Did you know that lemons can lighten age spots?

Use a small piece of lemon and apply it to the age spot.  Leave it on for about a hour.  You can also soften elbows by cutting a lemon in half, sprinkling baking soda on each half and rubbing the lemon halves on your elbows as if juicing the lemons.  This article lists 22 uses for lemons.

Another citrus benefit is grapefruit seed extract.  I keep a bottle of GSE concentrate around to treat sinus infections and oral thrush.  There are many uses for this versatile product such as: fighting candida, chronic fatigue, colds, fungal infections and in cleaning and laundry applications.
