What is the best home remedies for yeast?

You need proper medication. Assuming this is about a vaginal yeast infection, you can self treat with one of the many available over-the-counter vaginal creams, inserts, etc. Look for active ingredient ending in "azalea" (miconazole, clotrimazole, etc). All are equally effective; you can choose the least expensive. If that doesn't clear up your symptoms in a few days, get seen professionally.
