Wheatgrass      
All grasses are made up of hard to digest, not very nutritious cellulose and grass juice. Humans cannot digest cellulose and even the animals which are adapted to do so don't find it easy (ever wonder why a cow has 3 stomachs!). The grass juice, on the other hand, contains all the nutrition and is extremely easy to digest.

Said to be almost nutritionally perfect, containing a vast array of vitamins, minerals, and enzymes. It is also one of the richest sources of chlorophyll (around 70%), a wonderful source of instant energy.

It is best taken daily but due to its concentrated nutrient content only a small amount is needed (between 60-90 mls or 4-6 tablespoons daily).
It contains Superoxide dismutase (SOD) an antioxidant enzyme which combats harmful free radicals formed by the action of radiation, pollution and food additives.
The protein digesting enzymes in wheat grass juice can help with allergies as most allergens are undigested proteins.
A substance in the tips of young grass has been shown to have similar effects to root auxins, which are capable of regenerating damaged cells.
The fraction P4DI in wheatgrass juice is capable of regenerating RNA/DNA as well as possessing exceptional anti-inflamatory properties. In tests, it was found to give better results than the steroid cortisone without the side effects.
Wheatgrass juice contains an array of digestive enzymes capable of breaking down toxins and hard to digest substances in food.
It can help stimulate a sluggish liver.
Because it is aerobic and anti-putrefactive, wheatgrass juice can safely help with candida infections.
Wheatgrass juice contains as much carotene (which the body can convert to vitamin A) as carrots.
Gram for gram, wheatgrass has about the same protein content as meat, but unlike meat, it is totally digestible and alkaline forming.
If grown in the right soil, it is capable of of picking up over 90 of the 102 minerals used by the body.
It is a rich source of mucopolysacarides, which are anti-inflammatory and have the ability to strengthen the tissues of the heart and arteries while reducing cholesterol levels.
