Chlorophyll

Chlorophyll is the green pigment in plants that occurs chiefly in the chloroplasts (specialized cytoplasmic bodies). It is involved in photosynthesis (the manufacture of carbohydrate from carbon dioxide and water, utilizing light energy and releasing oxygen). Because life could not continue without chlorophyll, its importance cannot be minimized. However, the value of chlorophyll in human health and disease is exaggerated by promoters of wheat grass, barley green, blue-green algae, chlorella, cereal grass, and other products. The fact that grass-eating animals are not spared from infectious or degenerative diseases despite their large intake of fresh chlorophyll attests to its limitations. Furthermore:

  • Chlorophyll is not a catalyst.
  • Chlorophyll has no deodorant action.
  • It is not identical to blood in structure or parallel function in plants
  • Chlorophyll cannot affect the human body internally because it is not absorbed.
  • There is no reason why products containing chlorophyll should be considered “natural.” Chlorophyl is extracted by exposing plant materials to chemicals such as acetone, hexane gas and copper. Thus there is no reason why chlorophyll products should be considered “natural.”
  • Chlorophyll’ antibacterial activity is vastly inferior to inferior to that antibiotics.
