In India immune disorders are safely treated with mercury preparations by the ayurvedic practitioners since many centuries. The ancient text Rsarnava Kalpa stresses that processed mercury is capable of being used as a drug for the restoration of youthful state as well as curing all diseases which cause degeneration of the body. The essence of living human body is Ojas – the immunity power (resistance of an organism to infection or disease). Ojas enables the stream of life to flow continuously until death. Sexual energy which reaches its highest expression in youth, is the gross counterpart of ojas. The counterpart of ojas outside the body is mercury. Taking processed mercury into the body increases body immunity to fight and win degenerative diseases.  means: “that which takes you to the other shore of life; that which grants enlightenment and freedom.” By utilizing therapeutic mercury it is possible to overcome all diseases; maintain youth and vitality; prolong life indefinitely; and unveil all mysteries related to birth, death, the cycle of transmigration, and the relationship between the microcosm and macrocosm.According to Ayurvedic texts, 18 steps are required to purify mercury. Of these, only the first 8 are recommended for medicinal purposes and commonly practiced by Ayurvedic physicians. The remaining ten steps, which are obscure and used only for purifying mercury in such a way that it can transform vulgar metals into gold. Ancient texts such as Rasa Ratna Samuccaya, Rudra Yamala, Goraksha Samhita, and the Hatha Yoga Pradipika touch on the subject, but only enough to arouse our curiosity.In Ayurvedic tradition, cinnabar is considered to be the precursor of the Amrita (elixir of immortality); the combination of mercury and sulfur in cinnabar has metaphysical significance. In isolation mercury is a liquid. It is the sulfur in cinnabar that keeps mercury in place. Thus, the relationship between mercury and sulfur is like that of Shiva and Shakti, pure consciousness and the force of creativity, respectively. Ayurvedic processing of mercury is very elaborate and Western scientists are not fully aware of it. It is a unique traditional art of transmutating toxic heavy metal in to non-toxic light metal. Ayurvedic texts describe how to make mercury sweat (svedana), how to massage it (mardana), how to make it faint (murchhana), how to lift it (utthapana), how to drop it (patana), how to awaken or educate it (bodhana), how to control or discipline it (niyamana), and how to energize it (depana.) Although following these 8 steps is a long and tedious process, Ayurvedic specialists maintain that only such purified mercury is fit for medicinal preparations.
A project for Physico chemical characterization and toxicity studies of 8 widely used Bhasmas (including Mercury) was sanctioned by Department of Ayush, Government of India which is being carried out by various laboratories of CSIR i.e. Indian Institute of Toxicological Research (IITR), Lucknow, Indian Institute of Chemical Technology (IICT), Hyderabad. Under this project, one of the reputed manufacturers of Rasa Aushadhies was chosen for manufacturing of the selected Rasa Aushadhies as per the classical texts which were made available to CSIR laboratories for physio chemical characterization and their toxicity studies. On the basis of 28 days toxicity studies, all the 8 Rasa Aushadhies have been found to be non-toxic. 90 days chronic studies are under progress. CSIR would be getting the results of this scientific research published to set at rest doubts regarding the safety of Mercury preparations prepared properly as per classical texts. The symptoms of mercury poisoning include dizziness, loss of memory, low energy, degeneration and even death of bodily tissues. Ayurveda regards processed mercury as the master medicine for all diseases, including above symptoms. This seems to be in line with the homeopathic principle that similar cures similar, is not it?
