| Description: | 53 t\={a}mram\={a}ra\d{n}a procedures, as well as 204 rasayogas indicated for \'{s}v\={a}sa, described in rasa\'{s}\={a}stra texts were studied; this revealed that 106 out of the 204 rasayogas contain copper (t\={a}mra); it was decided to carry out t\={a}mra\'{s}odhana (purification of copper) in agreement with the prescriptions of the Rasaratnasamuccaya; 2 kg of copper wires used in electric motors were subjected to general and special purification in bulk; a total of 540 gms of copper was lost due to the fact that the fine copper powder formed in the process was mixed homogeneously in the liquid and was very difficult to collect completely; the purified copper was subjected to m\={a}ra\d{n}a in three different ways, selected with a view to the purity of the media: (1) purified copper (1 part), purified mercury (2 parts), sugar (1 part), trituration with lemon juice, three pu\d{t}as, (2) purified copper (1 part), purified sulphur (2 parts), gha\d{t}\={\i}yantra process, (3) purified copper, juice of Solanum virginianum Linn. = S. xanthocarpum Schrad. et Wendl., trituration, three pu\d{t}as; process 1 was unsuccessful, the type of pu\d{t}a was not indicated in the texts, the bhasmapar\={\i}k\d{s}\={a} test gave negative results in the curd test (which indicates the presence of free copper); process 2: 300 gms of purified copper powder and 600 gms of purified sulphur were used, after ten hours of heating on a gas stove t/=amrabhasman was obtained in a high yield (initial weight 300 gms, weight of the final product 413 gms), allowed to cool and subjected to par\={\i}k\d{s}\={a}, which gave a positive result, but subjecting the bhasman to am\d{r}t\={\i}kara\d{n}a gave an exexpectedly bad result, which made it necessary to correct the bhasman by using the original method of t\={a}mram\={a}ra\d{n}a (the article does not specify how this was done); process 3: as a medium for m\={a}ra\d{n}a only the Solanum juice was used, three pu\d{t}as are prescribed, but after subjecting the product to three gajapu\d{t}as it did not fulfill the criteria on bhasmapar\={\i}k\d{s}\={a}, subjection to three more gajapu\d{t}as, two ardhagajapu\d{t}as and one laghupu\d{t}a made it meet the requirements, an attempt at improving the quality by am\d{r}t\={\i}kara\d{n}a was futile, which led the authors adopt the original method (which one is not clear) of triturating with Solanum juice and application of pu\d{t}a, six pu\d{t}as made the product stand the bhasman test, but the yield was rather poor (initial weight 400 gms, weight of the final product 280 gms) and the time required long (30 to 45 hours if carried out continuously without break; the authors do not indicate the number of pu\d{t}as during this long time); the bhasman was tested on 24 patients; 17 received bhasman 2, 7 patients bhasman 3 (dose: 125 mg with honey thrice a day) during 21 days; good symptomatic relief was obtained in both groups (96.32\% in the first group, 90.87\% in the second group); the patients of the first group recovered much more speedily than those of the second group; process 2 proved to be the most economical one to produce t\={a}mrabhasman; instead of the traditional way of using gajapu\d{t}a in cases where the type of pu\d{t}a is not indicated, the authors advocate to use c\={u}lhik\={a}gni |
