"Transmutations of the elements is a routine and daily process in all living forms, including human beings. ... A biological process is necessary to complete a give n transmutation. Physicists and nuclear chemists ... thus far failed to achieve [it] in a lab except by high energy particle acceleration or extreme temperatures. The dream of "cold fusion" - nuclear exchanges at low temperatures - has never been accomplished in a laboratory, even though millions of dollars and many years of research have been expended toward the effort by many scientists. The difference is the presence of life.
The laws of physics and chemistry do not apply to living processes the same way they do to the dead processes of a lab or to the inorganic world around us."
Examples of transmutations are:
12Mg + 8 O = 20 Ca
14Si + 6 C = 20Ca
Calcium Is Not Always the Asnwer
..."For centuries it has been known by herbalists that regular intake of horsetail helps prevent bone loss and will speed up the repair of broken bones. Yet horsetail contains little or no calcium.
What it does contain is rich amounts of silica. Apparently, the Si atoms in horsetail can be converted into Ca atoms by the body.
However, the body cannot transmute just any old silicon into calcium. In fact, ingesting inorganic silicon will cause decalcification of the bones.
Natural sources of both Si and Mg, such as various herbs, have long been known for their benefits in other bone and joint ailments, such as rheumatism, osteoporosis, and arthritis. A diet rich in calcium does not necessarily strengthen bone or repair joints or build teeth. Children on normal diets, including calcium-rich milk and cheese, have been known to suffer delayed dental growth until placed on diets of fruits, meat, and vegetables (with no dairy products). Within weeks, their tooth development was restored to normal.
Fresh green leafy vegetables contain significant amounts of silicon. In fact, cows excrete more calcium than they ingest and can live on a diet of various grasses rich in silicon and poor in calcium.
Another secret to healthy calcium content in your body is magnesium (Mg). Magnesium is the core element around which the chlorophyll molecule is built. Eating any green vegetable is consuming magnesium.
