What are the thing to be considered while collecting the medicinal plant.

Before collecting any, determine first how much of the plant and what parts are needed to prevent wastage. Collect only the plant parts you need. For instance, if you need only the leaves, take only the leaves and only the number that you need. Medicinal plants should be conserved to ensure their continuous supply.
