Science
Mechanism of Action
This extract exerts its benefits through a diverse phytochemical profile, notably comprising saponins, flavonoids, and phytosterols. These components collectively confer robust antioxidant properties, actively mitigating oxidative stress which is a primary contributor to cellular aging. Furthermore, the extract demonstrates anti-inflammatory actions, which can aid in soothing irritated skin and supporting recovery from various dermal conditions. Traditional uses often link its benefits to 'blood purification,' historically associated with enhanced skin clarity and health. In vitro investigations also highlight its capacity to inhibit α-amylase and α-glucosidase enzyme activities, suggesting a broader biochemical influence.

Key findings
- 01 In vitro studies show a hydroethanolic extract of Smilax aristolochiifolia root significantly inhibits α-amylase activity, achieving an IC50 of 90.01 μg/mL. At concentrations of 50 μg/mL, 100 μg/mL, and 200 μg/mL, it inhibited α-amylase by 22%, 56%, and 82% respectively. A chlorogenic acid-rich fraction (CAF) from the extract also demonstrated α-amylase inhibition with an IC50 of 59.28 μg/mL.
- 02 The same hydroethanolic extract exhibited potent inhibition of α-glucosidase activity in vitro, with an IC50 of 12.39 μg/mL. This inhibition reached 34% at 10 μg/mL, 81% at 20 μg/mL, and 98% at 50 μg/mL. Furthermore, both a chlorogenic acid-rich fraction (CAF) and an astilbin-rich fraction (ABF) derived from the extract effectively inhibited α-glucosidase, with IC50 values of 9.27 μg/mL and 12.30 μg/mL, respectively.

Specific effective concentrations for direct topical skin benefits have not been established through comprehensive clinical trials in the provided research, precluding the determination of dusting thresholds.
The Formula
Formulation
Stability
A hydroethanolic extract indicates solubility in both water and ethanol. Optimal long-term stability for the dry raw material (SAR) is achieved when stored at -80°C, suggesting temperature sensitivity. Solutions utilized in in vitro assays were prepared in a 20 mM phosphate buffer at pH 6.9, implying suitability within this pH range for application.
Safety
Safety Profile
This ingredient is recognized by the FDA Substance Registration System (SRS). SkinSAFE assessment highlights a favorable topical safety profile, designating it 'Teen SAFE' and free from common irritants such as parabens, gluten, nickel, and dyes. The Good Scents Company reports no GHS classification or hazard statements. While generally well-tolerated, rare instances of mild gastrointestinal upset (nausea, diarrhea) or allergic reactions (rash, itching) have been reported, primarily associated with high oral doses (>1,000 mg) taken on an empty stomach.
