eben without beeing a Scientologist I can tell you that sweating is a great detox meaure. I used a infrared sauna bought next to nothing in the internet.
But you should be aware of the following:
If you use such a sauna make sure to take about 10 grams of activaed charcoal 2 to 3 hours before your sauna trip. Toxins released by the liver and guts get will be absorbed by the charcoal.
Furthermore form my experience (20 LFs so far)detoxing should be a continuous process. Liver Flushing
alone is not sufficient IMHO. As Andreas stresses modifications in your life style, regular meals, enough water intake, regular bedtimes and the proper organis diet are important things.
I personally use activated charcoal internally on a regular base so interrupt the so called enterohepathic cycle. Thus, toxins excreted by the liver are prevented from being reabsorped in the colon. The results are impressive - at least in me, because I was highly intoxicated.
