Substitute:


Turquoise (Unani)

Main Combinations:


1. Cardiac stimulant, and for Depression and Hypertension, with Tabasheer, Serpentine, Oyster shell, Green Agate, Ambergris (as in Sufuf Fizzah of Unani)
2. Sexual Debility and Premature Ejaculation, with Saffron, Skink, Nutmeg, Cuttlefish bone, Musk, Serpentine (as in Pills of Nishat of Unani)

Major Formulas:


Medicine to Defend the Base from all Danger
Pills of Nishat (Unani)

Cautions:


1. The metal in non-toxic, but some of its salts are toxic.
2. Long-term use of Silver salts can lead to chronic skin discoloration. The salts were not used for more than a month or two without a break.

Toxicity:


Tissue distribution and acute toxicity of silver after single intravenous administration in mice: nano-specific and size-dependent effects
In vitro intestinal toxicity of commercially available spray disinfectant products advertised to contain colloidal silver

Main Preparations used:


Leaf, Bhasma, various Salts. In modern times, Colloidal Silver has gained popularity.

‘It is Cold and Moist, and Cephalic, and therefore is said to strengthen the Head, and by cheering the animal Spirits, resists all diseases of that part, chiefly the Megrim [Migraine], Apoplexy, Epilepsy, &c.’

The tincture is used for Epilepsy, Apoplexy, Vertigo, Lethargy, Migraine, Palpitation, Madness, Melancholy, by comforting and strengthening the Brain. It has the virtue of the Tincture of Gold, but
not so strong. The Calx prepared by dissolving in Nitric acid and washing well has similar virtues.

The Amalgamation (made with equal parts of Silver filings and Mercury) is reduced to powder. Used as a plaster it relieves pain of Gout. The powder applied to Ulcerated Cancers has been known to cure them as well as other stubborn Ulcers and running Sores. (Salmon, Seplasium)
