Have you considered the Master Cleanse salt water flush? Actually, it’s part of a detox program which is known as the Master Cleanse or the Lemonade Diet.
  This program detoxifies your body.
This special lemonade is made from fresh lemon juice (obviously) as well as maple syrup, cayenne pepper and water and you drink this for up to ten days. That’s it. You can also drink water and herbal tea.  By doing this you will clean your body from the inside out and remove excessexcessexcess toxins from your body.
The recipe for one glass of lemonade is as follows:
2 tablespoons of fresh organic lemon juice
2 tablespoons of organic maple syrup
1/10 teaspoon of ground cayenne pepper
10 oz good quality water
You should drink between six and twelve glasses of this lemonade each day.
The salt water flush will assist you with elimination. This is the recipe:
1 1/2 to 2 teaspoons of organic uniodized sea salt

1 quart of water
1 teaspoon of fresh lime or lemon juice if required

You should drink this on an empty stomach as soon as you get up. To be honest, this doesn’t taste good and can be hard to drink it all.  Just try sipping it until it’s gone. Or you can drink say a quarter at one gto and then drink the remainder gradually. If you feel nauseous drinking it, just slow down and sip. If you can’t drink all of it, then drink as much as possible.
Don’t stray too far away from the bathroom as you’ll absolutely need it. Most people who have done this have had a bowel movement within an hour of drinking the salt water flush. In fact you could even have quite a few bowel movements. Should this not be the case, then next time add some more salt.
This is great to help get rid of excess toxins and waste material from your colon. Your blood has almost the same gravity as salt water, which means that your kidneys and your blood will not absorb the salt water
and it will just clean out your digestive system.

Should you have any problems with this, please consult your physician for his advice.
The salt water flush in combination with the Master Cleanse will give your digestive system a much needed cleanse. The flush is a natural enema, it’s cheap and effective.
