If you have a headache, the doctor prescribes aspirin. The headache disappears and everyone is happy. No one ever asked the question, "What caused the headache?". Based on the treatment prescribed and the resultant "cure", we can conclude that the headache was caused by an "aspirin deficiency."
However, a little research will tell us that aspirin is composed of salicylic acid - an absolute poison to the body. Thus an "aspirin deficiency" is out of the question. In fact, any drug on the market is composed of chemical toxins which are poisonous to humans. How then, can drugs alleviate symptoms, cure ills, wipe out disease and generally make us feel better if they are poisonous?
To understand how drugs "cure" symptoms, let's look a little deeper into how aspirin takes away a pain. Did you know that aspirin will relieve any pain in the body, whether it be a headache or a toe ache? The only exception to this is stomach pain. Aspirin will not help stomach pain. Ask the pharmacist how aspirin works, he will tell you that it has some sort of numbing effect over the entire body, so regardless of where the pain is, it is relieved. But isn't the stomach part of the body? Why doesn't aspirin take care of stomach pain? He will reply that this is one of the great mysteries of aspirin.
Let's say you are out on the farm hunting and you get a thorn in your finger. It is quite sore, so you decide to head back to your truck to get some tweezers to take care of the problem. As you pass through the barn yard, you step on a nail. Do you still feel the pain of the thorn in your finger? In fact, do you even remember it is there? Was your finger suddenly cured when you stepped on the nail? No, not at all. Then why is the thorn no longer a concern? Simply because your body now has a higher priority - something more life threatening to worry about - which is the nail in the foot.
Then as you are passing through the barbed wire fence to finally reach your truck, you shoot your toe off with the shotgun (the other foot of course). Are you now aware of the thorn? No. How about the hole in your foot from the rusty nail? I don't think so. Why not? Once again the body shifted its focus to the most life threatening situation. There is only so much energy in the body. If we create a crisis in one part of the body, energy must be "borrowed" from other parts of the body to cope with that crisis.
Every aspirin (buffered or not) causes a teaspoon worth of bleeding in the stomach. A headache is generally caused by toxic blood from something we've eaten which is harmful to us. So if you have a headache and then take an aspirin, it causes internal bleeding in the stomach. The body must now shift its attention from the headache to the higher priority problem (stomach). This causes the headache to disappear. Did the aspirin remove the toxins from the blood stream? Not at all. It just created a more life threatening situation.
If the aspirin does not take away the headache, it simply means that the internal bleeding is not more life threatening than the toxic blood. So now take six aspirin, which causes even more bleeding, and a more life threatening situation will take place in the stomach. The headache then disappears.
