Primary processing of medicinal plants
Proper drying and storage of medicinal plants for future use are
important since moisture encourages the growth of molds and other
microorganisms, leading to the destruction of the active principles and the
deterioration of the plant drug.
Air-drying and sun-drying are the methods employed in the
absence of temperature-controlled ovens. Properly dried leaves crumble easily.
Small amounts of material may be dried in a large transparent
container in a sunny window, such as an uncapped large jar.
Large amounts may be hung in bundles, baskets, mesh bags,
outdoors or spread on a clean mat in warm, dry place indoors.
Avoid drying on top of concrete pavements or roof-tops; extreme
heat could destroy some of the plant constituents.
Prevent growth of molds and other microorganisms, infestation by
insects and rodents by keeping the dried plant drugs inside air-tight containers
in a cool, dry place away from direct light.
Stored medicinal plants must be labeled inside and outside the
container; include the date of collection in the
