PRESERVATION OF DRUGS: There are specific directions for the preservation of homoeopathic drug substances in the monographs of the Homoeopathic Pharmacopoeia of India and other Pharmacopoeias but the general rules are: (1) A container or jar should be properly labelled while preserving a drug in it. (2). All substances should be preserved in natural glass or earthenware vessels or jars, being well stoppered. (3) For corrosive substances, such as acids or alkalies hard glass bottles with glass stoppers should be used. (4). For storing Fluoric acid, gutta purcha bottles must be used, otherwise it may dissolve the glass. (5) Drugs which may be affected by the light or sunlight 'actinic' glass bottles (coloured) covered outside with a solution of asphaltum or black varnish should be used. (6). Avoid blue-coloured container, as blue colour has some on dynamic effects injurious to drugs. (7) Yellow or amber coloured bottles exposed to sunlight (or" sometime, acquire medicinal virtue, so they should be avioded. (8) Keep the container with the medicinal substances away from dust, odours, smoke, moisture, damp, strong light etc. (9) Strong smelling drugs, such as Asafoetida, Camphor, Iodine, Kreosote, Moschus, Terebinthinae, oleum etc. should be kept isolated in tightly closed bottles, so that the peculiar odours of such drugs may not contaminate other drugs. (10) The drug substances should be used for the preparation immediately after their collections. (11) If a fresh drug cannot be used immediately, it must not be allowed to dry; by keeping them in a cold air space. (12) Drugs which are to be preserved for a considerable time may be dried in a chamber , allowing hot air to flow for drying the drug substances. (13) Drugs possessing the power of mutual reaction should be preserved separately. (14) If fresh drugs are to be collected from a distant place, they should be packed loosely and carefully in paper-pulp cases and kept as cool as possible. (15) Drugs which need drying before transportation or preserving, they should be carefully dried by tying in loose bundles, and hanging in a shade away from direct sun light, ram. dust, worms, insects etc. (16) Plants or their parts should be kept in a dry, cool, dustless, odourless place or a little amount of purified (distilled) water may be sprinkled upon them from time to time. (17) For preserving pulverised drugs, they should be perfectly dry, otherwise their moisture content may mould, Their dryings should be made by spreading the pulverised materials on a water-bath, or for a bigger quantities, in a temperature adjustable drying chamher. (18) Animals and animal products decompose very quickly hence they should be used immediate after collections, If required they may be preserved in freeze. Venoms can be preserved in deep freeze being kept in glycerine; or sometime after collections, they are quickly freezed and preserved properly. |
