**Also Known As:** 6,7-dihydroxycoumarin, Cichoriin aglycone, Aesculin aglycone, 6,7-dihydroxy-2H-chromen-2-one, Qinpi active compound, Esculetin, 2H-1-Benzopyran-2-one,6,7-dihydroxy

## Overview

Aesculetin is a coumarin compound that exhibits antioxidant and [anti-inflammatory](/ingredients/condition/inflammation) properties through its hydroxyl group-mediated [free radical scaveng](/ingredients/condition/antioxidant)ing mechanisms. This bioactive compound demonstrates [hepatoprotective](/ingredients/condition/detox) effects by enhancing catalase (CAT) and superoxide dismutase (SOD) enzyme activity.

## Health Benefits

• Antioxidant activity through hydroxyl group-mediated [free radical scaveng](/ingredients/condition/antioxidant)ing (preclinical evidence only)
• [Anti-inflammatory](/ingredients/condition/inflammation) effects via reduction of inflammatory markers (animal/in vitro models)
• [Hepatoprotective](/ingredients/condition/detox) properties by boosting CAT and SOD enzymes at 100-500 mg/kg doses (animal studies)
• Anti-diabetic potential through glycemic index modulation (preclinical models)
• Anti-cancer activity via apoptosis modulation and gene expression (in vitro studies)

## Mechanism of Action

Aesculetin exerts its antioxidant effects through hydroxyl group-mediated neutralization of free radicals and [reactive oxygen species](/ingredients/condition/antioxidant). The compound enhances hepatic antioxidant defense by upregulating catalase (CAT) and superoxide dismutase (SOD) enzymes. Its [anti-inflammatory](/ingredients/condition/inflammation) activity involves the reduction of pro-inflammatory markers, though specific pathway inhibition requires further elucidation.

## Clinical Summary

Current evidence for aesculetin is limited to preclinical studies including animal models and in vitro research. [Hepatoprotective](/ingredients/condition/detox) effects have been demonstrated in animal studies using doses of 100-500 mg/kg, showing significant increases in [antioxidant](/ingredients/condition/antioxidant) enzyme activity. Antioxidant and [anti-inflammatory](/ingredients/condition/inflammation) properties have been observed in laboratory and animal models, but no human clinical trials have been conducted. The therapeutic potential remains promising but requires human studies to establish safety and efficacy profiles.

## Nutritional Profile

Aesculetin (6,7-dihydroxycoumarin) is a pure phenolic compound (coumarin derivative), not a whole food ingredient, and therefore contains no macronutrients (zero protein, fat, carbohydrates, or dietary fiber) and no conventional micronutrients (vitamins or minerals). Its profile is defined entirely by its bioactive chemistry: Molecular formula C9H6O4, molecular weight 178.14 g/mol, with two adjacent hydroxyl groups at the 6 and 7 positions of the coumarin backbone — the catechol-type arrangement responsible for its primary bioactivities. Typical purity in research/supplemental contexts is ≥98%. Bioactive compound concentration is 100% of the substance by definition as an isolated compound. Preclinical dosing ranges of 100–500 mg/kg (animal studies) provide a reference frame, but no established human dietary intake level exists. Bioavailability data is limited to preclinical models: aesculetin demonstrates moderate oral absorption with first-pass hepatic [metabolism](/ingredients/condition/weight-management); it undergoes glucuronidation and sulfation, producing phase II conjugates that circulate in plasma. Lipophilicity is low (LogP approximately 0.94), limiting passive membrane permeability, though the catechol moiety enhances aqueous solubility (~0.5 mg/mL in water at 25°C). No caloric value is attributable. Co-administration with lipid carriers or piperine may enhance absorption based on structural analogy to related coumarins, but direct bioavailability enhancement data for aesculetin specifically remains limited to in vitro studies.

## Dosage & Preparation

No clinically studied human dosage ranges are available as human trials are absent. Preclinical animal studies used 100-500 mg/kg doses for [hepatoprotect](/ingredients/condition/detox)ion effects. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Safety data for aesculetin in humans is currently unavailable due to the lack of clinical trials. As a coumarin derivative, potential concerns may include hepatotoxicity with prolonged use or high doses, though this has not been specifically documented for aesculetin. Possible interactions with anticoagulant medications should be considered given its coumarin structure. Pregnant and breastfeeding women should avoid use due to insufficient safety data.

## Scientific Research

No human clinical trials, RCTs, or meta-analyses for aesculetin were found in the research dossier. All available evidence comes from preclinical animal models and in vitro studies, with doses of 100-500 mg/kg showing improvements in antioxidant enzyme levels like catalase (CAT) and superoxide dismutase (SOD) in [lipid peroxidation](/ingredients/condition/antioxidant) models.

## Historical & Cultural Context

Aesculetin is a key ingredient in traditional Chinese medicine Qinpi, derived from dried branch bark of Oleaceae plants from regions including Shanxi, Henan, and Shandong. It also appears in various toxic and medicinal plants beyond TCM applications.

## Frequently Asked Questions

### What is the effective dosage of aesculetin for liver protection?

Animal studies suggest hepatoprotective effects at doses of 100-500 mg/kg body weight, showing enhanced catalase and SOD enzyme activity. However, no human equivalent doses have been established through clinical trials.

### Can aesculetin interact with blood thinning medications?

As a coumarin derivative, aesculetin may potentially interact with anticoagulant medications like warfarin, though specific interactions have not been documented. Consultation with healthcare providers is recommended before combining with blood-thinning drugs.

### How does aesculetin compare to other antioxidants?

Aesculetin demonstrates free radical scavenging through hydroxyl group-mediated mechanisms and enhances endogenous antioxidant enzymes like catalase and SOD. Unlike some antioxidants, it shows specific hepatoprotective properties, but human comparative studies are lacking.

### Is aesculetin safe for long-term use?

Long-term safety data for aesculetin is not available from human studies. While animal studies at 100-500 mg/kg showed no acute toxicity, chronic safety and potential hepatotoxicity concerns associated with coumarins require further investigation.

### What natural sources contain aesculetin?

Aesculetin is naturally found in various plants including horse chestnut (Aesculus hippocastanum), chicory, and some citrus fruits. The bioavailability and therapeutic concentrations from natural sources versus isolated compounds may vary significantly.

### What does the current clinical research show about aesculetin's effectiveness in humans?

Most evidence for aesculetin comes from preclinical and animal studies, with limited human clinical trials to date. While animal models demonstrate antioxidant, anti-inflammatory, and hepatoprotective effects, these findings have not been consistently replicated in human populations. More rigorous clinical trials are needed to establish efficacy and optimal dosing in humans before making definitive health claims.

### Is aesculetin safe for pregnant or nursing women?

There is insufficient safety data on aesculetin use during pregnancy and lactation, and it is generally not recommended without medical supervision during these periods. As a coumarin compound, aesculetin carries theoretical anticoagulant properties that may pose risks during pregnancy. Pregnant or nursing women should consult a healthcare provider before using aesculetin supplements.

### What is the difference between aesculetin and aesculin, and which is more effective?

Aesculetin is the aglycone (non-sugar) form of aesculin, a coumarin glucoside found in horse chestnut seeds; aesculetin is the active compound after aesculin is metabolized. While aesculin may be more bioavailable in some formulations due to its glycoside structure, aesculetin is the actual bioactive molecule responsible for antioxidant and anti-inflammatory effects. Direct comparative human efficacy studies between the two forms are lacking.
