Methodology table which clearly present the procedures of various stages.

Step	Procedure
1. Henna preparation	Clean, grind, and sieve Henna leaves into a fine powder (250 µm). Dry the powder at 60 °C for 24 h
2. Mixing	Weigh and mix PLA pellets and the dried henna powder in a ratio of 98% PLA to 2% henna
3. Dissolving	Add the PLA/Henna mixture to chloroform. Stir at 1000 rpm and 60 °C for 1 h until a homogeneous solution is formed
4. Film casting	Pour the homogeneous mixture into a glass petri dish to create a thin film
5. Drying	Allow the film to dry at room temperature for 48 h to evaporate all the chloroform
6. Final preparation	Grind the dried film into a fine powder for use in subsequent experiments
