Pharmacological classification Advantages
 Even if the chemical constituents of crude drugs are unknown, they
can be classified properly on the basics of therapeutic uses.

Pharmacological classification Disadvantages
 Regardless of their morphology, taxonomical status or chemical
nature, drugs are grouped together provided that they exhibit similar
actions/uses. e.g. Senna, Castor oil, Jalap and Colocynth are grouped
together as purgatives because of their common pharmacological
action.
