Home Remedy for a Yeast Infection on the Tongue

By Darla Ferrara

A yeast fungus, Candida albicans, can cause an infection on your tongue called thrush. Symptoms of oral thrush include white lesions or sores that might bleed, and can spread to other areas of your mouth, such as the roof. For people with comprised immune systems, like HIV patients or the elderly, thrush is a common problem. If you're healthy and think you might have thrush, there are some home remedies that might work to relieve it.

Acidophilus is a name for a group of friendly bacteria called probiotics. When purchased in capsule form, it can be crushed and applied to the tongue as a paste until it dissolves. It's not a good idea to do this more than once a day. Exposure to probiotics can sometimes cause adverse affects on your digestive tract, such as diarrhea. Some people, however, take some form of probiotics every day as a dietary supplement.
