There are all sorts of ways to cleanse the body of foreign substances and toxins, but a few of those ways include the old sea-salt flush, coffee detoxification, foot detoxification, as well as other conventional methods, too.
People should also be aware that certain meditation techniques have been known to rid the body of residual toxins. This is because meditation and relaxation can reduce the amount of toxin-producing acid in the body. Balancing your body to it's normal acid/alkaline level enhances the natural ability of the body to heal itself.
For now, we will detail just a few types body detox systems.
In his self confidence course 
(CD #5), Brian Tracy describes the sea salt flush like this:
Disolve 2 level teaspoons of sea salt (not regular salt) in a quart (950 milliliters) of warm water. Drink first thing in the morning on an empty stomach.
This will flush out your entire system in approximately one hour.
I have done the Sea Salt Flush and the taste is really disgusting, however, I always feel better after doing it. I try and do this at least once a year for general health.
However, if one is going to complete a coffee enema then the first thing that is needed is the ingredients. Because typical commercial coffees, such as Folgers and other popular name brands are not produced for total body detox plans, one will need to look to the organic section of the grocery store.
Purchasing organically grown coffee beans (ones that aren't sprayed with pesticides) and boiling it just as you would any other coffee beans is necessary. After you have separated the liquid from the coffee grounds only then should you place it in the enema to get started.
One of the reasons that many people choose body detoxification diets is because they think that it will actually help them and their bodies:
However, many advocates of the detoxification diet claim that our body's immune system will be strengthened even more. If this is so then these individuals should continue to explain how people are just as healthy without the detoxification diet.
On the other hand, one must consider the fact that the body does have a natural detoxification process in order to cleanse the body. Indeed, there are various recipes for detoxification liquids and juices, however, let's examine what the body does first.
In fact, the kidney is so smart that it is able to filter out all of the good blood for the wastes that it intends to excrete when it's time for the body to get rid of them. In the same way, though, the colon is also very instrumental in helping carrying out the same processes throughout the body.
For example, some parts of the detoxification diet include having an individual drink gallons upon gallons of water each day that they are undergoing the diet. This may be very useful for cleansing the inside of the body, but think about the dangers of also consuming too much water in one day.
The kidneys and other organs that are a part of the body's excretion systems are only able to work so hard and if they are overloaded then this certainly is not good for the body.
Having Said All That - There is little advantage to eating all the right foods if you are unrested, stressed, always worried, over worked and sleep depraved. Burning the candle at both ends is a debt which must (and will) be repaid!
All in all, a detoxification process may be just the diet that some people may need to get themselves on the right track toward a healthier lifestyle, but it certainly is not the be-all-end-all in the health and wellness world.
One must also attempt to discover the causes which lead to the undesireable effects in the first place. One of the most simple ways to do this is by having regular quiet-times or meditations in order to bring to the surface what is really bothering us.
The intestinal tract is like a luxury hotel for parasites, bacteria and fungus. It’s warm, it’s moist, and oxygen is limited due to all the waste matter that’s packed in there. The colon – one of the most important organs in the body – is a dumping ground for waste, the place where the body toxins and excess nutrients that could be harmful to the system. It’s also where your body absorbs the nutrients that it needs in order to function and survive – so the health of your colon is mighty important. Parasites in particular can be dangerous to the health of the colon, leeching nutrients from the body and emitting emit harmful toxins that can further weaken the colon’s integrity. This can lead to a number of problems, from the mildly annoying to the deadly, such as:
It’s estimated that over 90 percent of Americans contract a parasite of some kind at some point in their life. They enter our bodies from a variety of sources, including pets, food and unwashed hands. You can pick up parasites from contact with pets and other people, or just by walking barefoot. Children are easily infected by being less aware of hygiene and playing with dirt and other possible contaminated substances. But meat consumption is probably the biggest contributor to parasites flourishing in our bodies.
Eating meat can cause constipation, and constipation creates the perfect environment for parasites to thrive. These unwelcome guests multiply in the haustras, the pouches in the colon where debris is stored. At their least offensive, they cause intestinal gas – but if you experience any of the symptoms above, even something as seemingly minor as chronically itchy skin, you could very well be harboring parasites in your colon.
There are several families of parasites: Roundworms, Tapeworms, Flukes and Single Cell parasites. Each group has its own unique subset of parasites who do different things to your body. Let’s look at some of the more common intestinal parasite and what you can do to avoid them:
Giardia lamblia are protozoan parasites that infect humans via consumption of contaminated food and water. It’s commonly found in untreated water supplies, and is one of the most common causes of diarrhea in travelers, but people sometimes pick them up while swimming in ponds and lakes. Giardia is responsible for the condition known as giardiasis that causes diarrhea, bloating, flatulence, abdominal cramping, weight loss, greasy stools, and dehydration. 
Toxoplasma gondii is another protozoan organism commonly found in the colon. Cats and kittens often carry it, and it can be transmitted to humans who handle of cats – especially their feces. You can also be infected with them by breathing in their eggs. Toxoplasma is responsible for the disease toxoplasmosis, which causes chills, fever, headaches and fatigue. If a pregnant woman contracts toxoplasmosis, it can lead to miscarriage, or birth defects such as blindness and mental retardation. 
Roundworms are are the most common intestinal parasite in the world, affecting over one billion people. They’re also one of the largest parasites, and can grow to up to 30 inches in length. Humans can contract a roundworm infection by eating improperly cooked meat, or by handling dogs or cats infested with roundworms. Symptoms include loss of appetite, allergic reactions, coughing, abdominal pain, edema, sleep disorders, and weight loss. 
Hookworms are able to penetrate the human skin, and often enter the body through the feet when people walk barefoot through contaminated areas. They can be all over the world, in warm, moist tropical areas, and can live in the intestines for up to fifteen years. A hookworm infection may cause symptoms such as itchy skin, blisters, nausea, dizziness, anorexia, and weight loss.
