One popular yeast infection remedy is an apple cider vinegar bath. Vinegar has many medicinal uses, some more proven by research than others. When you add a half cup of apple cider vinegar to a lukewarm bathtub and soak for 20 minutes, the acidic component of the vinegar is supposed to eliminate any harmful microorganisms.A vinegar bath is not the same as vinegar douching, which aims to flush out all bacteria (good and bad) from your vagina. Doing so leaves you more prone to a recurrence of the yeast infection.source: healthline.com
