What this trial studies

This study evaluates the safety and efficacy of super-concentrated, freeze-dried aloe vera capsules for treating interstitial cystitis. Participants will be screened for eligibility and then randomized in a double-blind manner to receive either aloe vera or a placebo. The dosing regimen will increase over the first three months and then decrease in the fourth month, with participants monitored for a total of sixteen weeks. The study aims to determine if aloe vera can effectively alleviate urinary frequency and bladder pain associated with the condition.
