Gandhaka rasayana for the treatment of Mercury poisoning:
In ancient times, Vaidyas preparing Purified Mercury containing medicines, called Rasaushadhis were taking Shuddha Gandhaka – purified sulfur continuously. They new that
Mercury is volatile and can enter into body even with inhalation
Impure Mercury is toxic and hence the need for purification before administration.

Hence, many Ancient text books advise to administer Gandhaka (Sulfur) containing medicines to people who work with Mercury.

While discussing mercury poisoning, Dr Hymen states as below –
“The only way it can get out of your body is via urine, feces, expired air, and breast milk. The major reason it is toxic to human biology is because mercury has the ability to bind to sulfur-containing molecules in the body (found in nearly every enzyme and in the mitochondria), as well as other chemical binding sites in the cells.”

“The only way to find out your total body load of mercury is to take a medication with sulfur molecules that binds to the mercury like fly paper.”

Hence, the ancient Vaidyas were right in using Shuddha Gandhaka on themselves and also administering Gandhaka containing medicines in case of Mercurial poisoning.

Gandhak rasayan is a very good way of taking Sulfur.

Another point is,
If you analyse Purified Mercury containing Ayurvedic medicines (called Rasa Aushadhis), 99 % of them have purified Sulfur as an ingredient.
Makaradhwaja – used as heart tonic, aphrodisiac and immunity booster
Shwas Kas Chintamani Ras –  used in the treatment of respiratory diseases

I am not indicating that it is the specific antidote for Mercury poisoning. But if you have suffered from Mercury poisoning, it makes sense to talk about Gandhaka Rasayana with your Ayurvedic doctor for its prescription.
