Mukta Shukti (Pearl oyster shell); a sudha varga dravya, attains better therapeutic properties with proper sodhana and marana processes. It is indicated in Amlapitta, Parinamashoola and Annadravashoola. Acharya Susruta mentioned; Amla is the property of Vidagdha Pitta. The term Amlapitta may be correlated with Acid reflux syndrome which comprises of various types of Gastro esophageal reflux diseases like Gastritis, Peptic ulcer etc. A peptic ulcer is a sore on the lining of the stomach or duodenum, the beginning of the small intestine. A bacterium called Helicobacter pylori is a major cause of peptic ulcers. An attempt was made in this regard to establish standards to assure quality and to assess antiulcer activity of Mukta Sukti Bhasma.
Mukta sukti Bhasma prepared as per Rasatarangini and subjected to Atomic absorption spectroscopy (AAS) and X ray diffraction (XRD). Anti ulcer activity of Mukta sukti Bhasma in Albino rats by Aspirin induced gastric ulcer. Sucralfate as standard group and normal food water as control group used for the comparison.
Mukta sukti Bhasma showed highly significant Anti ulcer activity than control group. The alkaline pH and chemical components might have contributed by inhibiting secretions, neutralizing the acidity and reducing size of the ulcerative lesions. Presence of Calcium (Ca), Magnesium (Mg), Manganese (Mn), Iron (Fe), Potassium (K), Aluminum (Al), Copper (Cu), Sodium (Na) and Zinc (Zn) were detected in raw Mukta sukti and Mukta sukti Bhasma. X ray diffraction shown face centered Cubic, hexagonal, tetragonal and monoclinic crystal structures.
In aspirin induced model, the Mukta sukti Bhasma and standard group (Sucralfate) showed highly significant Anti ulcer activity than control group (food water). The Mukta sukti Bhasma showed highly significant Anti ulcer activity than standard group (Sucralfate) when compared. This experimental study has given scientific evidence for the claim in the ancient text regarding the Anti ulcer property of Mukta sukti Bhasma which gives scope for conducting clinical study.
In the present research paper, the work done on pharmaceutical study of Lauha Bhasma conducted in the Department of Rasa Shastra under the postgraduate research programme is being presented. The pharmaceutical processing of Lauha Bhasma was performed by following samanya shodhana, vishesha shodhana and marana of Lauha. Under the process of marana, three specific pharmaceutical techniques were followed, viz. bhanupaka, sthalipaka and putapaka. During the putapaka process, an electric muffle furnace (EMF) was used. The temperature of puta was studied in two batches, viz. in Batch I, a temperature of 800°C was maintained whereas in Batch II, a temperature of 600°C was maintained. The purpose behind selecting two temperatures was to validate the process of marana of Lauha and to determine an ideal temperature for the preparation of Lauha Bhasma in EMF. It is found that after 20 puta at a temperature of 600°C, the Lauha Bhasma was prepared properly. The entire characteristic of Lauha Bhasma, like “pakwa jambu phala varna,” varitar, etc. was attained at 600°. At a temperature of 800°C, the process could not be carried out smoothly. The pellets turned very hard and brassy yellow in color. The desired color was attained only after decreasing the temperature in further puta.

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.

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.

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.

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.

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.

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.

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.

Swarna bhasma (gold bhasma) preparations are widely utilized as therapeutic agents. However, in vitro biological evaluations of bhasma preparations are needed along with the physicochemical characterization for present day standardization of metallic bhasma preparations to meet the criteria that supports its use. Therefore, an attempt has been made to evaluate the protein adsorption, blood compatibility and complement activation potential of two batches of Swarna bhasma preparation, along with its physicochemical characterization. The particle size, morphology, elemental analysis, and in vitro cytotoxicity were evaluated initially. Red blood cell hemolysis, aggregation studies with blood cells, protein adsorption, complement C3 adsorption, platelet activation and tight junction permeability in Caco-2 cell line were investigated. The Swarna bhasma preparations with a crystallite size of 28–35 nm did not induce any blood cell aggregation or protein adsorption. Activation potential of these preparations towards complement system or platelets was negligible. These particles were also non-cytotoxic. Swarna bhasma particles opened the tight junctions in Caco-2 cell experiments. The results suggest the application of Swarna bhasma preparations as a therapeutic agent in clinical medicine from the biological safety point of view.

Ayurveda and other Indian system of medicine use metals, but their use is also amply described in Chinese and Egyptian civilization in 2500 B.C. Bhasma are unique ayurvedic metallic/minerals preparation, treated with herbal juice or decoction and exposed for Ayurveda, which are known in Indian subcontinent since 7th century A.D. and widely recommended for treatment of a variety of chronic ailments. Animal's derivative such as horns, shells, feathers, metallic, nonmetallic and herbals are normally administered as Bhasma. A Bhasma means an ash obtained through incineration; the starter material undergoes an elaborate process of purification and this process is followed by the reaction phase, which involves incorporation of some other minerals and/or herbal extract. There are various importance of Bhasma like maintaining optimum alkalinity for optimum health, neutralizing harmful acids that lead to illness; because Bhasma do not get metabolized so they don’t produce any harmful metabolite, rather it breakdowns heavy metals in the body. Methods including for Bhasma preparation are parpati, rasayoga, sindora, etc., Bhasma which contain Fe, Cu, S or other manufacturing process plays a specific role in the final product(s). Particle size (1-2 μ) reduced significantly, which may facilitate absorption and assimilation of the drug into the body system. Standardization of Bhasma is utmost necessary to confirm its identity and to determine its quality, purity safety, effectiveness and acceptability of the product. But the most important challenges faced by these formulations are the lack of complete standardization by physiochemical parameters.

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.

Bhasma means ash but according to Ayurveda, Bhasma means conversion of a metal into a form which is irreversible in the sense that one cannot derive the metal back from it again (Apunarbhava). It should be so light so that it must float on the surface of water after sprinkling, called Varitara. Its particle should be so small that it can enter in to the creases of fingers called Rekha-purnatva. The preparative procedure of Bhasma is a bit complicated. Many texts are available regarding the identification, acceptable qualities of metals and minerals, their purification, uses and method of preparation of their Bhasma. But in many texts, the method of Bhasma preparation of some metals and minerals is mentioned very briefly, i.e. their references are available in Sutrarupa. This leads to many practical difficulties in the preparation of Bhasma. Kasisa Bhasma is one of them. The present work was aimed to study the basic concept of Bhasma Kalpana by means preparing Kasisa Bhasma. This study suggests some modifications and ways for standardization of Bhasma procedure.

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.

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.

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.

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.

Arsenic and lead have been found in a number of traditional Ayurvedic medicines, and the practice of Rasa Shastra (combining herbs with metals, minerals and gems), or plant ingredients that contain these elements, may be possible sources. To obtain an estimate of arsenic and lead solubility in the human gastrointestinal tract, bioaccessibility of the two elements was measured in 42 medicines, using a physiologically-based extraction test. The test consisted of a gastric phase at pH 1.8 containing organic acids, pepsin and salt, followed by an intestinal phase, at pH 7 and containing bile and pancreatin. Arsenic speciation was measured in a subset of samples that had sufficiently high arsenic concentrations for the X-ray absorption near edge structure analysis used. Bioaccessible lead was found in 76% of samples, with a large range of bioaccessibility results, but only 29% of samples had bioaccessible arsenic. Lead bioaccessibility was high (close to 100%) in a medicine (Mahayograj Guggulu) that had been compounded with bhasmas (calcined minerals), including naga (lead) bhasma. For the samples in which arsenic speciation was measured, bioaccessible arsenic was correlated with the sum of As(V)–O and As(III)–O and negatively correlated with As–S. These results suggest that the bioaccessible species in the samples had been oxidized from assumed As–S raw medicinal ingredients (realgar, As4S4, added to naga (lead) bhasma and As(III)–S species in plants). Consumption at recommended doses of all medicines with bioaccessibile lead or arsenic would lead to the exceedance of at least one standard for acceptable daily intake of toxic elements.

Gastritis leadind to G.I.ulcers is a very prevalent metabolic and life style disorder. Many a times it is condition which arise due to various medications like NSAID's. Drugs effective in Ulcer protection is the need of the hour. Medications such as sucralfate in conventional system do work but in higher dose and with limitations. Thus, present study has been carried out, to evaluate efficacy of Varatika bhasma in ulcer protective activity with standard control as Sucralfate in aspirin induced ulcer.
Varatika bhasma was prepared by shodhana with kanji, bhaavana with kumari swarasa and subjecting to gajaputa. Further it was analyzed and used for experimental study. Winstar strain albino rats of either sex was taken in 3 groups with 6 rats in each group. Control group with food and water, standard with sucralfate and test with varatika bhasma was given for 6 days. on 7th day ulcer was induced with aspirin. later rats were sacrificed to cut open the stomach and to study the ulcer index and histopathology.
When compared to Sucralfate for ulcer protective effect, Varatika Bhasma shows significant result in lower doses. (Sucralfate 1 gm 6 hourly and Varatika Bhasma 250 mg twice daily). In ulcer index and histopathology studies, there were less / no ulcers found in the group treated with Varatika Bhasma in comparison with Sucralfate and Control group.
For the ulcer protection, Varatika Bhasma provides better and promising result when compared to Sucralfate. This also cuts the cost of medication and time constrain for the administration of the medicine.
Mayur Puccha bhasma (Calx of peacock feather), an Ayurvedic animal product prepared from peacock feather with different methods mentioned in Siddhayogasangraha, Bhaishajya Samhita. It is mainly indicated in Chardhi, Hikka, and Swasa. Till today no research work has been done on Mayur Puccha bhasma prepared by two different methods and exact pharmacopeial standards are also not available. The present study was aimed to assess the Physico chemical components of Mayur Puccha bhasma prepared by Ghee flame and Gajaputa method & to lay down the Pharmacopeial standards for the assessment of its standard qualities.
Mayur Puccha bhasma was prepared by two classical procedures, one by burning on ghee flame (Sample A) second by giving four Gajaputas (Sample B) and finished products were subjected to various Physico chemical studies to find out Ash value, PH value, Sp gravity, Moisture content, Preliminary organic analysis and Gravimetric analysis.
Both the bhasmas exhibited marked difference in colour, moisture content and % of inorganic compounds. The bhasma prepared by Gajaputa method contains essential and beneficial inorganic elements, electrolytes in more quantity with less moisture content, neutral pH.
Sample B is having less moisture (1%) content which may contribute for increasing its stability and having high ash value as it consists of inorganic elements in more quantity and indicates that bhasma prepared properly. The neutral pH of Sample A and B indicates no significance difference in their pH value. Sample B contains Copper, Iron, Zinc, Sodium, Potassium, Calcium, Magnesium, Manganese, Aluminium, in more quantity than Sample A but in a permissible amount. As Mayur Puccha bhasma prepared by Gajaputa method contains essential and beneficial elements, having natural pH and free from steroids may contribute as one of the usefully and safe alternative medicine in Chardhi, Hikka, Swasa.
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.

Efforts have been made to lay down analytical standards for Mehamudgara vati (MMV), which were not found reported till date. Weight variation showed that 90% tablets of MV manufactured in the Gujarat Ayurved University Pharmacy were within acceptable range (323 mg ± 10%), pH 4.58, and disintegration time 17 min, whereas hardness was 1.25 kg/cm2. Loss on drying was found to be 9.3% w/w, acid insoluble ash was 0.9 %w/w, water soluble extract was 24.06% w/w and methanol soluble extract 14.1% w/w. Determination of iron as Fe2O3 was done as Lauha bhasma being the major ingredient of MMV. The result showed that iron content was reduced in the formulation (28.67%) as compared to that in Lauha bhasma (61.19%). In TLC, 5 spots each at 254 nm and 366 nm were found.

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.

Ayurvedic formulations usually contain ingredients of herbal, mineral, metal or animal in origin. Nāga bhasma (lead calx) is a potent metallic formulation mainly indicated in the treatment of Prameha (~diabetes). Until date, no published information is available in compiled form on the formulations containing Nāga bhasma as an ingredient, their dose and indications. Therefore, in the present study, an attempt has been made to compile various formulations of Nāga bhasma indicated in treating Prameha.
The present work aims to collect information on various formulations of Nāga bhasma mainly indicated in treating Prameha and to elaborate the safety and efficacy of Nāga bhasma as a Pramehaghna (antidiabetic) drug.
Materials and Methods
Critical review of formulations of Nāga bhasma is compiled from various Ayurvedic texts and the therapeutic efficacy of Nāga bhasma is discussed on the basis of available data.
Result and Conclusion:
Antidiabetic formulations of Nāga bhasma were discovered around 12th century CE. There are 44 formulations of Nāga bhasma mainly indicated for Prameha. Haridrā (Curcuma longa Linn), Āmalakī (Emblica officinalis), Guḍūci (Tinospora cordifolia) and Madhu (honey) enhance the antidiabetic action of Nāga bhasma and also help to prevent diabetic complications as well as any untoward effects of Nāga bhasma. On the basis of the reviewed research, it is concluded that Nāga bhasma possesses significant antidiabetic property.

Mayūrapuccha Bhasma (Calx of peacock feather) is an Ayurvedic animal product prepared from peacock feathers by employing two different methods as mentioned in Siddhayogasaṅgraha and Bhaiṣajya saṁhitā. It is mainly indicated in vomiting, hiccough, and respiratory disorder.
Materials and Methods:
In the present study, Mayūrapuccha Bhasma was prepared by two classical procedures, one by burning on ghee flame and the other by giving Gajapuṭa (burning the peacock feathers at about 1000°C by using a thousand cow dung cakes). The products so obtained were subjected to various physico-chemical studies to find out ash value, pH value, specific gravity, moisture content, preliminary organic analysis, gravimetric analysis, chemical components, and to lay-down the pharmacopeial standards for standardization of Mayūrapuccha Bhasma.
Results and Conclusion:
Both the Bhasmas exhibited marked difference in color, moisture content, and percentage of inorganic compounds. The Bhasma prepared by Gajapuṭa method contains essential and beneficial inorganic elements, electrolytes in larger quantity, and lower moisture content.
