        The Longan pericarp  also contain Oligosaccharides  which is polysaccharide sugar form that can increase the number of normal flora such as Bifidobacteria and Lactobacilli in digestive system,

     1.  Reduce pathogen bacteria  :  Bifidobacteria  will  produce antiseptic enzyme to inhibit the growth of Clostridium perfringens, Salmonella spp. and  E. coli in digestive system.

       2.  Improve digestive system   Bifidobacteria  will help increase the colon movement  by adding moisture.

       3.  Reduce blood cholesterol  : By Lactobacillus acidophilus  and inhibit cholesterol absorption through the colon  wall.

       4.  Reduce high blood pressure  :  Study shows that blood pressure is correlate with Bifidobacteria in digestive track.

       5. Increase vitamins  :  Bifidobacteria  can produce vitamin B1, B2, B6, B12, nicotinic acid , folic acid and increase the Calcium absorption in digestive system.  

     6.  Reduce toxic material and enzyme : By reducing pathogen bacteria metabolism, help improving the liver function.
