Cultivation of medicinal plants

❑ Medicinal plants are either grown wildly or cultivated. Plants growing in their

native land are said to be indigenous to this land. When plants grow in a foreign

land or in a locality other than their nature home, they are said to be naturalized,

introduced, and cultivated.

✓ Collection of wild plants for medicinal use is frequently accompanied by

several disadvantages as follows:

1. Wild plants are found in sparse distributions over unlimited areas so hardly

to collect the target plant without time waste.

2. Difficulty in collection and transport because they are mostly growing in

deserts or forests far from any means of transport.

3. Continuous extensive collection may lead to extinction or a serious

deficiency of the plant.

4. Collection of crude drugs from wild sources may lead to adulteration due to

ignorance of collectors.

5. The collected number of wild plants may be insufficient for the market needs

and may lead to monopoly.
