The effects of microdoses have been known for a long time, and there are a number of examples that support the idea that very diluted concentrations of a substance will have a measurable and sometimes profound effect. Scientists call this phenomenon : hormesis.
Scientists from Michigan State University have shown how hormesis work in nature. They used microdoses of a fertilizer to stimulate crop production. In a dose equivalent to a 9x dilution, the fertilizer increased tomato yield by 30 percent, carrots were 21 percent bigger, and corn yield increased by 25 percent.
Our own bodies secrete minute amounts of hormones that have powerful effects. Thyroid hormone is present in our blood at only 1 part per 10 billion-yet this is enough to regulate the rate of our entire metabolism. Many animal studies show that low doses of some substances elicit a beneficial response while high doses are harmful. This phenomenon has been documented to occur with radiation, antibiotics, and heavy metals.
Pheromones
Pheromones are powerful aromatic hormone-like substances that creatures secrete to attract one another. One molecule of moth pheromone is so potent, it will attract another moth from miles away and trigger a cascade of physical reactions. Though well documented, the exact mechanism for pheromones remains unknown.
