1.  Clinical efficacy of Mehamudgara vati in type 2 diabetes mellitus 
Ayu  2011;32(1):30-39.
In type 2 diabetes, insulin resistance is the main problem that is associated with a cluster of conditions such as obesity and hyperlipidemia. The present study was designed with the objective to evaluate the role of Mehamudgara vati (MMV), which was expected to work at the level of Medodhatwagni due to its Medohara properties, to have an effective control on type 2 diabetes. To fulfill the objective, known patients of type 2 diabetes attending the OPD and IPD of Kayachikitsa Department, IPGT and RA, were selected and were divided in two groups. In Group A, MMV was given 3 tab. thrice a day with lukewarm water for 3 months and in Group B, the patients who were already taking modern antidiabetic treatment, although their blood sugar level was not well under control, were additionally given MMV in the same manner. The formulation has shown a highly significant decrease in the fasting and post-prandial blood sugar level. The formulation has also shown a synergistic action when combined with the modern antidiabetic drugs due to its known hypolipidemic, hypocholesterolemic, hepatoprotective, antihyperglycemic, antistress, antioxidant and immunomodulatory activities.

2.  STANDARDIZATION AND BIOAVAILABILILTY OF AYURVEDIC DRUG LAUHA BHASMA PART-1 PHYSICAL AND CHEMICAL EVALUATION 
Ancient Science of Life  1995;15(2):129-136.
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.

3.  Standardization of a Traditional Polyherbo-Mineral Formulation-Brahmi Vati 
The present study deals with standardization of an in-house standard preparation and three marketed samples of Brahmi vati, which is a traditional medicine known to be effective in mental disorders, convulsions, weak memory, high fever and hysteria. Preparation and standardization have been done by following modern scientific quality control procedures for raw material and the finished products. The scanning electron microscopic (SEM) analysis showed the reduction of metals and minerals (particle size range 2–5 µm) which indicates the proper preparation of bhasmas, the important ingredient of Brahmi vati. Findings of EDX analysis of all samples of Brahmi vati suggested the absence of Gold, an important constituent of Brahmi vati in two marketed samples. All the samples of Brahmi vati were subjected to quantitative estimation of Bacoside A (marker compound) by HPTLC technique. Extraction of the samples was done in methanol and the chromatograms were developed in Butanol: Glacial acetic acid: water (4.5:0.5:5 v/v) and detected at 225nm. The regression analysis of calibration plots of Bacoside A exhibited linear relationship in the concentration range of 50–300 ng, while the % recovery was found to be 96.06% w/w, thus proving the accuracy and precision of the analysis. The Bacoside A content in the in-house preparation was found to be higher than that of the commercial samples. The proposed HPTLC method was found to be rapid, simple and accurate for quantitative estimation of Bacoside A in different formulations. The results of this study could be used as a model data in the standardization of Brahmi vati.

4.  Critical review on the pharmaceutical vistas of Lauha Kalpas (Iron formulations) 
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.

5.  Identifications studies of Lauha Bhasma by X-ray diffraction and X-ray fluorescence 
Ayu  2012;33(1):143-145.
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.

6.  PA01.41. Pharmaceutico-analytical study of mayur puccha bhasma prepared by two methods 
Ancient Science of Life  2012;32(Suppl 1):S91.
Purpose:
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.
Method:
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.
Result:
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.
Conclusion:
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.

7.  Scientific evaluation of some Ayurvedic preparations for correction of iron deficiency and anemia 
A number of preparations are available in Ayurved for treatment of anemia and iron deficiency. This study was designed to evaluate efficacy of some of them. Six most commonly used Ayurvedic iron containing preparations (Navayasa Curna, Punarnavadi Mandura, Dhatri Lauha, Pradarantaka Lauha, Sarva-Juara-Hara Lauha and Vrihat Yakrdari Lauha) were given in a dose of 250 mg b.d. for 30 days to six groups of iron deficient anemic patients; each group consisting of 20 patients. A control group was given Allopathic preparation—Irex-12, (containing—ferrous fumarate, vitamin C, folic acid and vitamin B12); 1 capsule daily for 30 days for comparison. All hematological and iron parameters were determined before and after completion of treatment. The results showed that there was statistically significant rise (p<0.001) in all of them—Hb, PCV, TRBC, MCV, MCH, MCHC and plasma iron, percent saturation and plasma ferritin. Total iron binding capacity decreased significantly (p<0.001). The response of most of Ayurvedic preparations was better than Allopathic preparation and there was no side effect as observed with iron salts The Hb regeneration rate was 0.10 g/dl/day for Allopathic preparation; while it was above this value for all Ayurvedic preparations exceptPradarantaka Lauha which was least effective.Sarva-Juara-Hara Lauha was the drug of choice as Hb regeneration with it was highest 0.16 g/dl/day. Upon analysis of Ayurvedic drugs, these results were found to be consistent and correlated with iron content of the preparation.

8.  Pharmaceutical study of Lauha Bhasma 
Ayu  2010;31(3):387-390.
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.

Ancient Science of Life  2012;32(Suppl 1):S69.
Purpose:
The desire to have a healthy progeny is innate & very intense in every living being. The hectic life and tremendous stress in today's world has made the conception & continuation of pregnancy to term very difficult. Anaemia is one of the common disease conditions which affect a pregnant woman. In Ayurvedic classics anaemia in pregnancy is taken under the Rasa Pradoshaja Vikara. It is also a Santharpanotha Vikara.
Method:
Total 26 patients were registered from O.P.D. And I.P.D. of the department of Streeroga & Prasootitantra, out of them 4 patients were discontinued. They were randomly divided in to two groups; Group A (n 12) Pandughni Vati 2 tablets of 250mg tds and Group B (n 10) Dhatri Lauha Vati 1 tablet of 250mg tds. Dhatri Lauha Vati was selected for the present study due to its Pandughna, Prinana, Raktaprasadana properties. AYUSH department has developed a compound formulation Pandughni Vati. As a part of its clinical trials the same drug was selected for present study.
Result:
Group A The result observed in Shwasa (dyspnoea) (60%) and Hridrava (palpitation) (53.33%) were highly significant statistically (<0.001). Daurbalya (33.33%), Shrama (fatigue) (40%), Aruchi (anorexia) (28.57%) and Pindikodvestana (55.55%) were decreased significant statistically (<0.05) whereas in Panduta (pallor) (24%) it was not significant. In Group B, results observed were highly significant statistically (<0.001) in Panduta (pallor) (50%) and Shwasa (dyspnoea) (56.25%). The results in Shrama (fatigue) (61.54%), Hridrava (palpitation) (55.55%), Aruchi (anorexia) (42.85%), Pindikodvestan, (49.49%) were significant
Conclusion:
On comparing the effect of therapy study was finding better percentage improvement in-group B consistently in most of subjective and objective parameters. So it can be said that Dhatri Lauha Vati has somewhatbetter results, proving it better to Pandughni Vati.

13.  Comparative study on Kasisa Bhasma prepared by two different methods 
Ancient Science of Life  2011;31(2):62-72.
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.

14.  Development of a chewable tablet from Dugdhāmalakyādi Yoga: An Ayurvedic preparation 
Ancient Science of Life  2012;32(1):34-37.
Background:
Āmalaki (Embelica officinalis Gaertn.) is one of the most celebrated herbs in the Indian system of traditional medicine. It is one of the best Rasāyana-s (health promoting) drug. In Dugdhāmalakyādi yoga, Āmalaki (Embelica officinalis Gaertn.) powder is administered along with milk in case of svarabhaṅga (hoarseness of voice). Here an attempt is made to convert this formulation into chewable tablet without altering its property to improve its palatability, shelf life and fixation of proper therapeutic dose.
Methodology:
Chewable tablets were prepared by wet granulation method. Here, Āmalaki powder was prepared initially and it was mixed with additives and preservatives. Granules were prepared from this mixture by adding binding agent, finally compressed in to tablets.
Results and Conclusion:
The physico-chemical analysis of Āmalaki standard are: Foreign Matter-Nil, Acid insoluble Ash-0.51%w/w, Water soluble Ash-2.01% w/w, Alcoholic Extractives-44.48%, Aqueous Extractives 67.52%, pH-3.1, Moisture content-8.19%. Quality control test for chewable tablet was carried out and found satisfactory with general characteristics of tablet viz. hardness 1.8, disintegration time 15-20 min, friability 0.5%, weight variation +/- 3%. The TLC of Āmalaki powder showed 3 spots with Rf value 0.14, 0.4, and 0.73 and the chewable tablets showed 2 spots with Rf value 0.31 and 0.89 under 254 nm. The adaptation of modern techniques or methods to convert the Ayurvedic formulations without altering its therapeutic property is necessary to made them suitable for the present trends of newer drug delivery dosage forms.

16.  PA02.12. Toxicity studies on shankha vati 
Ancient Science of Life  2013;32(Suppl 2):S57.
Purpose:
Shankha Vati, a classical Ayurvedic formulation that is widely used by the practitioners of Ayurveda, contains a heavy metal i.e. Parada (mercury) and a poisonous herbal drug i.e. Vatsanabha (Aconitum chasmantum Staff.ex.Holmes) along with other ingredients. There are certain apprehensions on this formulation, mainly due to the presence of its ingredient Vatsanabha. Shankha Vati (Bhaishajya Ratnavali 10/186 – 187, also in Ayurvedic Formulary of India Part1), is one of the formulations in which Vatsanabha is used without its usual coingredient and antidote Tankana (borax). With an hypothesis that classical combination of Shankha Vati is not completely safe and there could be some adverse effects due to the presence of poisonous ingredient Vatsanabha in it, and any possible adverse effects of Shankha Vati due to the presence of Vatsanabha will be nullified by the addition of Tankana to the formulation, another modified formulation with the addition of purified Tankana equal to the quantity of Vatsanabha in the classical Shankha Vati, was also taken up for the study.
Method:
Acute toxicity study as per OECD Guideline 425, and Chronic toxicity study (90 days with the recovery period of 30 days) as per AYUSH170 guideline (Guidelines for preclinical safety evaluation for Ayurveda, Siddha and Unani drugs and other traditional medicines in India) were carried out. Biochemical and haematological investigations were carried out on 30th, 60th, 90th and 120th days. Histopathological study of acute chronic toxicity study were carried out.
Result:
Histopathological study of both acute and chronic toxicity study were also carried out. There were no toxicity related changes found in the animals treated classical Shankha Vati as well as modified Shankha Vati in both acute and chronic toxicity study. Similarly biochemical and haematological investigations also did not toxicity related changes.
Conclusion:
Classical formulation of Shankha Vati is completely safe and there is no need to modify the composition to make it safer.

17.  Bioaccessibility of lead and arsenic in traditional Indian medicines 
The Science of the total environment  2011;409(21):4545-4552.
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.

18.  SAFETY AND TOXICITY PROFILE OF SOME METALLIC PREPARATIONS OF AYURVEDA 
Ancient Science of Life  2006;25(3-4):57-63.
Metals and minerals are used profusely in practice of Ayurveda after proper incineration by the name of Bhasma. Some metals and minerals have the potency to produce toxic effects in human being. In this paper safety and toxicity profiles of Tamra Bhasma (incinerated copper, Cu), Lauha Bhasma (incinerated iron, Fe), and Yashada Bhasma (incinerated Zinc, Zn) has been presented, which reveal no serious deleterious effects on body function as a whole.

19.  STANDARDIZATION AND BIOAVAILABILITY OF AYURVEDIC DRUG LAUHA BHASMA- PART –II COMPARATIVE BIOAVAILABILITY STUDIES 
Ancient Science of Life  1995;15(2):140-144.
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.

20.  Review of research works done on Tamra Bhasma [Incinerated Copper] at Institute for Post-Graduate Teaching and Research in Ayurveda, Jamnagar 
Ayu  2013;34(1):21-25.
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.

21.  PA01.27. Standardization of ayurvedic formulation ‘eladi vati’ 
Ancient Science of Life  2012;32(Suppl 1):S77.
Purpose:
Contamination, deterioration and variation in composition problem of herbal medicines can be resolved by developing physico chemical fingerprints for the standardization of the drugs and comparing them with the reference authentic drugs, variation between preparations from different companies and by evaluating batch-to-batch changes during long term storage.
Method:
In present context we had standardized the ayurvedic preparation Eladi vati by using chemical markers. This vati and individual herbs had been evaluated for various physicochemical parameters, in process evaluation parameters, TLC (as identification of active principles), quantitative determination of marker compounds by HPLC method, determination of microbial contamination and toxic heavy metals by Atomic Absorption Spectrophotometer. The piperine, gallic acid and glycyrrhizic acid were quantitatively determined. Gynaecology were consulted for relevant information.
Result:
The results obtained with individual herbs had been compared with standards and results obtained with formulation had been compared with the other similar vati formulations available in the market. The results are almost alike in the Piperine, Glycyrrhizic acid and Gallic acid content. The concentration of heavy metals and microbial contamination were found under limit in ppm and colony forming units per gm respectively.
Conclusion:
The method can be suggested for effective quality control of herbal products and will establish standardization parameters for identification, quantification and purity determinations.

22.  Efficacy of Trikatrayadi Lauha in Panduroga with reference to Iron Deficiency Anemia 
Ayu  2012;33(1):62-67.
The common nutritional deficiency, iron deficiency, causes Iron Deficiency Anemia (IDA) throughout the world especially in the developing countries. In Ayurveda, different herbal, mineral or herbomineral drugs have been emphasized to combat anemia (Panduroga). Trikatrayadi Lauha and Fersolate-CM (a modern medicine taken as standard control) were administered to the patients to evaluate their role in Panduroga. A simple random sampling method was followed for the clinical study. The 56 iron deficiency anemic patients of both sexes and age group between 16 to 70 years divided into two groups – Group-A (n=34) and Group-C (n=22) were treated with Trikatrayadi lauha and Fersolate-CM, respectively. Both drugs provided significant effect on the signs and symptoms of Shrama (fatigue), Shwasa (dyspnea on exertion), Daurbalya (weakness), Pandu Varna (pallor/yellowish-whitish), Hridspandana (palpitation), Hatanala (diminished digestive capacity), Bhrama (giddiness), Aruchi (anorexia), Arohana Ayasa (exhaustion during climbing), Shiroruja (headache) and Shotha (edema). Trikatrayadi Lauha provided significant results on Hb gm%, RBC, PCV, MCV, serum iron, percent transferrin saturation and TIBC where as insignificant changes were found in MCH and MCHC. Fersolate-CM provided significant results on Hb gm%, RBC, PCV, MCV, MCH, serum iron, percent transferrin saturation and TIBC whereas insignificant change was found in MCHC. Trikatrayadi Lauha showed significant results on Panduroga and Iron Deficiency Anaemia (IDA).

23.  Preparation and Physico-Chemical Evaluation of Kshiramandura 
Ancient Science of Life  2010;29(4):7-12.
Mandura (Iron rust) is known by names lohkitta, malayas, ayomala, meaning waste of iron. Among different formulations prescribed for Parinamashoola (Peptic ulcer), in Ayurvedic classics Kshiramandura (Preparation of Iron rust in Milk) is one. Ancient authorities have given similar recipes of Mandura and these medicines are being successfully administered in the management of Peptic ulcer. In Parinamashoola (Peptic ulcer), Acharya Chakradatta mentioned Kshiramandura, as a formulation prepared by taking 384gms of Mandura Bhasma (Incinerated Iron rust), 3 Kg 73 gm of cow's urine and 768gms of cow's milk, boiled and administered in a dose of 500mg. To establish Physical and Chemical factors present in Mandura before and after purification and incineration, the preparation ofKshira mandura was attempted by adopting Quantitative and Qualitative methods. The drugwas identified by the qualities as described in the classics, viz., unctuous, heavy, hard and black in color and absence of hollow space. Mandura was heated in burning charcoal (600-800° c) and dipped in 5 liters of Cow's urine. This process was repeated 7 times, till the Mandura broke. This purified Mandura was then powdered and triturated with decoction ofTerminalia chebula, Terminalia belerica and Emblica officinalis (Triphala kashaya). Thereafter pellets were prepared and dried. The pellets were then sealed in crucibles and heated 30 times in a special type of furnace with temperature of 1000°c (Gajaputa method) to incinerate Mandura and prepare its ash (Bhasma). Cow's urine and milk were added to this Mandura Bhasma and Kshiramandura was prepared. When analyzed it showed 68.3 5% Ferric oxide, 0.66%MgCO3 and 1.32% CaCO3.

24.  Physicochemical characterization of Ayurvedic bhasma (Swarna makshika bhasma): An approach to standardization 
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.

25.  Bhasma : The ancient Indian nanomedicine 
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.
