level questions: Classification of crude drugs

QuestionAnswer
Classification of crude drugs1 Alphabetical 2 Taxonomy 3 Morphology 4 Pharmacological or therapeutic applications 5 Chemical classification 6 Chemotaxonomical
easy to use with no repetition of entries and is devoid of confusion, but There is no relationship between previous and successive drug entries.Alphabetical
classified according to kingdom, subkingdom, division, class, order, family, genus and species.Taxonomy
based on characters of the plant parts or animal parts, i.e. which part of the plant is used as a drug, e.g. leaves, roots, stem, etcMorphology
based on most important constituent or their therapeutic usePharmacological or therapeutic applications
according to its active constituents eg.alkaloids, glycosides,tannins,etcChemical classification
relies on the chemical similarity of a taxon, i.e. it is based on the existence of relationship between constituents in various plant.Chemotaxonomical
The simplest way In their Latin and English names(common names) Local language names(vernacular names)Alphabetical
Advantage and Disadvantage of Alphabetical classificationAdvantages: 1 Easy and quick to use 2 No repetition of entries 3 Easy tracing and addition of drugs Disadvantages: 1 No relationship between previous and successive drug entries
Advantage and Disadvantage of Taxonomical ClassificationAdvantages: 1 Helpful for studying evolutionary developments Disadvantages: 1 Does not correlate in between the chemical constituents and biological activity of the drugs
Advantage and Disadvantage of Morphological classificationAdvantages: 1 More helpful to identify and detect adulteration More convenient for practical study especially when the chemical nature of the drug is not clearly understood 2 There is no correlation of chemical constituents with the therapeutic actions Disadvantages: 1 Repetition of drugs or plant occurs
More relevant and mostly followed methodPharmacological/therapeutic classification
Advantage and Disadvantage of Pharmacological/therapeutic classificationAdvantages: 1 used for suggesting substitutes of drugs, if they are not available at a particular place or point of time Disadvantages: 1 Drugs having different action on the body get classified separately in more than one group that causes ambiguity and confusion
Advantage and Disadvantage of Chemical classificationAdvantages: 1 it is a popular approach for phytochemical studies Disadvantages: 1 ambiguities arise when particular drugs possess a number of compounds belonging to different groups of compounds.
