Beware of the abuse of 'natural' as having any real meaning.  Folks used to chew willow bark for fever & pain.  It works because it has ASA in it.  It's the same ASA that you'll find in Aspirin.  Your body doesn't know the difference, fewer splinters in your teeth.

Do you take vitamin pills?  They're not 'natural'.  They have been manufactured for a century.  There's no difference between the vitamin you get from a carrot and what you get from Flintsone's Chewables or Centrum.

Natural is often the worst way to treat the problem.  Uncontrolled dosage being the major issue.

That being said, eat fruit!  Eat lots of fruit.  It's good for you.  Chock full of good sugars and water and vitamins and fibre.
