Content text 2. CLASSIFICATION OF CRUDE DRUGS.pdf
PHARMD GURU Page 4 GUM AND MUCILAGE: Gums containing crude drugs are amorphous substances, pathological products produced by the plants under injured or unfavourable conditions. Mucilages are thick, gluey substances produced from plants and some microorganisms. The differences between gums and mucilages are given in table 1.7. ADVANTAGES: Easy method to study of plant drugs. Even if the chemical content or action of drug is not known the drug can be studied properly. It gives idea about the source of drugs. It gives idea whether it is organized or unorganized. Easy to identify and detect the adulteration. DISADVANTAGES: During collection, drying and packing, morphology of drug changes; they are difficult to study. No correlation between chemical constituents with therapeutic actions. Repetition of drugs or plants occurs. 3) TAXONOMICAL CLASSIFICATION: This is the systematic naming of organisms into similar groups. Plant taxonomy uses the gross morphology like flower form, leaf shape, fruit form, etc. of plants to separate them into similar groups. Quite often the characteristics that distinguish the plants become a part of their name.
