Shukti is an important component of Sudha Varga, which is considered as the latest class in the field of Rasa Shastra. Two types of Shukti have been mentioned in Rasa Shastra texts i.e. Jala Shukti and Mukta Shukti according to the availability. In present study, an attempt has been made to develop a standard manufacturing procedure (SMP) of Jala Shukti Bhasma and Mukta Shukti Bhasma. Five batches of Jala Shukti Bhasma and Mukta Shukti Bhasma were prepared and standardization was attempted by maintaining batch manufacturing records of individual batches. During pharmaceutical procedures like Shodhana, Bhavana, Marana, etc. due care of temperature, its duration, percentage of weight gain or loss and the cost factor of the end product, etc. were considered. The average weight loss observed was 12.08 g i.e. 2.42% and 14.62 g i.e. 2.92% during Jala Shukti and Mukta Shukiti Shodhana respectively. Average weight loss found was 38.94 g i.e. 7.79% in Jala Shukti Bhasma while in Mukta Shukti Bhasma, it was 35.24 g i.e. 7.05%. At the end of the pharmaceutical procedure, it was found that Mukta Shukti Bhasma is 2.8 times costlier than Jala Shukti Bhasma.

Rasashastra is a branch which deals with the pharmaceutics of Rasaoushadhis. Bhasmas are one among such Rasaoushadhis which are known for their low doses and fast action. A verse from Rasaratnasamuchchaya says that the bhasma prepared by using Mercury as media is of best quality.
Materials and Methods:
Following this principle, Yashadabhasma (Zinc calx) was prepared by subjecting it to Samanya shodhana (general purification method for all metals), Vishesha shodhana (specific putification method for Zinc), Jarana (roasting) and Marana (incineration) with Parada(Mercury) as a media under Gajaputa (classical heating system with 1000 cowdung cakes).
Results and Conclusion:
Yellow colored Yashadabhasma which passed all the classical bhasmaparikshas (tests for properly prepared calx) was obtained after two putas. The bhasma did not pass Nishchandratva(free from shining particles) test after 1stputa but was passed after giving it 2ndputa.

Lauha Bhasma is the most widely used bhasma preparation in therapeutics, but till date the temperature pattern to prepare Lauha Bhasma in electric muffle furnace is not fixed. So in this pilot study an attempt has been made to confirm the appropriate temperature pattern to prepare Lauha Bhasma. And emphasis has been given to evaluate this prepared Lauha Bhasma on classical analytical parameter, which reflects the physical and chemical properties of the Bhasma.
Tamra Bhasma (incinerated copper) is one of the main weapons in the archery of Ayurvedic practitioners. Though several methods of preparation of Tamra Bhasma (TB) are found in Rasashastra classics, several difficulties occur during the preparation of a good-quality Bhasma. In this study, TB was prepared and analyzed to develop the standard manufacturing procedure. Each unit operative procedure was considered as an independent processing and an attempt was made to validate each procedure. Wire used for the purpose of electrical earthing was taken for the preparation of Bhasma. Procedures of Shodhana, Marana, and Amritikarana were followed as per the classical references. Specific temperature pattern was adopted for Puta in the electrical muffle furnace. From 500 g of Tamra, 483.4 g of black colored TB was obtained after subjecting to three Putas. Final product was detected to be cupric sulfide in X-ray diffraction. In particle size distribution analysis 10% of the material was below the size of 2 μm, while in inductive coupled plasma - atomic absorption spectrometry 58.56 wt% copper and 22.48 wt% of sulfur were found present in the final product along with the elements such as arsenic, lead, zinc, mercury, and manganese in traces.

Procedures for preparation of Lauha Bhasma are described in ancient texts of Ayurveda. These procedures also begin with different source material for iron such as Teekshna Lauha and Kanta Lauha etc. In the present study, we have selected different source materials viz. magnetite iron ore for Kanta Lauha and pure (Armco grade) iron turnings for Teekshna Lauha. The standard procedures of preparation of Lauha Bhasma are carried out in identical conditions for these two raw materials. The final product from the Puta are characterized by using X-ray diffraction and X-ray fluorescence spectroscopy to understanding the crystallographic form or forms of iron oxides and their composition at the end of each Puta. The iron content at the end of repeated Putas (18 for Kanta Lauha and 20 for Teekshna Lauha) have shown a decrease in case of Teekshna Lauha since the starting material is pure iron while it showed only marginal decreases in the case of Kanta Lauha because the Fe3O4 of magnetite is undergoing oxidation to Fe2O3. The trace elements remain within the Bhasma in the form of various oxides of Si, Al, Ca, etc.

Preparation of bhasma (calcined powder of metal/minerals) includes various processing steps like purification (Shodhana), levigation (Bhavana),calcinations cycle(Marana), improving quality and removing blemishes (Amritikarana) etc, processing of bhasma aims at formation of herbo-mineral complex molecule which can act in minimal dosage, palatable, easy for assimilation, highly efficacious with minimal or no complication. Although the most important equipment mentioned for Marana i.e. cow dung cakes and some type of woods are not only difficult to collect but also expensive and create pollution during puta and it's difficult task to give controlled heat in traditional method. Hence, a Modified Portable Bhasma Nirman Yantra (MPBNY) was prepared for puta (equipment for calcination) procedure which is easy to handle, portable and facilitate to supply controlled heat. A comparative study was conducted on Kasisa Bhasma prepared by traditional method and by using MPBNY with special reference to physico-chemical properties. The prepared Kasisa Bhasma was subjected to modern analytical parameters such as A.A.S. (Atomic Absorption Spectroscopy), X.R.D. (X-ray Diffraction) and Ayurvedic parameters eg. Rekhapurnatva (bhasma should enters in between lines of finger), Varitaratva (bhasma should float on the surface of water), Niramlatva (bitter less), Apunarbhava (bhasma should not regain its metallic nature after strong heating with jiggery, Abrus precatorius linn., honey and ghee) and Niruttha (bhasma should not regain its metallic nature after strong heating with silver). It was observed that Kasisa Bhasma of both methods possesses similar organoleptic as well as physico-chemical properties.

The Vanga Bhasma is an important one amongst the metallic Bhasmas. Mainly Gaja Puta, Ardhagaja Puta and Laghu Puta have been described for Marana of Vanga. The medicines, which are prepared from Gaja Puta, are said to be the best ones (Mahagunavidhayaka). Gaja Puta is commonly used in the preparation of almost all the Bhasmas. There are a few references found in classics regarding Ardhagaja Puta, but not any reference regarding its detail description, therefore, the effort was made to standardize both the Putas with regard to Vanga Bhasma. In the present study, Vanga Bhasma was prepared by Gaja Puta and Ardhagaja Puta. For Marana of Vanga, it was found that the Ardhagaja Puta is more convenient than Gaja Puta with respect to color and particle size analysis of Bhasma after Jarana procedure of Vanga.

Lauha Bhasma, an ayurvedic drug, is widely used in iron deficiency anaemia, this ancient drug is claimed to be better absorbed gastrointestinally, and is also claimed to be devoid of the usual side effects associated with administration of the allopathic iron preparations, Physical and chemical methods of standardization required for any quality preparation, is not found in the ayurvedic and the modern literatures for Lauha Bhasma. Thus an approach has been made to standardize Lauha Bhasma. For the purpose of analysis, samples of all the three commonly available variants of Lauha Bhasma were considered. Qualitative analysis indicates the presence of iron both in the ferric and the ferrous forms, A simple spectrophotometric method has been used for simultaneous determination of ferric ferrous and the total iron content in a single aliquot.
Swarna makshika (chalcopyrite) bhasma (SMB) has been used for different therapeutic purposes since long in Ayurveda. The present study is conducted to evaluate the effect of conventionally prepared SMB on different bio-chemical parameters in experimental animals, for providing scientific data base for its logical use in clinical practice. The genuine SMB was prepared by following classical techniques of shodhana and marana most commonly used by different Ayurvedic drug manufacturers. Shodhana was done by roasting raw swarna makshika with lemon juice for three days and marana was performed by 11 putas. The experimental animals (rats) were divided into two groups. SMB mixed with diluted honey was administered orally in therapeutic dose to Group SMB and diluted honey only was administered to vehicle control Group, for 30 days. The blood samples were collected twice, after 15 days and after 30 days of drug administration and different biochemical investigations were done. Biochemical parameters were chosen based on references from Ayurvedic classics and contemporary medicine. It was observed that Hb% was found significantly increased and LDL and VLDL were found significantly decreased in Group SMB when compared with vehicle control group. This experimental data will help the clinician for the logical use of SMB in different disease conditions with findings like low Hb% and high LDL, VLDL levels.

Swarna makshika [SM], a mineral having various therapeutic uses, has been used since long in Ayurveda. The present study was conducted to generate a fingerprint for raw and processed SM using techniques which can be used by pharmacies. Powdered SM was heated in an iron pan by adding lemon juice for 3 days, till liberation of sulfur fumes stopped. Bhasma of this shuddha SM was obtained by triturating it withit with shuddha gandhaka and lemon juice. It was then subjected to heat in 09* putas, and for firing in each puta, 4 kg cow dung cakes were used. To assure the quality of bhasma, rasa shastra quality control tests like nischandratva, varitara, amla pariksha, etc., were used. After the bhasma complied with these tests, the bhasma was analyzed using X-ray Diffraction (XRD) analysis of raw SM and SM bhasma revealed that raw SM contains CuFeS2, and SM bhasma contains Fe2O3, FeS2, CuS and SiO2. Scanning Electron Microscope (SEM) studies showed that the grains in SM bhasma were uniformly arranged in agglomerates of size 1-2 microns as compared to the raw SM which showed a scattered arrangement of grains of size 6-8 microns. It may be concluded that raw SM is a complex compound which gets converted into a mixture of simple compounds having very small particle size after the particular process of marana. This is the first report of fingerprinting of SM bhasma prepared using this particular method.

Tarakeshwara Rasa (TR) is an Ayurvedic herbomineral compound formulation used in the intervention of Prameha vis-à-vis diabetes mellitus. The present study was executed to establish a fingerprint for this unique formulation, which can be adopted by the Ayurvedic pharmacies for drug standardization. TR is a formulation prepared by the trituration of four ingredients Abhraka Bhasma (AB), Loha Bhasma (LB), Vanga Bhasma (VB) and Rasa Sindhura (RS) in equal quantities with honey for one day. Each of the ingredients were prepared according to the norms of Ayurvedic classical texts and by employing Electric Muffle Furnace as heating device for incineration. To ensure the proper preparation of Bhasmas, standard tests (Bhasma Pariksha) were employed. After Bhasma complies these tests, TR was prepared and subjected for qualitative analysis, X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) studies. LB, AB, VB, RS and TR were also studied for free metal presence by employing phosphomolybdic acid. Chemical analysis of TR reveals that it contains Fe, Sn, Hg, Al, Mn, Ca and Mg. XRD study indicates that TR contains Fe2O3 (maghamite) in major phase and SnO2 (cassiterite), HgS, SiO2, HgO in minor phases. SEM study revealed that the compound is an agglomeration of particles. The particle size was in between 0.5 and 2 μ. Free metal detection by phosphomolybdic acid revealed the absence of free metals in the final Bhasmas. This is the first study establishing the characterization of Tarakeshwara Rasa.

The use of metals in traditional medicines is very often seen as matter of concern these days, especially the Bhasma preparations which are always under stringent observations for containing highly reactive inorganic elements such as lead, mercury, arsenic and others. One of the Bhasma extensively used in routine Ayurvedic practice is Tamra (copper) bhasma. If it is not prepared properly or Shodhana procedure is not done properly, it acts as a poison. To indicate its toxic potential, Ashtamahadoshas (eight major ill effects) have been quoted in classics and due emphasis have been given to its Shodhana procedure. In the present study, Tamra bhasma prepared from Shodhita and Ashodhita Tamra was subjected to oral toxicity study to ascertain the role of Shodhana process on safety profile of Tamra bhasma on subchronic administration to albino rats. Both the samples were administered to rats for 45 consecutive days at the doses of 5.5, 27.5, and 55 mg/kg. Animals were sacrificed on 46th day and parameters like hematological, serum biochemical, and histopathology of various organs were studied. Results showed that Tamra bhasma prepared from Ashodhita Tamra has pathological implications on different hematological, serum biochemical and cytoarchitecture of different organs even at therapeutic dose level (5.5 mg/kg). Whereas, Tamra bhasma prepared from Shodhita Tamra is safe even at five-fold to therapeutic equivalent doses (27.5 mg/kg). These observations emphasize the role of Shodhana and importance of dose in expression of toxicity of the medicinal preparations.

Iron is one among the major metals present in the earth's crust and is essential for sound sustenance of human body. Its deficiency leads to various health ailments. Contemporary medicine advises iron supplements in iron deficiency anemia. Ayurvedic classics also quote significant information about administration of iron. Lauha Kalpas are the unique compound herbo-mineral formulations where iron (Lauha) is used as a major ingredient. Relevant literature (Bhaishajya Ratnavali, Charaka Samhita, Rasendra Sara Samgraha etc.) reviewed to gather information about Lauha Kalpas. Critical analysis of these Lauha Kalpas reveals that ancient seers administered iron in a better acceptable form. Unlike popular understanding these are not only Khalviya preparations; but Churna (powders), Avaleha (confectionaries), Rasakriya (solidified decoctions), and Putapaka (incinerated) form of preparations are also found. Apart from solid dosage forms, semisolid dosage forms mentioned in classics are very much useful. Unfortunately most of the formulations are not found in the market. Hence Pharmaceutical firms may bring these unique dosage forms in to the market to supply the healthcare needs of the community. It is interesting that iron preparations are used in Ayurveda in different medical conditions apart from anemia (Pandu). This leaves a scope for further researches on different dosage forms of iron and their indications.

Ayurveda is a unique system of medicine which uses metals and minerals in the form of bhasma (fine powder obtained through calcinations). Mandura is one of such mineral having various therapeutic uses. An effort has been made in the present study to characterize raw and processed Mandura using sophisticated analytical tools as a step forward to standardization. Mandura bhasma was prepared following references of Ayurvedic classics. To assure the quality of the prepared bhasma, Rasa Shastra quality control tests like rekhapurnatvam (particles enter into furrows of human hand), varitara (floating of product particles on water), irreversible etc., were used. Bhasma fulfilling these tests was analyzed using X-ray Diffraction (XRD) analysis. This revealed that raw Mandura contained Fe2Si04, and Mandura bhasma contained Fe2O3 and SiO2. Scanning Electron Microscopy (SEM) studies showed that the grains in Mandura bhasma were uniformly arranged in agglomerates of sizes 200-300 nm as compared to the raw Mandura, which showed a scattered arrangement of grains of sizes 10-2 microns. It may be concluded that this conversion of raw Mandura, a complex compound, into a mixture of simple compounds having nano-sized particles is due to the particular process of calcination employed.

Rasaka, which is one among the Maharasas, is an ore of zinc and has been used to extract Yashada in ancient times. It has a wide range of therapeutic applications, including in diseases like Prameha, Streeroga, and so on. The practice of Rasaka Bhasma preparation has declined with time due to various reasons. The present study aims to identify the genuine samples of Rasaka, prepare Rasaka Bhasma by subjecting it to Shodhana and Marana, and undertake a physiochemical analysis of the prepared Bhasma with an eye toward the standardization of Rasaka Bhasma.

Metallic Bhasmas are highly valued and have their own importance in Ayurvedic formulations. To testify the Bhasmas various parameters have been told in Rasashastra classics. Tamra Bhasma (TB) with its different properties is used in the treatment of various diseases is quiet famous among the Ayurvedic physicians (Vaidyas).
The present study was carried out to set up the quality control parameters for the TB by making the use of classical tests along with advanced analytical tools.
Settings and Design:
Copper wire taken for the preparation of Bhasma was first analyzed for its copper content and then subjected to Shodhana, Marana and Amrutikarana procedures as per the classical references. Final product complied with all the classical parameters like Rekhapurnatwa, Varitaratwa etc.
Materials and Methods:
After complying with these tests TB was analyzed by advanced analytical techniques like particle size distribution (PSD) analysis, scanning electron microscopy (SEM), and inductive coupled plasma spectrometry (ICP).
PSD analysis of TB showed volumetric mean diameter of 28.70 μm, 50% of the material was below 18.40 μm size. Particle size less than 2μm were seen in SEM. 56.24 wt % of copper and 23.06 wt % of sulphur was found in ICP-AES. Heavy metals like cadmium, selenium were not detected while others like arsenic, lead and mercury were present in traces.
These observations could be specified as the quality control parameters conforming to all the classical tests under the Bhasma Pariksha.

In the practice of Ayurveda, where herbomineral formulations are said to be made biocompatible through specific processes like Shodhana and Marana, the western medical science on the contrary has raised the safety concerns of these formulations in the recent past. In the present study, comparative physico-chemical analysis of Naga bhasma, a herbo-mineral preparation having a reputation of miraculous drug commonly used to treat several health disorders, was carried out using five marketed formulations through analytical methods like differential scanning calorimetry, X-ray difraction, thermogravimetric analysis, Fourier Transform infrared spectroscopy and also subjected for particle size analysis and estimation of trace and heavy metals to access the safety of these formulation. The results revealed variable observations regarding particle size, metal form and content of lead. The presence of free lead in five different formulations indicated towards the possible risk of severe side effects to the consumer. Present findings certainly put doubt over the safety of this formulation but at the same time, variation in the results with all five formulations also indicated that these formulations were not prepared as per the mentioned Ayurvedic text. Hence, enforcement of strict regulatory guidelines is strongly warranted before launching into the market. Further, a series of biological studies need to be conducted before taking any final verdict on the safety of this formulation.

Now-a-days it has become quite common to use modern electric heating devices in the place of conventional ones. A stud was conducted to standardize the temperature for the preparation of Pravala Bhasma by using Electric Muffle furnace (EMF) The details are presented in this article.
Metals have had a long history in Ayurvedic system of medicine. Mercury (Parada), gold (Swarna), silver (Rajata), copper (Tamra), iron (Lauha), tin (Vanga), lead (Naga), and zinc (Yasada) are used in therapeutics in an incinerated (Bhasma) form. The pharmacological actions, therapeutic indications, adverse effects and management of adverse effects of these metals are described and emphasis has been given to the proper preparation, rational dose and duration during clinical practice in the classics of Ayurveda. Most important observation is, there are no contraindications of these Bhasmas, indicating universal applicability to all age levels with suitable adjuvant, proper dose and duration.

Rasa Shastra is a branch of Ayurveda which deals with the processing of minerals and metals having therapeutic importance. Rajata comes under the group of metals having high therapeutic value. Minerals and metals are mostly used in the form of Bhasma. During the medieval period Rasacharyas extensively worked and developed a number of processing methods for a single drug. They all are standard manufacturing procedures (SMP) which ensure the quality, safety, efficacy and reproducibility of the product. Earlier Ayurvedic physicians were producing medicines by themselves according to their need. Now a day, due to commercialization of Ayurvedic medicines and ignorance of classical methods, quality of drugs has deteriorated. Presently, the demand of Ayurvedic drugs in the global market is increasing day by day. Hence it is the need of time to develop SMP for Ayurvedic products for global acceptability. This paper aims at providing SMP for the manufacture of Rajata Bhasma and also attempts to study the effect of Shodhana process on Rajata. Rajata was obtained from the local market of Varanasi. Rajata Bhasma was prepared and it was observed that during the preparation of Rajata Bhasma, use of Muffle Furnace instead of conventional Puta is more advantageous due to better temperature control. Use of mercury and sulphur together acts as best medium in the preparation of Rajata Bhasma.

The metal, Tamra though mentioned in Ayurveda with a wide range of therapeutic utilities; is attributed with Ashta Maha Dosha. Hence, one should be cautious while using Tamra Bhasma. Considering the significance of Tamra in therapeutics, many studies have been carried out at different centers of India. Aim of the present study was to compile such available research works done on Tamra in the Department of Rasa Shastra and Bhaishajya Kalpana (RS and BK), IPGT and RA, Jamnagar and provide brief information about pharmaceutical, analytical, and pharmacological studies. Total eleven studies on Tamra Bhasma, which revalidated the impact of classical guidelines, safety issues, and therapeutic utilities, were screened from PG Department of RS and BK, Institute for Post-Graduate Teaching and Research in Ayurveda, Gujarat Ayurved University, Jamnagar. All studies revealed that Tamra Bhasma is safe clinically, experimentally at Therapeutic Equivalent Dose (TED) levels as no toxic hazards were reported during the treatment period. In all aspects (pharmaceutical, pharmacological, and clinical) Somnathi Tamra Bhasma has proven to be better than Tamra Bhasma. The clinical efficacy of Tamra Bhasma has been evaluated in Shvasa, Kasa, Yakrit Pliha Vriddhi, Grahani, etc. conditions. Satisfactory responses with a decrease in the intensity of signs and symptoms were reported in all the studies. Though certain limitations were observed in these researches, the results can be considered as a lead for further well stratified studies covering larger population. No adverse effects were reported in any of these studies.

Traditional medicines have maintained their popularity in all regions of the developing world and are being adopted increasingly by people worldwide. Indian traditional system of medicine Ayurveda make use of unique metallic-herbal preparations (called Bhasma) which involves different processing steps including repeated steps of calcination of metal in the presence of natural precursor (herbal juices, decoctions, and powders, etc). It has been recently established that Bhasma contains nano/sub-micron size particles and different nutrient elements. However, the role and the end product of the raw materials, especially the herbal parts, used during the synthesis of the drug (Bhasma) is one of the important but unanswered problems in such medicinal preparations. Present work on Naga Bhasma is an attempt to understand the role of natural precursors in detail. Our results on infrared, Raman and X-ray photoelectron spectroscopy along with thermal measurements identify the presence of carbonaceous material (hydrogenated amorphous carbon) in the drug along with other compounds. In addition, this work also suggests the science and mechanism behind such complex preparations which could help in standardization of such medicines.

Samples of marketed Lauha bhasma from different manufactures were evaluated chemically. Apart from the 81 -85% iron content, the 15-19% other constituents were determined therein. Ferrous ferric and total iron in a single aliquot were determined spectrophotometrically, Qualitative and chromatographic analysis indicate the presence of sodium, potassium, calcium copper and cobalt in the samples, silicious matter and traces of ascorbic acid were present while tannin was absent in Lauha bhasma . Quantitatively sodium and potassium were determined by flame spectrometry. Upon fractionation, water soluble and acid soluble contents were determined.
After analyzing the Lauha Bhasma samples qualitatively and quantitatively, in-vivo studies on healthy adult male rabbits were carried out. Randomly selected anaemic rabbits were divided into different groups and three variants of Lauha Bhasma and ferrous sulphate sample were administered to each group. The effect of each formulation was monitored by measuring the haemoglobin (Hb) content spectrophotometrically (cyanomethaemoglobin method). Increase in the haemoglobin content was found to be significant in case of the ayurvedic formulations as compared to the ferrous sulphate sample.
The one of the oldest system of medicine, Ayurveda is momentous in audience of worldwide on virtue of its holistic approach of life. Formulations of Ayurveda consist of substances of herbal, mineral/metal and animal origin which are processed pharmaceutical to have therapeutic effects. This is attribute of processes of Shodhan (purification/potentiation), Bhavana (impregation /levigation) and Marana (incineration/calcinations) of Rasa Shastra which acclimatize these toxic industrial matter to a effective remedies known as herbo mineral formulations (Rasaoushadhies) of Ayurveda. In recent past there is prevalence of some doubt on safety and efficacy of these medicines. In this review paper we tried to justify application of these medicines as these are time tested and showed wonderful clinical adaptability. We also attempted to establish new facts of figures of core science in explanation of these medicines.
