Antimicrobial activity of the crude extracts of Houttuynia cordata and Centella asiatica on some human gut microflora

Abstract

C. asiatica and H. cordata plants are used as vegetable since time immemorable by the people of Assam. These are also consumed for their medicinal values. Plenty of information on the action of the plants extract on the pathogens are available, but could not retrieve any information on the non-pathogens of human guts. Therefore, an attempt has been made to find action of the extracts on  few of the non-pathogens of human guts. The study shows that none of the plant extracts inhibit Bacillus coagulans, Bacillus mesentricus, and Lactobacillus sp, whereas a minimum inhibition were recorded in case of pathogens Escherchia coli, Staphylococcus aureus, Klebsiella pneumoniae and Shigella dysenteriae.
