Objectives: The purpose of the study was to evaluate saliva and tongue coating pH and also to assess the degree of tongue coating in healthy subjects before and after chewing herbal leaves (tulsi, mint, and curry leaf). Materials and Methods: A double-blind, randomized, concurrent, parallel-group study was conducted among 60 volunteer subjects, who were randomly assigned into three groups of 20 each (tulsi, mint, and curry leaf) and were asked to chew five to six fresh leaves of the respective plants twice daily for 7 days. Salivary and tongue coating pH were measured by a digital pH meter and color pH indicators. Data were analyzed statistically using repeated measure analysis of variance and Student's t-test. Results: Mean salivary pH values showed an increase immediately and 30 min after chewing the herbal leaves. A significant difference (P < 0.01) was observed between mint and curry leaf groups immediately after chewing and between tulsi and curry leaf groups (P < 0.05) 30 min after chewing the leaves. Tongue coating pH showed an increase toward alkalinity in all the groups. The assessment of tongue coating showed an increase in scores among tulsi and curry leaf groups, but this difference was not statistically significant. Conclusion: Chewing traditional medicinal plant leaves can be considered as safe, effective, and economical alternate options for maintaining good oral health.
