Evaluation of drying modelling on common herbs leaves: application to hibiscus rosa-sinensis / Khairunnisa Nabilah Fairul Azahar and Dr Nor Fariza Ismail

Hibiscus rosa-sinensis is well known for its medicinal benefits, particularly the leaves which are abundance in anti-inflammatory, anti-infectious, antifungal, antimicrobial, anti-diarrhoeal, antioxidant, and antipyretic activities. The medicinal plants are high in value and the post-harvest causes...
