Lysine Prevents Growth of Cancer. Dr. Matthias Rath advocates increased consumption of the amino acid lysine (4 ounces daily for a 150 pound cancer patient) as a companion nutrient with vitamin C. Lysine has the effect of blocking the enzymes that dissolve collagen, resulting in encapsulation of the tumor.Read Dr. Rath's book Cellular Health Series Cancer for free on the Internet.

The effect of sulphur species on thiosulphate leaching of gold

The effect of three typical sulphur species tetrathionate, trithionate and sulphide on thiosulphate leaching has been investigated in both pure gold and ore systems. The gold dissolution increased at low concentrations of the sulphur species, but decreased at high concentrations.

How to Clean Tarnished Gold Caused by Sulphur  Our Pastimes

How to Clean Tarnished Gold Caused by Sulphur Our Pastimes

Sulphur can make gold dirty, but it won't damage it. You can clean sulphur off gold in a number of ways. You might need to merely wipe it with a jewelry cloth. However, most gold that is stained with sulphur will require soaking. Remember that the underlying gold won't change color or tarnish. Gold can always be restored to its mint condition.

Sulphur (S) Chemical properties, Health and

Sulphur is a multivalent non metal, abundant, tasteless and and odorless. In its native form sulphur is a yellow crystalline solid. In nature it occurs as the pure element or as sulfide and sulfate minerals. Although sulphur is infamous for its smell, frequently compare to rotten eggs, that odor is actually characteristic of hydrogen sulphide (H 2 S).
