Storage of Medicinal Plants

• Dry extracts are usually very homogenous and should therefore be ground, mixed under conditions, which exclude moisture as much as possible.
• Intermediate and end products must also be stored under dry conditions.
• Packaging the products in suitable moisture tight synthetic foils has proven a good method for this.
• The general requirement of packaging materials are as follows:

a) Economical or low cost

b) Impermeable as glass or metal or with acceptable permeability to moisture, gases, volatile solvents, etc.

c) Non-reactive

d) Easy to manufacture in a wide range of shapes

e) Easy to decorate and or print by a range of processes

f) Able to optimize use of space when stacked or during transportation.
