Interventional
Description of intervention(s) / exposure
Participants will be directed to take one capsule orally per day in the morning, with food for 24 weeks.
Arm A capsules - contain 700 mg of powdered Eucalypt sap resin
Compliance will be monitored by return capsule count
A subset of women in each group (maximum n=12) will be offered vaginal microbiome testing. This is exploratory testing and will be offered at the researchers discretion.

Summary
Brief summary
The purpose of this study is to assess safety of internal eucalypt sap resin consumption and also to explore if a low dose taken over a period of six months may be able to decrease vulvo-vaginal candidiasis episodes and concurrent gastrointestinal symptoms in women with recurrent vulvo-vaginal candidiasis (RVVC) and gastrointestinal symptoms of microbial imbalance.
With the prevalence of RVVC and lack of safe long-term treatments for managing the symptoms of candida overgrowth (both gastrointestinal and vaginal), we are investigating this ingredient for potential in the management of RVVC alongside long-term safety.
