Here is a updated summary of my view on distilled water:
1. Long term used of distilled water is not healthy
2. Distilled water only short term use may help detoxify, but never use more than for a couple of days.
3. Distilled water depletes the body of bicarbonates, causing metabolic acidosis in the long run.
4. Some people use medicine added to distilled water to help absorption. This doesn't work for me because you are going from a lower concentration of distilled water to a higher concentration blood. Hence, more concentration of blood would not help absorption.
5. In Traditional Chinese medicine, and I agree, adding a small amount of salt (e.g. preferably sea salt) helps absorption of medicine better then without. The body absorbs substances along the intestinal lining using a mechanism called the sodium pump mechanism. Therefore, if there is sodium along with the supplements, they are then pumped into the body, thus increasing absorption. This is also a long recognized practice in traditional chinese and traditional based medicine.
Additional Information NOT mentioned previously are:
1. Sea salt is the best detoxification as it corrects electrolytic imbalance
2. Sea salt solution generally works better then distilled water.
3. Allergies in general is best handled with a sea salt remedy. For example 1 teaspoon per glass of water. A distilled water may not work.
4. Most of the toxicity of drinking water we have today is from tap water with free metals that is causing the problems. Most tap water have this problem because of our faucets and old pipe plumbing. Hence some people thinks distilled water works better. In practice a bottled or mineral water will work better because, the manufacturers don't generally have any free metals due to stricter standards.
5. Some people who tries to avoid all the water by drinking a close alternative, Reverse Osmosis water, won't have the problem of free metals, and is close to distilled water. To restore some of the naturalness of water, a sea salt of 1/4 teaspoon and perhaps 1/8 teaspoon of baking soda is very helpful. I have found that the major source of magnesium in humans mostly come from our drinking water supplies, but this may need to be supplemented on occasion too.
