In vitro study on the anti-microbial efficacy of Aloe vera against Candida albicans

October 2018

Oral Candida infections are common among the people who are immunocompromised, with poor oral hygiene, diabetics and advanced age. Even though several effective antifungal agents are available for treating oral Candida infections, on prolonged and frequent treatment with these drugs, they may result in development of drug resistant organisms. This leads to looking for an effective, inexpensive and simple alternative....
