I'm now getting an understand of CS, but still have some questions that I hope 
somone can answer.

1.  My friend is taking and her family are taking  CS  400 PPM ( on the bottle 
)  Accoring to the directions she cuts the dose down to 1/4 tsp instead of 1 
tsp.
2.  I see CS in Health Stores, 10, 20, 400, PPM. I'm still trying to comprend 
the differenct of the sizes of 10,20, 400 PPM.s

Thank you for your help, this list has helped me alot.  Kathy
