CONCEPT OF BHASMA ALONG WITH RECENT ADVANCEMENT Herbs were widely used for medicinal purposes from the ancient past. Gradually minerals were also identified and incorporated for medicinal purposes. For making fine powder heating, quenching in various liquids, grinding and filtering through cloth were adopted. Later along with these techniques, many other specialized processing techniques like Shodhana (purification), Marana (incineration / calcinations), Samskara (specialized processing techniques specially used for mercury) etc were also developed. With the advent of processing techniques of Rasa Shastra, use of metals and minerals came frequent in therapeutics. 1. Rasa: Parada (Mercury) 2. Maharasa: Abhraka (Biotite), Makshika ( chalcopyrite), Vaikranta (blackturmaline) etc 3. Uparasa: Gandhaka (S), Gairika (Red heamatite), Manahshila (As2 S2), Haratal (As2 S3) etc. 4. Sadharanarasa: Gauripashana (Arsenic oxide), Hingula (HgS), 5. Dhatu: Gold, Silver, Copper, Iron, Lead, Tin, Zinc etc 6. Ratna: Ruby, Diamond, Emerald, Topaz etc gems. 7. Marine products: Pearl, Coral, Shankha, Shukti, Varatika etc. Small dosage, Tastelessness, Quick absorption and effectiveness, Long self-life, Wide range of therapeutic efficacy, Effective on dreadful chronic and incurable diseases. Easy storage and Easy transportation. Above such qualities of mineral preparations made them popular and superior over the herbal medicine. In general practice simple diseases are treated with herbs or herbal formulations where as chronic and dreadful are through Rasoushadhi 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Heating, Heating and quenching, Boiling with various liquids (swedana), Grinding (mardana), Roasting (bharjana), Filtering (galana), Distillation (patana), Sublimation (urdhwapatana), Wet trituration (bhavana), Heating through puta or kupi paka system. Above are the important procedures applied during Shodhana and Marana. 1. 2. 3. 4. 5. 6. 7. 8. 9. Shuddha dravya, Bhasmas, Sindura, Pottali, Parpati, Druti, Drava, Satwa bhasma, Kharaliya Rasayanas Above are the products of mineral material. With the combination of these above innumerous formulations are derived. 1. 2. 3. Pre treatment: Shodhan (Purification) Main / chief treatment: Marana (incineration /calcinations), Postoperative treatment: Lohitikarana, Nirutthikarana and Amritikarana. For the production of Bhasmas, Shodhan (Purification / Pretreatment) and Marana (incineration /calcinations), these two fold procedures are the important steps (including some intermediary procedures in respect of particular materials like Dhanyabhraka for Abhraka and jarana for lead, tin and zinc). Shodhana is an addition and separation process, it is a pre process for marana. Following effects are observed during Shodhana, 1. 2. 3. 4. 5. 6. Material becomes free from visible and invisible impurities. Undesirable volatile and inflammable material escapes out. Masses of minerals converted into fine and brittle. Development of fineness and brittleness facilitates the bhavana process. Partial oxidation and reduction takes place. Induction of organic therapeutic property in the inorganic material It is a wet trituration process; Advantages of Bhavana are following, 1. 2. 3. Materials are mixed uniformly Materials divided into fine. Surface area of material exposed and expended which facilitates reaction during firing (Marana) 4. Develops softness, smoothness and stickiness in the material facilitates better binding of material. 5. Enhances the therapeutic property of minerals and metals. 1. Small disk of Bhavita material should be made. 2. Its diameter should be of 3’ CM and thickness of ½ CM. 3. Dry in sun or in dryer Drying of pellets: 1. Before putting it in Sarava (casseroles) for sealing it should be dried completely. 2. Wet pellets should not be allowed. 3. Wet pellets if subjected for firing (puta) desired colour will not appears. 4. Desired smoothness will not develop. 1. Arrange it 1- 3 layer in a earthen casserole 2. Covered it with another casserole 3. Joints of earthen lids should be sealed 3 to 7 layers with cloth and mud 4. Again dry it in sun or in dryer. 5. Properly sealed prevents the escape of volatile material. 6. It prevents interference of out side gases and dirt. Finally sealed casseroles subjected to puta system of repeated heating till the material completely converted into bhasma with desired characteristics. 1. Marana term denotes the meaning of incineration or calcinations. When minerals (compounds) and metals (elements) are subjected for heating on moderate to intense temperature, compound material converted to certain other compounds where as elements get reduced to certain compounds. 2. Nature of compound depends upon the material added in to the main material and exposure of environment. 3. Various system of heating is applied for this purpose but the puta system of heating is common for marana. 4. Marana is an Association and dissociation process. 5. Elements are converted into certain compounds 6. Metals are reduce to ash (forms compound) 7. Compounds are converted into certain other compounds. 8. Nature of compound formed depends upon the material used for marana. 9. It may be sulphide, oxide, chloride, sulphates etc. 10.Macro forms of material converted into micro form, 11.Heavy and solid material converted into light and soft. 1. Puta is a specific system of heating for the incineration metals and minerals. 2. For the hard, soft, organic, inorganic, volatile, inflammable and according to heat resistance various puta have been described. 3. According to the quantity of fuel Mahaputa, Gajaputa, Varahaputa, Kukkutaputa, kapotputa, Gorbarputa, Bhanda and Tusha etc puta are mentioned. 4. Each and every puta have different diameters. 5. Intensity of heat, Mode of Temperature and Time duration depends upon the puta. 6. According to the heat resistance of the material puta are selected and applied for the marana purpose. Such as, for Gold & Silver Laghu or Kapot puta, Vanga, Naga, Yashada Kukkutaputa or Ardha gajaput, Tamra in Varaha or kukkutaputa and for Abhraka and Loha in Varaha or Gajaputa are applied. Effects of puta, 1. 2. 3. 4. 5. 6. 7. Puta is an unit of quantum of heat (to be applied for the marana of material). Puta removes the blemishes (dosha vinash) and Exposes the therapeutic quality (gunodaya) of the\ material. Metals (elements) are reduced to ash (converted into compounds) Compounds are converted into some other suitable compounds. Material becomes light, fine, smooth and non reversible. Materials are converted into Bhasma (suitable therapeutic forms). Each and every puta have different diameters. According to size of pit quantity of fuel accommodated in it. Quality and Quantity of fuel is responsible for the production different intensity of heat for particular duration. Selection of puta is based on the chemical nature of the material to be taken. Intensity and duration of temperature depends upon the size of puta. Selection of putas depends upon the chemical nature (volatile, inflammable etc) of material. and heat applied. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Mahaputa Gajaputa Varahaputa Kukkutaputa Kapotaputa / Laghuputa / Lavakaputa / Gorbaraputa Bhudharaputa Bhandaputa / Balukaputa Vastraputa Sutraputa, Suryaputa Chandraputa (Post operative Specific treatment): 1. 2. 3. Lohitikarana, Nirutthikarana and Amritikarana In some cases post operative procedures are also followed to achieve safe, effective and desired Bhasma. Amritikarana: 1. 2. It removes the remaining blemishes of the bhasma and It enhances the therapeutic properties of the bhasma. Lohitikarana: 1. It develops desired red colour in case of loha and Abhraka bhasma. Nirutthikarana: 1. 2. It reduces remaining free metals of the bhasma. It convert the metals into complete bhasma. Rasaushadhies are mainly based on minerals (compound state) and metals (elemental state). The basic material when treated frequently with plant extractives and heated on fire the following reactions are observed. 1. Marana is a compounding / reduction and dissociation process. 2. Plant extractives are converted into ash or solid organic / inorganic forms depend upon the intensity of heat applied. 3. Compounds are reduced and converted into another compounds. 4. Elemental metals gradually reduced and converted into compounds. 5. Nature of compound depends upon the media as catalyst added. 6. Herbal residue participates in formation of compound or it may present with the mineral compounds. 7. Wet grinding after each firing exposes the surface of metallic particles. 8. Exposed surface coated with the media of catalysts for further reaction. There are many testing parameters, through which product can be judged, 1. Physical – a. Rekha purnatwa (indicative of fineness), Varitaratwa (lightness), Nishchandratwa (free from metallic luster), 2. Chemical – b. Apunarbhavatwa and Nirutthatwa (complete conversion into non reversible compound / absence of free metal in bhasmas) c. (tastelessness), Dadhi / Amla parikshaas for Tamra or Tamra containing metals (indicative of absence of free metallic radicals in the bhasmas), Colour of various Bhasmas i.e. Swarna - Champaka varna (reddish yellow colour) , Rajata and Tamra - Krishna varna (black), Vanga – Sweta varna (white) etc. Kamsya – Dhusara. Naga – Kapot varna. Teekshna loha – Pakwa Jambu phala varna. Abhraka – Istika varna (brick red colour). These testing parameters are essentially followed for the determination of Bhasmas on process as well as on product level. 1. 2. 3. 4. 5. These tests are time tested and perfect but these essentially based only on naked eye observation and experience. They have limited sensitivity and can be applied only after long experience and practice. With the advent of modern science and technology many other sophisticated and sensitive tests are being employed for ascertaining the standards of the Bhasma prepared. These include Metallographic study, Spectrophotometer, Scanning electron microscopy (SEM), XRD, Atomic Absorption Spectrophotometer, Particle size analysis etc. The analytical study of metallic bhasmas reveals that physical and chemical changes take place after each and every process. Hence chemical analysis on the level of ash content, acid soluble / insoluble content, moisture content, specific gravity, loss on ignition, loss on drying etc. should be determined. For the grinding, powdering, filtering, heating, drying various new machines are presently utilized, such as 1. 2. 3. 4. 5. 6. Grinder (mortar & pestle) End runner / Edge runner Disintegrator / Pulverizer Sheave shaker / shifter Dryer / drying ovens Electrically/ petroleum oil and gas heated muffle furnaces To save the manual labor, prevention of pollution, bulk production and ultimately for the better result these devises are the need of the time. Details their working performance and output should be established, drying, heating are the important steps hence before shifting on them temperature pattern should be understand and then these can be utilized. 1. Selection and authentication of raw material, 2. Application of standard procedural methods (various procedural steps) 3. Use of essential equipments and utensils, 4. Uses of various heating devices (various putas / electric muffle furnaces) or system are applicable for particular material, 5. Intensity of temperature required / to be applied, 6. Application of testing parameters to achieve desired characteristics in the Bhasmas, 7. Application of post operative Samskaras to the Bhasmas wherever needed. 1. 2. 3. 4. 5. Earlier medicines were prepared by the physician themselves for their patients. The physicians were well qualified to identify the materials. They were trained in various processing. They were following guidelines of Shastra and experienced teachers. According to the immediate need of the patients they were modifying the formulations as per their occupied understanding. 1. 2. 3. Physicians today are more involved with diagnosis and treatment. The drug manufacturing has gone into the hands of businessmen. The crude drugs are mostly in the hands of shopkeepers who supply them to the pharmaceutical industries. 4. They are using their own methods. 5. In large-scale production they compromised with quality and quantity of material. 6. Compromised with longer and lengthy procedures. 7. The drugs added during procedure are not mentioned on the label. 8. Equivalent substitutes are added in the compounds are not validated. 9. The exact important procedures either altered or made shortcut 10. This led to the decline in the quality of Ayurvedic drugs. 11. The standardization of Ayurvedic drugs is thus felt necessary Vanga Bhasma 1. Bhasmas & kupipakwas of minerals, metals and mercurials were prepared earlier through the manual trituration and conventional heating. 2. These two, trituration and heating are important factor with respect to safe and effective products. 3. Trituration makes material fine and heating converts them into suitable compound form. 4. During trituration greater surface of particle is exposed, resulting in better contact of other material added during process which reacts with the exposed surface and convert them into suitable compounds. Continuous trituration is not possible manually since it is difficult, laborious and time consuming. It can be made easy by mechanical process. Hence, trituration and grinding for bhavana should be shifted to machines. It is beneficial as well as easy to achieve the desired particle. It can be determined with the help of particle size analyzer. Fine particle can be absorbed easily by the system. For the preparation of bhasma and kupipakwa, application of desired temperature and time is essential. For Bhasma, Puta method and for KupiPakwa, Valuka Yantra method is in practice. In puta method, cow dung cakes are mostly used as fuel material. In some cases, firewood, goat dung is also used. The temperature value and duration depends upon the quality and quantity of fuel. For applying Puta with the fuel, various sizes of pits by the name MahaPuta, GajaPuta, VarahPuta etc have been mentioned in the text and is in practice. After long observation and detail studies, the Puta system is shifted to Electric Muffle Furnace. With respect of land, labor, capital and quality of yield, this system has proven to be advantageous. Various commercial houses have adopted this system due to its easy control system too. Temperature patterns applied in different puta’s are shown in the graph. Temperature (in C) 1200 1000 800 600 400 200 0 0 2 4 6 8 10 Time (in hours) MahaPut GajPut KukkutPut VarahPut LaghuPut BhudharPut 12 Temperature (in C) 500 400 300 200 100 0 0 5 10 15 20 25 Time (in hours) GorbarPut BhandPut BalukaPut 30 Most of the products, including their intermediary samples have been studied chemically, as well as physically i.e. Metallographically & XRD levels. Metallographic technique was found advantageous in determining the presence of free metal in bhasmas. This technique is considered as an advancement of Nirutha Pariksha of metallic bhasmas. Toxicity evaluation of all the materials along with their final products have been done to rule out their toxic effects on various vital organs at acute, sub acute, and chronic levels in variable doses and found to be nontoxic in therapeutic doses. Drug manufacturing is a skill full art. Neither less nor excess processing / cooking is beneficial. Only supakwa (properly cooked) is beneficial and desirable. In fact the minerals and metals of industrial importance are identified on global level. Their data and values are available. But the Ayurvedic compounds based on minerals and metals and prepared by ancient classical methods are yet unidentified. It is due to their nation wide limited use Bhasmas and sinduras are safe when prepared and used properly. Use of bhasmas and sinduras when prepared in Improper and short cut ways, can prove injurious to health Ayurveda and its medicines are serving the needs of ailing humanity since many centuries. Particularly bhasmas and sinduras have good preventive, curative and rejuvenating potential. There is a need of systematic and well-organized coordination of allied sciences along with adequate infrastructure and facilities to solve various problems related to the standardization of Ayurvedic drug / Rasaushadhies / Metallic bhasmas. This may facilitate the development this discipline and lead to its global recognition. Discovering new knowledge about products, processes, and services, and then applying that knowledge to create new and improved standard products, processes, and services that fill market needs. •Level of research in Ayurveda in India and at International level is not up to the mark. •Format and Protocol of Ayurvedic researches are not adequate. •Financial support for Ayurvedic researches from different sources is very meagre. •Moreover the standardization of the ingredients in Ayurvedic formulations itself is a biggest challenge. Available Research initiatives in India for Ayurveda • Ayurvedic Post Graduate teaching institutions private, Govt. aided and Government. • Central Council for Research in Ayurveda & Siddha. • Modern Research Institutions of Govt. of India like CSIR, ICMR, ICAR, CDRI, ITRC, NBRI, CIMAP etc. • University Faculties – Dept. of Botany, Biology, Pharmacology, Medicinal Chemistry etc. • Pharmaceutical companies as a part of their R & D • NGOs like FRLHT (Bangalore) CCRAS-Central Council for Research in Ayurveda & Siddha ICMR-Indian Council for Medical Research CSIR-Council for Scientific & Industrial Research DST –Department of Science & Technology DBT –Department of Bio-technology BHU, AIIMS, NIMHANS Golden Triangle Initiative (GTP) of AYUSH, CSIR & ICMR International Research Establishments Following organizations in foreign countries are engaged in researches •on therapeutic aspects of herbs and their extracts used in Ayurveda are being published in Western Journals occasionally. •World Health Organization (W.H.O.) •National Center for Complimentary and Alternative Medicine (NCCAM) •University of Texas Center for Alternative Medicine Research. •American Botanical Council At International level especially in US & UK various Universities and medical schools few scientist are conducting researches on herbs used by Ayurveda as CAM / Alternative medicine What we can do for better establishment of R&D and QC Department.

Efficacy without safety is useless. Hence, efficacy and safety has to go hand in hand at all levels. Safety evaluation should be based on internationally accepted guidelines. Safety of drug should be evaluated on different species of experimental animals in variable doses and time duration. Acute, sub-acute, and chronic physicopathological variations should be estimated biochemically and histo-pathologically. Efficacy should be evaluated on various pharmacological, as well as clinical parameters. Prof. Siddhinandana Mishra Prof. C.B Jha Prof. Kamadev Das Dr. Sathyanarayana Bhat Dr. Prabhakar Ranjal Dr. Ravindra Angadi It was observed in the studies that the difference in temperature between, out side and inside the Samputa is about 100 degree C. In Kupipakwa method, many compounds are derived. Each material and their products have different nature; hence temperature pattern varies according to product, as shown in the graph. In Kupipkwa preparations, temperature and time both are important and it can not be overlooked. In case of Sagandh Kupipakwa, contact of mercury and sulphur for longer duration is belived beneficial with regards to efficacy. But for the formation of Rasasindura (Red Sulphide compound) 6 to 8 hour’s duration is sufficient (Rasa Sindur Pak Kalagni Vinischaya, Dr H.S. Sharma .et al in 1976). Time may vary according to the quantity of sulphur taken. In case of Rasa Karpur and Swarna Vanga temperature pattern will be changed, as shown in the chart.
