What is a home treatment for a white watery substance that comes out of the vagina?

Unclear problem?: It's normal to have discharge every day from the vagina. Are you concerned because there's more discharge than normal? White and watery is normal. If concerned that too much discharge, or if there's smell, you can increase consumption of 'good' bacteria, lactobacilli. Consider vaginal probiotic as well that can help to restore predominance of lactobacilli. Also look for what may cause irritation.
