Scientists have known the deodorizing properties of chlorophyll for sometime and this is why some products like chewing gum and breath fresheners contain chlorophyll.
Because chlorophyll has the ability to kill odor-producing bacteria, wheatgrass can mask and eliminate the smell of garlic and fights bad breath, body and menstrual odors. Odor-causing bacteria live without air and are destroyed by chlorophyll's oxygen-producing agents.
The cleansing action of fibers in wheatgrass expels retained garbage from the digestive system and promotes regular bowel movement.
For fresher breath, gargle with small amount of wheatgrass juice. You can also brush the back of your tongue with a toothbrush soaked in wheatgrass juice. Wheatgrass should also be taken regularly to prevent displeasing body odors.
