I was just about to ask this - if you had used any other application or herbal medication.
I feel that the possibilities are -
1. Vaginal candidiasis.
2. Local allergic response or inflammation due to the irritant or contact dermatitis due to oil.
3. Bacterial Vaginosis - unlikely as it is only itching and not other symptoms like pain or fever.
I suggest -
1. Tablet Hydroxizine 25mg at 12am/6am/12pm/6pm (Non OTC)
2. Syrup Benadryl (12.5mg/5ml) 10ml at 3am/9am/3pm/9pm (OTC)
3. Topical emollients and lotions will help.
If not settling - you might require - vaginal swab for culture and sensitivity so that we will have a microbiological diagnosis please.
