A fabulously healthy juice drink from Australian chef flip shelton's 'green: modern vegetarian recipes'. Commenting on aloe vera, she says that it "has been described as a natural healer because it contains many essential amino acids, vitamins, minerals, proteins and enzymes" and she suggests giving youself "a dose whenever you feel low". From the instructions, this is clearly intended to be made using a juicer, but you could use a blender. You would then get the whole of the cucumber and apple, not just the juice. If doing this, obviously remove the apple core!
