Unfortunately, in most modern methods of using books and dose mumiyo from ancient sources.
It would seem, what's the difference? And it is that in the last decade, ranging from approximately 40 - 50 years of the last century, radically changed the power supply system, as it makes no sense to repeat.
In those days, when installed intake will mumiyo, all the food on earth was organic, contained a complete set of trace elements.
Therefore, people who are sick enough to be taken in small doses mumiyo and short courses that could positively affect the course of the disease.
Now that the organic food is almost nonexistent on the ground, and a small amount of it is grown specifically for very rich people, trace element "failure" is becoming a huge problem for the vast majority.
However, they can use mumiyo which contains trace is identical to that should be in the food.
Intake will be set individually. Generally, they are designed, first, to fill trace element deficiency, open to everyone from birth. Then remain maintenance doses, preferably for life as it was defined before the period of agrarian nature of the "revolution" that destroyed the organic food and most of our health.
Healthy people is desirable to use a regular small doses mumiyo, if you understand that it is an integral part of the food that gives us life and health.
And the few people today who feel relatively healthy organic food without additives and micronutrients, just got a natural "stock" strength more than others. But even he has a limit, which, in my opinion, there is no sense in pushing when there is a simple and sure way out, given the nature.
