Abstract
Sixteen traditional medicinal herbs that are used in Indian traditional
medicine and which are commonly available in Tamil Nadu were collected
for the study. Different medicinal parts of the herbs were selected and dried
and grounded under aseptic condition. To determine the in vitro
antimicrobial effect, aqueous and ethanol extracts were prepared and tested
against Staphylococcus aureus, Escherichia coli, Salmonella entitidis and
Clostridium perfringens. Allium sativum bulbs (Garlic) showed
significantly higher zone of inhibition against Staphylococcus aureus,
Escherichia coli and Salmonella entitidis when compared with Syzygium
aromaticum bud (Clove). Other extracts evinced no zone of inhibition. In
the case of Clostridium perfringens, Syzygium aromaticum bud (clove) was
the only herb showed zone of inhibition. Among the ethanol extracts tested
Syzygium aromaticum bud (Clove) showed significantly (p<0.05) higher
zone of inhibition against Staphylococcus aureus, Escherichia coli and
Salmonella entitidis. Murraya koenigii leaves (Curry leaves) was found to
have highest zone of inhibition against Clostridium Perfringens.
