In a document of WHO on http://whqlibdoc.who.int/publications/2003/9241546271.pdf , they recommand to wash medicinal plants before air drying them. But most of the research articles that I find out don't take it into account.
I don`t know what u mean, but if u want to examine the antibacterial effect of your plant on a microorganism so u have to first wash your plant, grind it and put it in ethanol for about 2 days, lypholize it (i mean get it as a powder) and then make a solution of it with a definite concentration and finally use it in your experiment
Thx u Sherif. thus, the next step after harvesting the plant materials is to wash them, then air dry, and prepare the plant extract with ethanol.
The plant material generally will have moths lichens, soil and dirt etc., depending on the part of the plant and source. For any kind of biological activity the material is ussually extracted or prepared juice. What ever may be the process, the plant material needs to be cleaned before you process it further.
thx Salleemulla for your contribution.
Is it possible to Have articles talking about process required for using plant material?
Yes,The plant material should be washed with running water and then dry in shade and powdered in a mechanical grinder. Ethanol extract of the plant should examine using a standard antimicrobial disk diffusion method
Well! yess there are a few. There many books which suggests the process required prior to the ussage. Best is WHO guidelines preparation of traditional medicine and standardization.
