The latest scientific research has focused on aloe vera gels and creams and has been conducted in dermatology. Further research on the action of Aloe vera gel on gingivitis has not confirmed its effectiveness. In addition, other clinical trials have been carried out in the field of the treatment of diabetes, genital herpes and chronic constipation. Some results indicated that a topical product containing 0.5% Aloe vera extract was much more effective than placebo in helping to treat lesions caused by genital herpes.
