New natural gel for bacterial vaginosis passes first safety check

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Females aged 18 to 40 years (inclusive) who are pre-menopausal at the time of providing informed consent * You should be generally healthy, with no major past illnesses, and your doctor should not see anything concerning during your check-up before starting the study. * Your BMI (a measure of weight and height) must be between 18.0 and 34.9. * You must be a non-smoker or only an occasional smoker.

Exclusion Criteria: * Women who currently have moderate or severe vaginal symptoms (such as pain, itching, burning, or unusual discharge) at the Screening visit cannot join the study. * Women with physical or mental health conditions that, in the opinion of the study doctor, would make it difficult for them to follow the study rules or finish the study will not be able to participate. * Women who have had certain surgeries, such as: * removal of the uterus (full or partial hysterectomy) major surgeries on the cervix, vagina, or uterus (for example: cervical cone biopsy,removal of the cervix, or major uterine surgery) * cannot participate because these procedures may change the vaginal or reproductive anatomy, which could affect study results. * Women with certain medical conditions, including: a.
