Skin & Guts,

We really only have one skin, or one gut. They are the same. Of course, the cells change as the skin changes at the lips, rectum, nostrils, eyes, ears, penis, vagina and goes inside the body from outside of the body. It is all one organ, the largest organ in the body.
Why do we care? Everything that touches the skin is absorbed into the body. More will be absorbed from an oily liquid than from a vinyl sofa, but at least a few molecules of anything we touch will get into our bloodstream. I even read a theory about prostate Cancer caused by sitting for many years on a plastic chair.
Read the labels on suntan lotion, make-up, deodorant, everything that will go on or in the body and they undoubtedly contain harmful chemicals and preservatives. Of course, the body can detoxify small amounts of toxins, but what if all your clothing is plastic, all your plates and napkins are plastic, all your furniture is plastic, everything you use or touch is plastic??? And it is proven that some plasticizers are carcinogens.
I prefer to make my own lotions, shampoos, toothpowder and the like. See Dr. Hulda Clark's book "The Cure for All Diseases" for some recipes. It is sold at www.newcenturypress.com/. I like her recipes because they are passed down for generations and use safe ingredients. See Dr. Mercola's site at www.mercola.com. One of his articles today discusses dandruff and shampoos and he cautions about shampoo chemicals absorbed into the scalp.
One of the most common problems are the types of toxic alcohols used in creams and lotions. I prefer to use triple-distilled vodka to make underarm deodorant and other grooming items. Vodka is ethyl alcohol (ethanol) and one probably cannot use enough as a cream, lotion, or deodorant to get drunk.
There are special large cells called "apocrine" glands under the arms and in the groin area. These soak up efficiently whatever cream, cologne or deodorant that is put there, so it is important to use pure products there, or better, make your own.
The transitional mucuous membranes (mouth, rectum, eyes, penis, vagina, nostrils) are especially absorptive and anything put there goes into the blood stream. Something put into the rectum is absorbed directly into the bloodstream and avoids the saliva enzymes, the stomach acids, the duodenal pancreatic enzymes, the liver. So if you put drugs or drinks or suppositories into your rectum, they will bypass normal digestion and go directly into the bloodstream. This is dangerous, and I read of some college men dying because they put too many martinis into the colon trying for a fast and cheap high.
