Purified Water

• Bring four cups of water to a rolling boil for 10 minutes, then turn off the burner but do not remove the pan. When it has stopped boiling, add your ingredients.
  
  

Steeping

• To the water add four prepared bags of unflavored green tea in natural casing, then two teaspoons of fine grain table salt (avoid sea salt, as its coarse consistency is not suitable). Stir until the water darkens and allow to rest on the burner for 20 minutes.
  
  

Strain and Cool

• Pour the mixture through a cheesecloth, coffee filter or tea-strainer and allow it to cool to room temperature. Store in a sealed container and refrigerate. Using this mixture will cool and soothe the eyes without the use of chemicals.
  While there is no maximum number of times it can be used, if irritation persists after 24 hours consult an optometrist. Dispose of the mixture after 48 hours.
