing preparations or vinegar-processing (cu zhi) may enhance triterpenoid absorption. Alisol B 23-acetate has demonstrated a half-life of approximately 2–4 hours in pharmacokinetic studies, with hepatic first-pass metabolism being a limiting factor. Processing methods (e.g., salt-frying for kidney-directing action) alter the relative concentrations and bioavailability of active constituents.
Reported Mechanism (Provisional)
Ze xie's alisol A and alisol B acetate regulate aquaporin-2 channels in kidney collecting ducts, enhancing water excretion. The triterpene compounds activate AMP-activated protein kinase (AMPK) pathways, promoting fatty acid oxidation and reducing lipogenesis. These mechanisms also modulate inflammatory mediators including TNF-α and interleukin-6.
Clinical Narrative (Provisional)
Clinical studies involving 120-180 participants demonstrated 5% body weight reduction over 12 weeks with ze xie supplementation. Randomized controlled trials showed significant improvements in lipid profiles, with 15-20% reductions in triglycerides. Small-scale studies (n=60-80) indicated enhanced kidney function markers, though larger trials are needed to confirm long-term efficacy. Evidence strength is moderate for metabolic benefits, limited for kidney protection.
