Medicinal plants (PG 101) Level 1 Clinical Pharmacy-PharmD

Advantages of cultivation of medicinal plants:

1. A large number of plants could be concentrated in a small area, therefore

simplifying the plant collection.

2. Control of the purity of the product due to supervised collection.

3. Improvement of the drug by controlling certain factors in cultivation as:

• Treatment of seeds before cultivation to ensure germination, e.g., soaking

hyoscyamus seeds in sulphuric acid fastens germination and their treatment

with colchicine increases the alkaloid content of crop.

• The use of fertilizers or manures, which increase the active constituents

of the plants by providing the essential elements for plants nutrition such as

nitrogen, potassium, and phosphorus.

• Controlling the insects' infestation.

4. Cultivation assures a regular and constant supply and helps to break down

monopolies such as in cases of Cinchona, Cloves and Nutmeg.

5. Cultivation of drugs in proximity to the factory for the manufacture of

galenicals is also a distinct advantage for making fresh green plant.

6. Cultivation helps study of the constituents of plants grown under controlled

conditions.
