The skin is the largest of the elimination channels. Through the skin toxins are eliminated which are brought to the skin surface from the blood. When the regular elimination channels are sluggish or partial plugged up such as your colon being constipated, not all toxins move out through your feces.
Toxins that accumulate in the colon tend to move into the blood, when colon walls have been weaken through constant constipation or abused through eating excessive junk food. Once in the blood they move into the liver for detoxification.
If you are frequently constipated, than your liver will be overworked and unable to detoxify all of the colon toxins. The liver will store a lot of these toxins in its own tissue and else where in your body's tissues, joints, organs, cells and skin. When your pores are not working properly, excessive toxins in the pores can lead to acne.
When you have excessive toxins and your immune system is not able to detoxify them, these toxins will moved to the skin surface through the blood where they are enter the hair pores - follicles - and try to move to the skin surface. When your pores are not working properly, excessive toxins in the pores can lead to acne.
Body odor is also a result of toxins coming out through the skin that should be moving out through the other elimination channels.
If your body skin is clean and its pores are open and unclogged, toxins will move out through the pores without creating acne, pimples or eruptions. The skin normally moves 1-2 pounds of toxins out of your skin daily.
You can tell when your pores are open. You sweat freely during exercise. If you do not sweat much during hot weather or during exercise, then your skin pores are probably plugged.
To keep your skin active and serving as a good channel of elimination you need to brush your skin daily before you shower or during your shower. When you brush your skin, brush in one direction, starting from your feet towards your heart.
In her book, Detox For Life, 2002, Loree Taylor Jordan, C.C.H., I.D. says,
"One of greatest gifts of health that you can give yourself is the gift of skin brushing. Dry skin brushing in one of the finest of all baths. No soap can wash the skin as clean as the new skin you have under the old. You make new skin on the body every 24 hours. The skin will only be as clean as the bloodstream. Dry skin brushing removes the top layer. This helps to eliminate uric acid crystals catarrh, and various other acids in the body. The skin should eliminate 2 pounds of waste acids daily."
Understanding how your skin lives will help you keep it clean. Brush your skin daily and bring toxins to the skin surface where you can get rid of them during your shower.
