Caesium is a hitherto unknown remedy. It can’t be potentised in its metallic form, because it is highly reactive with water.
The name is derived from the word ‘caesius’, meaning sky blue. The salts give off a blue flame when oxidised. It was discovered in 1860, its chemical symbol is Cs.
Caesium is a soft, light metal with a golden yellow sheen. It is highly reactive and melts at 28 degrees Celsius. It is used in vacuum tubes, atomic clocks, photo-electric cells, scintillation counters and in the glass industry.
