A polyherbal mouthwash containing hydroalcoholic extracts of Zingiber officinale, Rosmarinus officinalis and Calendula officinalis (5% v/w) was compared with chlorhexidine and placebo mouthwashes in subjects with gingivitis. Participants were instructed to use the mouthwash twice a day (after breakfast and dinner) for 30 seconds for a period of two weeks. The herbal mouthwash was shown to be effective in the treatment of gingivitis and its efficacy was comparable to that of chlorhexidine mouthwash.
