CLASSIFICATION OF NATURAL DRUGS

INTRODUCTION

The crude drugs obtained from different natural sources are used in treatment of wide spectrum of diseases. For their adequate study, it is necessary to arrange them in scientific and systematic manner. Their huge number and varied occurrence make it difficult to put them in a uniform pattern.

For pharmacognostic study, crude drugs can be arranged in one of the following classes.

ALPHABETICAL CLASSIFICATION

Either the Latin names or English names of drugs are considered for this purpose of classification. This classification is adopted by the following books.

1. British Pharmacopoeia (English).
2.British Pharmaceutical Codex (English).
3. United States Pharmacopoeia (English).
4. Pharmacopoeia lnternational (Latin).
5. Indian Pharmacopoeia (English).
6. British Herbal Pharmacopoeia (English).

However, this type of classification does not help in distinguishing the drugs from plants, animals or mineral sources and also does not indicate whether they are organised or unorganised.

CINNAMON AS ANTI MICROBIAL AGENT

Hands are primary mode of transmission of microbes and infections. Through hand hygiene a simple and least expensive means of prevent health care associated infections specially derived from environmental surfaces. The present research was aimed to evaluate the antimicrobial efficacy of Cinnamon oil extract found that it showed better antimicrobial activity. Also the research was carried out to formulate and evaluate the Hand wash gel containing Cinnamon oil.

WONDER DRUG FAKE OR REALITY ?

1938: Di-ethyl stilbestrol (DES) was created. DES was the first synthetic estrogen ever synthesized; it was cheap to produce, more potent than natural estrogen, and could be taken orally. In the rush to make and market DES, Eli Lilly became one ofthe drug's major manufacturers. In America alone there were 267 drug companies that made and distributed DES and other similar synthetic estrogen because it was un-patented and easily produced.No controlled studies were ever conducted by the drug companies to determine the effectiveness or safety of DES for use during pregnancy, even after some scientists started questioning its efficacy in the 19505. As early as 1953, research revealed that DES did not work that DES actually brought about higher rates of premature birth and infant mortality yet DES continued to be prescribed to pregnant women for decades.
