It's benefits are the same as real lemon juice - a source of vitamin C. And can be used to lighten blonde hair (by applying it to the hair, not by drinking it.)
No you cannot. Lemon juice is used to achieve a specific ph in the finished product to avoid spoilage. The lemon juice should be bottled not squeezed fresh as bottled juice has a specific ph level, fresh fruit varies in its ph level by brand and ripeness of lemon.
I did the master cleanse a year ago, so similarly I think it's 2 tablespoons of fresh lemon juice to 8 oz of water. That equals to about half of a lemon.
To make refreshing lemonade using fresh lemon juice, squeeze fresh lemons to extract the juice, then mix the juice with water and sugar to taste. Chill the mixture in the refrigerator before serving over ice.
The apple will be fresh longer. Since the acid in the apple makes the apple turn brown the lemon juice keeps it from doing that.
