Chlorophyll is the substance responsible for the green color in plants that accomplishes photosynthesis.
Chlorophyll has been used traditionally to improve bad breath, as well as to reduce the odors of urine, feces, and infected wounds. Chlorophyll has anti-inflammatory, antioxidant, and wound-healing properties.1 2
Historically, chlorophyll was used for gastrointestinal problems, such as constipation, and to stimulate blood cell formation in anemia. Some preliminary evidence suggests that chlorophyll might help detoxify cancer-promoting substances.3 4
Good dietary sources of chlorophyll include dark green leafy vegetables, algae, spirulina, chlorella, wheat grass, and barley grass. Supplements of chlorophyll as powder, capsules, tablets, and drinks are also available.
Chlorophyll has been used in connection with the following conditions (refer to the individual health concern for complete information):

Halitosis (bad breath) |
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary
studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use,
or the herb or supplement has little scientific support and/or minimal health benefit. |

Because chlorophyll is not known to be an essential nutrient, a deficiency does not exist. People who do not eat plenty of green foods lack chlorophyll in their diets.
Optimal levels remain unknown. Chlorophyll in the amount of 100 mg two or three times per day can be used to treat bad breath.
No side effects have been reported with the use of chlorophyll.
At the time of writing, there were no well-known drug interactions with chlorophyll.
