I recently got some vaginal odor. I greatly reduced it by mixing ACV + Water ( 50:50) I also added couple of spoonfuls of borax to it. Wash your vagina 2-3 times with this soultion.
Would be like 2 cups water + 2 cups ACV + 3-4 tbsp of BORAX. SHAKE well in a bottle. Use this solution to thouroughly wash the vagina.
IN my case the smell has greatly reduced. Although I have done it only once a day for the past 3 -4 days.
