What is black Mercury?
The potent properties of mercury are stabilised by its trituration with ‘sulphur’ (gandhaka) which has a natural affinity to form a unique compound with mercury through a grinding process. This triturated black compound made of ‘purified’ mercury and sulphur is black mercury sulphide called kajjali.
Can you touch mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways.
