Makaradhwaja is an important Kupipakwa Rasayana. It is prepared by using Swarna (gold), Parada (mercury) and Gandhaka (sulfur) in different ratios, i.e. 1:8:16, 1:8:24 and 1:2:4, respectively. The amount of Gandhaka in the Jarana process is directly proportional to the increase in therapeutic efficacy and reduces the toxicity of the product. Specific temperature pattern for the preparation of Makaradhwaja has been followed. In the present study Swarna, Parada and Gandhaka were taken in the ratio 1:8:24, respectively, and 12 h of heating for a specified amount of Kajjali (i.e., 400 g) in a Kacha Kupi 1/3rd of its capacity. There are some controversies regarding the form of Swarna (i.e., Swarna Patra Swarna Varkha or Swarna Bhasma) used in the preparation of Makaradhwaja. Therefore, in the present study, the samples of Makaradhwaja were prepared by Swarna Patra, Varkha and Bhasma in different batches. It was found that the use of Varkha produced a good-quality product along with the maximum amount of gold, i.e. 268 ppm, in comparison with Patra, i.e. 131 ppm, and Bhasma, i.e. 19 ppm, respectively.

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 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.

Guduchi (Tinospora cordifolia wild miers) is a well-known medicinal plant, which is abundantly used in different ayurvedic formulations utilizing varieties of media. The drug has properties like Rasayana (rejuvenating property), Krimighna (anthelmintics), and Kushtghna (used in skin disorders), as described in ayurvedic literature. Taila (oil) and Ghrita (ghee) are used as media in Ayurvedic Sneha (oleaginous) formulations. Both the test drugs, Guduchi Taila and Ghrita, are prescribed in Vatrakta (gout) and also indicated for Kushtha (skin disorder). With all these details, the Guduchi Taila and Guduchi Ghrita samples, prepared by using Taila and Ghrita as media, have been subjected to comparative pharmacological investigations, to assess the impact of the media on the expression of pharmacological activity. The formulations have been evaluated for immunomodulation, anti-inflammatory, and anti-stress activities. Both the formulations have been found to be active in most of the experiments, however, with the change of media, their results vary at different levels. Taila prepared from Guduchi was found to have an immunostimulating activity. The formulation prepared with Ghrita exhibited an anti-stress effect with an immunosuppressing activity.

Rasamanikya is a famous drug, frequently used by Ayurvedic physicians for Vata-Kaphaja diseases like Shwasa, Kasa and Kushtha (Skin disorders). Various methods of preparation have been found described in Rasa classics. Generally it is prepared by Shuddha Haratala which is kept between two thin transparent Abharaka Patra (mica sheets) in small scale and in sharava for large scale, heated up to desired level. There are so many methods and different liquid media have been found described for Shodhana of Haratala. Therefore the methods of preparation of Rasamanikya and Shodhana process of Haratala have been validated through various experiments. Tankana-treated Haratala (T. Treated) is found best for Shodhana process and final product too i.e. Rasamanikya in terms of pharmaceutical standards i.e. Ruby in colour, along with reproducibility of fixed quality.

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.

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.

Swarna-Vanga (SV) is a famous Kupipakva metallic preparation, which are therapeutically used as rejuvenator, anti-diabetic, and for testicular regeneration (Spermatogenesis) etc since 18th century. It contains Parad (mercury-Hg), Vanga (tin-Sn) and Gandhaka (Sulphur-S) in major amounts and our ancient author use different proportion of mercury in SV with respect to tin. So, in present study an attempt has been made to evaluate testicular regeneration property of SV with its safety and efficacy on albino rats.
1. Pharmaceutical Study: Preparation of SV in different proportion of Sn:Hg as 1:1,1:1/2, 1:1/4, 1:1/6. 2. Experimental Study: a) Toxicity study of SV for short (14 days) and long(40 days) duration in different doses, b) Regeneration property of SV on induced CdCl2 (Cadmium Chloride) testicular germinal epithelium of albinorats.
SV is a metallic preparation which contains mercury, tin and sulphur in major amount and the best product of SV is made by half of the mercury with the tin. SV does not show any toxic effects on therapeutic dose (12.5-25 gm/body weight of albino rats) but show some toxic effects on higher dose in longer duration. The ability of SV in generation of testicular germinal epithelium is seen on partial damaged testis which is produced by inducing CdCl2.
1) The presence of mercury at least in half proportion to tin in is necessary in making the SV of good standards, 2) SV is not toxic in therapeutic dose and is slightly toxic on higher doses in long duration, 3) SV has the property to regenerate partially damaged testicular tissue.
Civanar amirtam is a siddha herbo- mineral formulation prescribed for rheumatism, bronchial asthma, tuber culosis and leprosy. Of the nine ingredients which constitute the preparation, four are inorganic and the others are plant drugs, Attempts have been made to chemically analyse and to identify the presence of each ingredient in the medicine to lay down standards. The identification of various chemical constituents present in the plant drugs using TLC technique by comparison with authentic chemicals, along with the physico-chemical parameters and quantification of inorganic ions established the presence of each ingredient. The parameters presented can be considered viable for prescribing dependable standards to this preparation.
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.
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.
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.
The method can be suggested for effective quality control of herbal products and will establish standardization parameters for identification, quantification and purity determinations.
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.

Mattan tailam, a siddha herbo-mineral oil was prepared and chemically analysed. The physico chemical parameters and thin layer chromatographic pattern were evolved to lay down the standards, The data presented can be used for fixing standards to mattan tailam.
Various types of stress not only harm the mental function, but also cause diseases by weakening body defenses. Rasayana therapy has an advantage over the conventional Kayachikitsa treatment in such conditions, as it is capable of counteracting the stress, promote the adaptogenic abilities of the body, enhance mental endurance, etc. These are the some of parameters for evaluation the rasayana effect of a drug, therefore the same have been studied to assess the rasayana effect of Ranahamsa Rasayanaya (RR). Experimental models such as forced swimming induced hypothermia and stress induced gastric ulcer formation have been carried out befitting on Charles Foster strain albino rats to determine the rasayana effect of RR. Statistically highly significant decrease in forced swimming induced hypothermia and non-significant decrease in gastric ulcer formation were observed in the treatment groups, when compared to the stress control group. These results show the probable adaptogenic and anti-stress activities of the test drug. The study results support the claims made by the Sri Lankan traditional practitioners that, the test drug is a potent rasayana formulation.

At present there are effective drugs in eradicating microfilariae but treatments to control the progression of manifested filariasis, periodic adenolymphangitis (ADL) and lymphedema are not available in conventional system of medicine. So far National Ayurveda Research Institute for Vector-borne diseases, Vijayawada, has conducted many clinical trails on manifested filariasis patients with the classical Ayurvedic herbal, herbo-mineral drugs and found significant results on ADL, lymphedema and other acute and chronic clinical manifestations. An effort has been made to find the effect of Kuberaksha Patra Churna [Caesalpinia bonduc (L.) Roxb.], Vriddhadaru Mula Churna [Argyreia nervosa (Burm.f.) Boj.] and Kandughna Taila (oil prepared from 10 Ayurvedic drugs) in manifested filarial patients. Based on inclusion criteria 133 patients were included in three groups (45 in Gr.I, 45 in Gr.II and 43 in Gr.III) and 120 patients completed the study (40 in each group). In Gr. I Argyreia nervosa (Burm.f.) Boj. root powder, Caesalpinia bonduc (L.) Roxb. leaf powder mixed equally was given in the dose of 5 g twice a day for 30 days. In Gr.II along with Gr. I internal drugs Kandughna Taila was applied externally in sufficient quantity once a day for 30 days. Gr. III is a control study with Ayurvedic established drug ‘Nityananda Rasa’ 1 tablet thrice daily for 30 days. Group I and II drugs showed highly significant effect on lymphedema, lymphadenitis, lymphangitis, pain, tenderness, heaviness, deformity, fever and rigors (P<0.0001). Group III drug showed highly significant (P<0.0001) effect on lymphedema, deformity and heaviness; statistically significant (P=0.0018) on pain and tenderness; Significant effect on fever (P=0.0290), rigor (P=0.0290) and in lymphangitis (P=0.0384) and non-significant effect on lymphadenitis (P=0.1033). On statistical analysis effect of treatment on Hb and eosinophil count was found non-significant in three groups. On ESR, effect of treatment was found significant in Gr. III and non-significant in Gr. I and Gr. II.

Sheetada is the early stage of periodontal diseases. This occurs due to negligence of oral hygiene, changing life-style, habits, and addictions. It is Kapha Rakta Pradhana Vyadhi. In modern dentistry papillary or marginal gingivitis can be correlated with Sheetada, on the basis of similarities in symptoms, involvement of anatomical structure, etiology and prognosis. The epidemiological studies conducted by American Academy of Periodontology shows that gingivitis of varying severities is nearly universal. It is estimated that over 80% of the world's population suffers from gingivitis. In this clinical study, 106 patients were registered among them 103 completed the treatment and were randomly divided by lottery method into two groups. In Group-A, Dashana Samskara paste local application on gums and in Group-B, Dashana Samskara Choorna Pratisarana on gums was given. After enrollment of the patients in the study cardinal symptoms of Sheetada (gingivitis) such as, Raktasrava, Krishnata, Prakledata, Mriduta, Mukhadaurgandhya, and also the objective criteria such as oral hygiene index, Gingival Index (GI-S), and Gingival Bleeding Index (GBI-S) were studied before and after the treatment. While considering comparative effect on subjective parameters such as Raktasrava, Dantamamsa Shiryamanata, Shotha and Chalata statistically significant results were obtained in Group-A than Group-B. In objective parameters such as, GI-S and GBI-S also showed statistically significant results in Group-A. Observations in follow-up study confirmed that the recurrence rate in the Group-Awas significantly lesser than the Group-B.

Diabetic population is more than 245 million worldwide and expected to be b380 million by 2025. One of the main causes of increasing rate of diabetes is stress and tension in day-to-day life, disturbing the homeostasis of positive and negative emotions to initiate pathophysiology of stress-induced diabetes. In the present study, in Group A of 34 patients, a herbo-mineral compound containing Shuddha Shilajatu, Shuddha Guggulu, Vijayasara Ghana, Saptarangi Ghana, and Triphala Ghana was administered in the dose of 3 gm/day in three divided doses with luke-warm water before meal for the duration of 8 weeks, which significantly relieved symptoms (60.52%) like Prabhuta Mutrata (54.55%), Avila Mutrata (66.67%), Daurbalya (61.36%), Shrama (59.32%), etc. with fasting blood sugar (4.05%) and postprandial blood sugar (9.95%). In another series of 34 patients (Group B), where psychological health promoting drug Shankhapushpi was administered in the dose of 1.5 gm/day in three divided doses for 8 weeks along with herbo-mineral compound. The percentage relief was found to be more better on symptoms (71.13%) like Prabhuta Mutrata (76.92%), Avila Mutrata (83.33%), Daurbalya (75%), Shrama (70.37%), fasting blood sugar (18.04%) and postprandial blood sugar (27.75%). Group B showed better results on psychological parameters like disturbed Manasabhava (29.16%) and Brief Psychiatry Rating Scale (38.28%). The high significance of χ2 (15.50) on overall effect of therapy indicated better results in group B.

The drug optimization and understanding the mechanisms of action of drugs on the deregulation of cell cycle which is frequently considered as the cause of progression in cancer can provide important insights for new cancer treatment strategies. The drug LAS02 is a herbo mineral drug prepared as per ancient Ayurvedic literature.
In this study the effect of LAS02 was studied by analyzing the effect on cell cycle by flow cytometery on cancer cell lines breast cancer (MCF7), cervical cancer (HELA), colon cancer (COLO 205) and prostate cancer (DU 145), procured from NCCS, Pune. The cells were treated by different doses of LAS02, and assay for proliferation was performed by MTT assay test, subsequently, these were analyzed by flow cytometer for cell cycle analysis.
The results showed inhibition of proliferation in MCF7 by 77% and HELA cells by 78% at dose of 500μg/ml in MTT assay. In cell cycle analysis for COLO 205 treated with LAS02, the percentage retention of the cells in G0/ G1 phase was 73.07% at 300μg/ml as compared to 52.16% in the control after 24hrs. In DU 145, treated with LAS02, cells that retained at G0/G1 phase were 79.28% at a dose of 400μg/ml after 48hrs; as compared to control of 62.41%. The apoptosis observed at 400μg/ml drug concentration was 43.51%.
The study shows that LAS02 acts as a potent anti cancerous compound by inhibiting proliferation as well as by inducing retention of cells in G0/G1 phase along with apoptosis significantly at in vitro level. Therefore, LAS02 arrests the cancerous cells in G0/G1 phase and prevented the entry of pre cancerous stem cells from G0/G1 phase into G2, the subsequent proliferative stage and inhibits cancer cells from completing the cell cycle. Such a finding is unique with this new drug, which holds a great promise as one of the most effective and safest cancerostatic drug.
Depressive illness has been considered as a problematic mental illness since antiquity. The treatment modalities of depressive illness are of many kinds. Use of Medhya Rasayana drugs is a unique method of treatment described in Ayurveda for depressive illness. Kushmanda (Benincasa hispida) is one of the Medhya Rasayana as described by Bhava Mishra. Ghrita is also considered as Medhya Rasayana by almost all Acharyas. Keeping this background Kushmanda Ghrita has been selected as a trial drug to treat the patients of depressive illness. The study was carried out in 35 clinically diagnosed cases of depressive illness by using DSM-IV diagnostic criteria of depressive illness. All patients were given 20 ml of Kushmanda Ghrita in two divided doses morning and evening with 40 ml of lukewarm water for a period of one month. It has shown statistically significant results with psychometric parameters–Hamilton depression rating scale (t = 24.36, P < 0.001), Hamilton anxiety rating scale (t = 26.20, P < .001), immediate memory span direct (t = 4.35, P < 0.001), and indirect test (t = 3.43, P < 01) along with clinical symptoms.

We report preliminary results from an ongoing series of experiments on lifespan extension by appropriately modified Ayurvedic rasayanas in animal models. Here data are presented indicating lifespan extensions of 51–55% (up to 70–95% in the pilot experiment) in a standard strain of Drosophila melanogaster (Oregon-K) using a standard rasayana (Ayurvedic herbal formulation for life-extension) suitably adapted for insects. In a first experiment, two groups of 20 unmated D. melanogaster strain Oregon-K kept at 22°C received either rasayana or standard yeast diet; days of death were recorded. Another experiment investigated possible sex differences; equal sized (N = 30) groups of similar males, females, and controls were compared. Life lengths of all controls were in the strain's usual range: in Experiment 1, control life lengths were minimum 40 to maximum 53 days; experimental group figures were 81–91 days; groups were completely separated, experimental group minimum life length being 28 days more than control group maximum life length, i.e., about 2.5 full distribution widths – a sign test for the null hypothesis yields p < 2–20, i.e., 10–6 as maximum p. Experiment 2 found no differences between life lengths of males and females; but the maximum life length of 30 controls (60 days in males and 66 days in females) was once again far shorter than the minimum life length of the 60 in the two experimental groups, strengthening the findings of Experiment 1. Despite group sizes being relatively small, results are conclusive: the rasayanas in question increase D. melanogaster strain Oregon-K life length. The complexity of the formulation suggests that multiple mechanisms are involved – worth further investigation.

Immunity plays a key role in maintaining the health of an individual. Therefore, the rational modulation of the immunity through psycho-neuro-endocrine-immune (PNI) axis is useful for the prevention as well as for the curing of the diseases. As immunomodulation is a parameter for evaluation of the rasayana effect of a drug, the same has been studied to assess the rasayana effect of Ranahamsa Rasayanaya (RR). Experimental models such as antibody formation against sheep red blood cells (SRBC) and cell mediated immunity (CMI) have been carried out befitting on Wistar strain albino rats to determine the immunomodulatory effect plus rasayana effect of RR. Statistically significant increase in body weight, nonsignificant increase in antibody formation against SRBC, highly significant decrease in CMI were observed in the treatment groups, when compared to the standard control group. These results show the probable immunomodulatory and anabolic activities of the test drug. Outcome of these studies validate the strong rasayana effect of the test drug claimed by the traditional practitioners of Sri Lanka.

The purpose of the present investigation was to prepare matrix tablets of naproxen using a hydrophobic polymer, i.e., Eudragit RLPO, RSPO, and combination of both, by wet granulation method. The tablets were further coated with different concentrations of Eudragit S-100, a pH-sensitive polymer, by dip immerse method. In vitro drug release studies of tablets were carried out in different dissolution media, i.e., 0.1 N HCl (pH 1.2), phosphate buffers pH 6.8 and 7.4, with or without rat cecal content. The swelling studies of the optimized formulation were carried out. The physicochemical parameters of all the formulations were found to be in compliance with the pharmacopoeial standards. The effect of dissolution medium on the surface of matrix tablet was determined by using Scanning Electron Microscopy technique. The stability studies of all formulations were performed as per ICH guidelines. The results demonstrated that the tablets coated with Eudragit S-100 (2% w/v) showed a sustained release of 94.67% for 24 h, but drug release increased to about 98.60% for 24 h in the presence of rat cecal content while the uncoated tablets released the drug within 5 h. With regard to release kinetics, the data were best fitted with the Higuchi model with non-Fickian drug release kinetics mechanism. The stability studies of tablets showed less degradation during accelerated and room temperature storage conditions for 6 months. The enteric-coated Eudragit S-100 coated matrix tablets of naproxen showed promising site-specific drug delivery in the colon region.

Mineral drugs play an important role in Ayurvedic therapeutics. Looking to the superiority of the metals and minerals to that of herbal and animal drugs, the Rasavaidyas went on experimenting clinical trials over lot of metals and minerals and systematically separated some of them which were exclusively active therapeutically. Swarnamakshika is one such mineral which after proper purification and incineration become highly potent and utilised for diseases like Jwara, Pandu, Prameha, Shwasa, Kasa, Kushtha, Anidra, Apasmar etc.

There is insufficient scientific data on the medical management options for idiopathic oligoasthenoteratospermia (iOATs). We conducted a double blind, randomized, placebo-controlled trial to assess the efficacy and safety of the herbo-mineral supplement, Addyzoa®, in infertile men with iOATs. We also evaluated its effect on semen reactive oxygen species (ROS) levels, total antioxidant capacity (TAC) and DNA fragmentation index.
Materials and Methods:
Fifty infertile men with iOATS were recruited into an institutional ethics committee approved protocol from April to August 2009. Randomization was done using numbered, identical containers. Baseline semen samples were evaluated for routine parameters, ROS level, DNA fragmentation index and TAC. Drug/placebo was administered at a dose of two capsules twice a day for 3 months. All parameters were reassessed at 3 months and clinical side-effects were recorded. The study was registered with the Clinical Trials Registry of India and is available at www.ctri.in as study protocol number CTRI/2009/091/000551.
Forty-four subjects completed the study, 21 in the drug arm and 23 in the placebo arm. There was no difference in baseline parameters between the two groups. Men in the drug group had significant improvement in mean total motility from 23.2 ± 17.3% to 33.4 ± 23.2% (P-value: 0.008) and mean progressive (Type A+B) motility from 15.7 ± 12.6% to 22.6 ± 18.0% (P-value: 0.024). ROS, TAC and DFI did not change significantly in either group and did not show any correlation with other semen parameters.
Treatment with Addyzoa resulted in a significant improvement in total and progressive motility in the semen of men with iOATs after 3 months of therapy. There was no change in the sperm concentration, ROS, DFI or TAC levels.

The aim of the present study is to prepare and characterize Naga bhasma on structural and elemental basis to address the role of the raw materials used during the preparation, compound form of the lead bhasma, nature (crystalline/amorphous) and crystallite/particle size of the drug. The study also covers the toxicological effect of the drug on albino rats. It was found that drug contains lead in nano-crystalline (~60 nm) lead sulfide form (Pb2+) associated with the organic contents and different nutrient elements coming from the herbs used during the preparation. Naga bhasma prepared was found to be totally safe in histopathology study on rats at a dose of 6 mg/100 g/day. The different characterization techniques used present a role model for the quality control and standardization of such kinds of herbo-metallic medicines.
