(2021) Antibacterial Effects of Aqueous Extracts of Herbal Sticks on Oral Isolates. Algerian Journal of Natural Products 9(1): 820-829.2353-0391https://uilspace.unilorin.edu.ng/handle/123456789/13567This study compared the antibacterial effects of some herbal sticks commonly used for oral hygiene in Ilorin, Nigeria, on oral isolates. Aqueous extracts of the sticks were used to challenge bacteria isolated from various parts of the oral cavity. Stem extract of Distemonanthus benthamianus (Baill) was effective against all the isolates except Pseudomonas aeruginosa, with activity indices ranging from 0.59 to 1.35 compared to streptomycin. Micrococcus species was inhibited by all the extracts while the other isolates including Streptococcus pyogenes, Staphylococcus aureus, Bacillus subtillis, Staphylococcus epidermidis, Streptococcus mutans, Micrococcus luteus, Lactobacillus bulgaricus and Staphylococcus saprophyticus showed various patterns of susceptibility. Inhibition zone ranged from 10.0 mm for extract of Spilanthes calva (DC) to 33.0 mm for that of D. benthamianus. This study showed that herbal sticks have antibacterial effects on oral organisms and their extracts are recommended as components of products used in maintaining oral hygiene.enantibacterialherbal sticksoral hygieneArticle
