Science
Mechanism of Action
This extract functions by promoting the proliferation of human epithelial cells, including vital skin keratinocytes and fibroblasts, achieved through the enhancement of growth factor receptors and energy production within these cells. Rich in polyphenols, Plantago Ovata Leaf Extract exhibits antimicrobial, antioxidant, and anti-inflammatory activities, supporting overall skin protection and regeneration. It also aids in wound healing processes and acts as an emollient.

Key findings
- 01 In vitro studies demonstrate that a Supercritical Fluid Extraction (SFE) Plantago ovata leaf extract (40 °C) exhibited antimicrobial efficacy against *Bacillus subtilis* and *Candida albicans* within a concentration range of 15.62 µg/mL (Minimum Inhibitory Concentration) to 31.25 µg/mL (Minimum Bactericidal Concentration).
- 02 A topical formulation combining Plantago ovata and vinegar significantly improved rural cutaneous leishmaniasis lesions, showing substantial reduction in lesion area over 8 to 12 weeks, indicating its wound healing potential.

Formulation
Stability
Optimal conditions for mucilage extraction suggest a pH of 7.38. Thermal degradation of phenolic compounds is unlikely to be significant at temperatures up to 80 °C during extraction, though prolonged exposure at elevated temperatures should be monitored to preserve integrity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet reviewed Plantago Ovata Leaf Extract. No specific GHS hazard statements have been identified for the extract itself. However, common allergy symptoms have been reported in workers exposed to inhaled dust from the general Plantago ovata (psyllium) husk, indicating a potential for sensitization from the raw material in powdered form.
