Transdermal (through the skin) magnesium chloride is the best detoxification agent known, plus it's cheap and easy to buy. It also helps with diabetes, arthritis, blood pressure, heart disease, heart attack and strokes (both prevention and recovery). It's good for tremors and muscle cramps; acne, warts and itching skin; cerebral and circulatory problems; asthma and hay fever. It also treats viral illnesses like colds/flu/bronchitis/measles/mumps/boils; and it is also good for enzyme processes, muscle pain, insomnia, headaches/migraines, bones/teeth and gums.
The main point of the book is that we are all short of magnesium, which is as important to us as air and water but ignored by the medical system that has lost contact with reality. Sircus calls magnesium a medical miracle, one that should be a priority since we can safely assume we need magnesium if we have any kind of health problem.
Magnesium chloride lotion/oil/bath salts that can be safely applied directly to the skin (transdermally) enable high dosage so magnesium can be brought up to high levels quickly and without diarrhea and problems with absorption. More than that, it turns out that only magnesium chloride (of all the different types of magnesium) is able to protect the cells of our bodies; probably it's a molecular, and not merely ionic, matter.
Transdermal magnesium chloride is the best way (equal to intravenous) as it's very difficult to bring up magnesium levels in the body, long term, in any other way. Any magnesium tablets, capsules or powder are only absorbed at about 40%. It can take up to a year to raise magnesium levels to an adequate level but doesn't always work. (I myself took 1,000mg magnesium citrate for several years without noticeable improvements). It only takes a couple of months using magnesium oil on the skin. There is no other method for successfully increasing levels of DHEA (an anti-aging hormone). Most of us also don't know that calcium supplements will kill you if you don't also take extra magnesium (1:1, not the 2:1 calcium to magnesium advice we've had so far because it's more difficult for the body to absorb magnesium than calcium).
Transdermal magnesium chloride delivers high levels of magnesium right through the skin into the bloodstream and from there directly to where it is most needed, bypassing the common digestive and kidney symptoms associated with high levels of oral (through the mouth) magnesium. There is no overdosing because the skin only takes in what is needed.
Also, magnesium chloride baths help with skin diseases like psoriasis/eczema as well as calming restless/violent tendencies and lifting depression and anxiety. Diluted magnesium oil beautifully cleans and heals wounds without harming the skin. You need more magnesium under stress, whether caused by physical or psychological disease/injury, emotional upheaval or athletic exertion. Stress causes loss of magnesium, and inadequate magnesium levels in the body creates decreased tolerance of stress: a vicious circle.
This edition appears to have been re-written, as it is much more logically put together and arranged than the first edition, it's a pleasure to read. However, in his first edition, but not this one, the author explained that, while there are six tests for magnesium levels in the body, the standard test is the only unreliable one, almost guaranteed to give an inaccurate result. (Curiously, I found this to be the case for EVERY SINGLE supplement I have researched, including thyroid, adrenals and vitamins D, B12 and K2. Could this be evidence of a conspiracy to keep us sick? But of course not.... it's all just coincidence.)
We live in a medical world that ignores the evidence that magnesium is crucial for every single function in our own bodies. From the moment we are conceived to the moment we die, magnesium is at the heart of life, as is air and water. It is that basic and that important. Today, no amount of fruits and vegetables can ensure adequate intake of magnesium because it has not been replaced in our soils for decades.
BTW, in his book on "Sodium Bicarbonate", Sircus repeatedly states that the triumvirate of health recovery involves sodium bicarbonate (the humble baking soda), magnesium chloride and iodine. He has a whole chapter on the usefulness of almost always using sodium bicarbonate with magnesium chloride for greatest effect, with no side effects when used with prudence. Add iodine and "one has the formula for infectious disease control in the 21st century, the age of toxicity and antibiotic-resistant infections."
P.S. While the natural product from sea water (especially the Zechstein bed stuff) is preferable, if you can only get the stuff created industrially from hydrochloric acid or pharmaceutical stuff, which often contains 25 times the heavy metal pollution than natural seawater evaporation solutions, it's still a thousand times better than nothing. In some countries it is the only magnesium chloride product available. They have high levels of lead, and other undesirable elements, and don't feel the same on the skin as natural solutions but to do without, when in need of magnesium supplementation, is like not breathing air when living on earth because of the pollution.
P.P.S. Shamefully, in this revised edition Sircus again virtually ignores side effects. Since when I first tried this I suffered both dizziness and more palpitations than usual (pounding heart at 180 beats per minute, and for over 24 hours), in the comments section I've put some info on side effects and also explain how to make magnesium oil at home - cheaply and easily.
(Note: I turned out to have serious low thyroid and low adrenal function which all doctors and endos failed to diagnose or treat for over 20 years - their so-called gold standard tests are WRONG, yet low thyroid and/or low adrenals are the most common health problem... Low thyroid (hypothyroidism) is being called a silent epidemic (silent because not officially acknowledged) that affects between 40% and 60% of the population. I suggest "Stop The Thyroid Madness" - I think this is the MOST important book and there is also a very helpful website with the same name; both are patient-empowering, detailed and practical - it's basically a how-to manual for low thyroid and also adrenal insufficiency, which is common for low thyroid people. Both website and book explain a quick and easy self/home test for identifying low thyroid in yourself, the basal/morning temperature test, which is the gold standard for identifying thyroid problems (although most doctors don't agree, but then they're not trained to understand thyroid problems - the Broda Barnes Foundation (click on the "Educational Info" button on the left) offers a list of the very few thyroid sympathetic doctors in your state, for a small fee). It's also worth knowing about "The Calcium Lie II" an intriguing book plausibly claiming to explain the root cause of most illnesses.
