Problems with Herbal Drugs Preparations(2):-

In the following paragraphs technical aspects of medicinal plant production will be discussed. According to the World health Organization  the botanical identity, scientific name of each medicinal plant under cultivation should be verified and recorded. If available, the local and English common names should also be recorded. Other relevant information, such as the cultivar name, ecotype, chemotype, or phenotype, may also be provided, as appropriate.

For commercially available cultivars, the name of the cultivar and of the supplier should be provided. It’s essential that a voucher botanical specimen used in the experiments be placed in a regional or national herbarium for identification and further consultation by other researchers; it is almost impossible and not advised to publish without the registration numbers. Cultivation of medicinal plants requires intensive care and management. The conditions and duration of cultivation required vary depending on the quality of the medicinal plant materials required. If no scientific published or documented cultivation data are available, traditional methods of cultivation should be followed, where feasible.

Otherwise a method should be developed through research. The principles of good plant husbandry, including appropriate rotation of plants selected according to environmental suitability, should be followed, and tillage should be adapted to plant growth and other requirements. Risks of contamination as a result of pollution of the soil, air, or water by hazardous chemicals should be avoided. The impact of past land uses on the cultivation site, including the planting of previous crops and any applications of plant protection products should be evaluated.

The quality and growth of medicinal plants can also be affected by other plants, other living organisms, and by human activities. The introduction of nonindigenous medicinal plant species into cultivation may have a detrimental impact on the biological and ecological balance of the region. The ecological impact of cultivation activities should be monitored over time, where practical. The social impact of cultivation on local communities should also be examined to ensure that negative impacts on local livelihood are avoided. In terms of local income-earning opportunities, small-scale cultivation is often preferable to largescale production, especially if small-scale farmers are organized to market their products jointly. If large-scale medicinal plant cultivation is or has been established, care should be taken that local communities benefit directly from, for example, fair wages, equal employment opportunities, and capital reinvestment.
