Application

  • Salinity stress management in agriculture: A study demonstrated the application of salicylic acid in ameliorating salinity stress in barley, revealing its potential to enhance crop resilience to saline environments, thereby contributing to sustainable agricultural practices (Hanif et al., 2024).
  • Enhanced pharmaceutical gel performance: Research on nitrocellulose for prolonged permeation of Levofloxacin HCl-Salicylic Acid In Situ gel emphasized its utility in enhancing drug delivery systems, particularly in treating bacterial infections with improved efficacy (Khaing et al., 2024).
  • Biotechnological production of withanolides: Salicylic acid was applied as an elicitor in the hairy root culture of Withania somnifera, significantly boosting the production of withanolides and phenolic acids, vital for pharmaceutical applications due to their therapeutic properties (Halder and Ghosh, 2024).
