For more information on drying medicinal plants:
Medicinal plants drying is a common stabilization technique that preserves essential oil yields and important qualities of bioactive compounds. However, systems and appropriate drying methods remain understudied. This review focuses on drying medicinal plants and how drying affects essential oil yield, antioxidant content, antimicrobial activity, health benefits, color, and aroma of dried goods. Various drying methods are summarized. The preferred drying method for most herbs is oven and freeze drying, but this depends on the type of heat transfer to the surface of the herb and the type of component volatility. However, medicinal plants color retention requires faster drying times. Furthermore, antibacterial and pharmaceutical compounds require intensive research due to their unique properties, which cannot be determined by general drying methods. Since there is no universal drying method, these findings underscore the importance of comprehensive medicinal plants research. However, specific drying patterns can be observed, inspiring future research and drying innovations.
Why Dried medicinal plants?
Medicinal plants are "any plant with leaves, seeds or flowers used for flavoring, food, medicine or perfume". medicinal plants are considered highly perishable foods due to their high moisture content, and most medicinal plants are sensitive to cold. Therefore, they are processed by drying to make shelf-stable products. Drying preserves the quality of medicinal plants by reducing moisture content, thereby inhibiting microbial growth and chemical changes during dry storage
