Science
Mechanism of Action
The primary mechanism of action for Fibraurea Recisa Root Extract is attributed to its alkaloid content, such as palmatine and berberine. These compounds are known to reduce inflammation by modulating multiple signaling pathways, exert broad-spectrum bacteriostatic, antiviral, and antifungal effects, and enhance the phagocytic activity of white blood cells. Additionally, the extract contributes to antioxidant defense and may influence keratinocyte processes within hair follicles.

Key findings
- 01 In vitro studies on Fibraurea recisa identified antifungal activity against Candida strains and Cryptococcus neoformans, with effective concentrations ranging from 0.00025% to 0.032%. Berberines demonstrated particular potency.
- 02 Research involving Fibraurea tinctoria (often used interchangeably with F. recisa) demonstrated anti-inflammatory effects, with five identified components inhibiting NO production from macrophages at concentrations between 0.0001% and 0.0004%.
- 03 Antimicrobial activity of Fibraurea tinctoria extracts was observed against Bacillus cereus and Staphylococcus aureus, showing inhibition zones and MIC/MBC values corresponding to concentrations from 0.0025% to 0.01%.
- 04 Antioxidant capabilities of Fibraurea tinctoria extracts were confirmed via the DPPH method, with IC50 values indicating activity at concentrations of 0.00788% (chloroform extract) and 0.00836% (methanol extract).

Dusting Analysis
Effective concentrations for various activities of Fibraurea Recisa Root Extract (or related species) are notably low, typically below 0.032%. Formulations exceeding 0.05% may be utilizing the ingredient primarily for marketing claims rather than enhanced efficacy, particularly if concentrations are significantly above 0.1% without specific justification for such high levels.

Formulation
Stability
The active ingredient Palmatine is readily soluble in hot water, slightly soluble in room temperature water, ethanol, and chloroform, but nearly insoluble in ether. Specific optimal pH ranges for the overall extract's stability are not detailed in current research.
Safety
Safety Profile
Comprehensive safety assessments by regulatory bodies such as CIR or SCCS for cosmetic use of Fibraurea Recisa Root Extract are not available. The FDA status for cosmetic application is also unspecified in current data, suggesting a need for more detailed safety evaluation before widespread use.
