The medicines prepared in rasashastra will contain number of metals and minerals as
ingredients. They are used after due shodhana, marana and other such procedures which
make them suitable for internal administration. They are prepared or usedeither singly or in
combination with other metal, mineral or herbal ingredients. Most of the cases these
medicines will be reduced to nano particle size.
Anjana (collyrium) is a method of administering medication to the eyes in suitable
form. Number of anjana (collyrium) contain the minerals and metals as ingredient. This
provides a lead to development of nano ophthalmology in Ayurveda. In this work an attempt
is made to collect the information of anjana, which contain one or other mineral or metallic
ingredient. The study could yield 35 formulations as a result of literature search. It is
observed that highest of 16 formulations contain manashila (arsenic disulphide) as ingredient
and rasanjana was present in 14 formulations. Among the formulations included in the study
8 each had sasyaka and gairika, 7 had shankha (conch shell), 6 had tamra (copper), 4 each
had parada (mercury) and haratala (orpiment), 2 each had abhraka (mica), kankshi, loha,
naga, mukta and tankanaas ingredients. Gandhaka, kaseesa, kaparda, vanga, kamsya, rajavarta, vaidhurya, samudraphena and kukkutandatwak were seen in one formulation each.
So, it is imperative to have a thorough safety and efficacy study on these formulations in the
wake of hue and cry about toxicity of mineral medicines. This can essentially help to develop
nano-ophthalmology in Ayurveda.
