If your friend has the energy to devote to detoxing and is not taking medications which would be affected by fasting, I would imagine a short cleanse could be a good place to start.
If your friend is taking medication, fasting should be supervised, or avoided. If your friend needs to colon cleanse, I could recommend looking at Oxypowder
. It seems to be one of the more popular colon cleansers. I have used it. It takes only 7 days too. Oxypowder
There are other options too and you can check out the Curezone Bowel Cleanse
page for more info.
be happy, be well,
