If a woman’s vulva smells bad and there are no other abnormalities, she can wash it with warm water once a day, wear loose underwear, and do not eat spicy or cold food for a while. If a woman’s vulva has a bad smell and is accompanied by increased leukorrhea and itching, most of the cases are combined with vaginitis. If fungal spores are present, baking soda should be used to cleanse the vulva and vagina and intravaginal pessary should be placed. If there are clue cells or trichomonas growth, you need to wash the vulva and vagina with cleanser and then place metronidazole pessary or tinidazole pessary in the vagina for treatment, which is usually effective in 5-7 days.
