* जिंक metal is included in most single tablet over-the-counter daily vitamin and mineral supplements. It is believed to possess anti-oxidant properties, which protect against premature aging of the skin and muscles of the body. In larger amounts, taken as जिंक alone in other proprietaries, it is believed by some to speed up the healing process after an injury. Preparations include [[जिंक acetate]] and [[जिंक gluconate]].
* [[जिंक gluconate glycine]] and [[जिंक acetate]] are also used in [[throat lozenge]]s or [[tablet]]s to reduce the duration and the severity of cold symptoms.<ref>Ananda S. Prasad, MD, PhD; James T.

=== Popular misconceptions ===
The highly characteristic metal [[Bar (counter)|counters]] of traditional [[France|French]] [[Bar (establishment)|bars]] are often referred to as '''जिंक bars''' or vaguely '''जिंक''', but actually जिंक has never been used for this purpose and the counters are really made of an alloy of [[lead]] and [[tin]].
 
== इतिहास ==
प्राचीन भारतय् जिंकयु शोधनज्या सिक्क हे येक्व जुगु खने दु। Many mine sites of [[Zawarmaala]] were active even during 1300-1000 BC. There are references of medicinal uses of zinc in the [[Charaka Samhita]] (300 BC). The [[Rasaratna Samuccaya]] (800 AD) explains the existence of two types of ores for zinc metal, one of which is ideal for metal extraction while the other is used for medicinal purpose.<ref>http://metalrg.iisc.ernet.in/~wootz/heritage/zn.html</ref> Zinc alloys have been used for centuries, as brass goods dating to [[1000s BC|1000]]–[[1400s BC|1400 BC]] have been found in [[Israel (region)|Israel]] and zinc objects with 87% zinc have been found in prehistoric [[Transylvania]]. Because of the low boiling point and high chemical reactivity of this metal (isolated zinc would tend to go up the chimney rather than be captured), the true nature of this metal was not understood in ancient times.
