Wheatgrass powder is a nutritional supplement that is a concentrated source of vitamins, amino acids, minerals and chlorophyll. Proponents claim that the powder helps to control blood pressure and fight diseases such as cancer and arthritis, but insufficient scientific evidence is available to support these claims.
Sold as a tablet and juice, wheatgrass or Triticum aestivum, is made from the cotyledons of the wheat plan and is gluten-free. Wheatgrass fans say that its high chlorophyll content helps to detoxify the body, strengthen immunity and clean the gastrointestinal tract. Popular among bodybuilders because of its high amino acid content, proponents claim that wheatgrass helps combat obesity and can be used as an antiseptic. Wheatgrass can cause nausea, appetite loss and constipation, and pregnant women should avoid it.
