Scavenging free radicals and antioxidant
Grapefruit Extract (GSE) has very high amounts of disease-fighting, free-radical eliminating antioxidants and phytonutrients called bioflavonoids. One of these powerful bioflavanoids (plant antioxidants) include the chemical component hesperidin, a well-known natural immune-system stimulator and booster.

Inhibit the occurrence of colon cancer
Chemical analysis of grapefruit seed extract shows additional antioxidant constituents including Vitamin C, sterols, tocopherols, citric acid, liminoids, and other trace minerals. Studies done on the compounds in GSE's seed and pulp have found that these bioactive agents may be able to inhibit the occurrence of colon cancer.

The commonly-used disinfectant have high levels of toxicity and are harmful to humans, animals and the environment. A recent study done by Microbiologists from the University of Georgia found that GSE was a very effective non-toxic disinfectant. The same study found that GSE demonstrates a "wide spectrum of activity, " including antiviral, antimycotic, and antiprotozoan capacities against many bacteria and viruses, including E. Coli. It was also found to be an effective cleanser as a a pre-surgical soap. Another recent study from The Journal of Alternative and Complementary Medicine found that grapefruit-seed extract was effective in killing over "800 bacterial and viral strains, 100 strains of fungus, and a large number of single and multi-celled parasites. "² No other naturally-occuring anti-microbial can come close to these results.

Treatment of thrush
Thrush is a fungal infection, commonly affecting newborns and persons with immuno-compromised systems. Grapefruit seed extract, apart from possessing immune system bolstering vitamin c, is a proven anti-fungal as well. As thrush is considered an infection localized mainly to the mouth, a good GSE mouth rinse should do the trick in rectifying symptoms. Within four days symptoms should be resolved completely.

Treats gingivitis or bleeding gums
The logic behind this one is simple, gingivitis is a diseased state of the gum line resulting in inflammation and soreness. Now, the cause of this is bacterial in origin, so grapefruit seed extract's anti-microbial effect is a viable option to combat this problem. Bleeding gums commonly result from a deficiency of vitamin c, so in addition to preventing the foul odour that bleeding gums exude, it is loaded with the vitamin to help improve this condition.

Sinus infections
Can help to relieve sinusitis as a result of bacterial infection and inflammation. Becomes even more effective if placed into a nebulizer and inhaled.

Treatment for stretch marks
Even though grapefruit seed extract by itself is not effective in treating stretch marks, when combined with other ingredients such as vitamin e, vitamin a and squalene oil, it has been demonstrated to significantly diminish the appearance of stretch marks.
