You may use your own fresh green tea for a gargle solution. Use a stronger loose leaf like gunpowder or Japanese sencha, and let it cool to a comfortable temperature before gargling.
Or you can use green tea powder from capsules for convenience.
Gargling with green tea extract is as easy as opening a green tea capsule.
Just add a quarter capsule of the powder in one ounce of warm water and gargle.
Once your green tea is in water, it loses effectiveness within a few hours. So always make a fresh batch each time you gargle.
