Results of googling....plus my opinion....
�Earth Clinic�..results of a Ukranian Doctor��no scientific trial�all anecdotes.
�Colon Cleansing Zone��Dr. Karash again�all anecdotes and no scientific trials
Wikipedia�same story, no scientific trials.
Scientific evidence,,,2trials only from a study in an Indian Dental school which showed that oil �swishing 2 in the mouth was effective against streptococcus mutans.
Streptococcus mutans is a normal inhabitant of the mouth and it is a contributing factor in tooth decay.
Oil Pulling ("OP") is reported to cure: Mouth & Gum Disease; Stiff Joints; Allergies; Asthma; High Blood Sugar; Constipation; Migraines; Bronchitis; Eczema; Heart, Kidney, Lung Diseases; Leukemia; Arthritis; Meningitis; Insomnia; Menopause (hormonal issues); Cancer; AIDS; Chronic Infections; Varicose Veins; High Blood Pressure; Diabetes; Polio; Cracked Heels
None of the above have been shown to be due to st.mutans except �Mouth and Gum Disease�
Clean your teeth, use a mouth wash, just as effective and less �messy� than �oil pulling�
