3.  Screening of selected single and polyherbal Ayurvedic medicines for Antibacterial and Antifungal activity 
Ancient Science of Life  2010;29(3):22-25.
The present study deals with antimicrobial activity of ayurvedic drugs containing single herb (Amalaki Choorna and Yastimadhu Choorna) and combination of herbs (DN-90 and Asanadi Kwatha Choorna). Disc diffusion method was used to assess antibacterial activity and antifungal activity was tested using Poison food technique. Absence of bacterial growth around the discs impregnated with the aqueous extracts of drugs and reduction of fungal growth in poisoned plates indicated antimicrobial activity. Further, the results of antibacterial activity of Amalaki choorna were comparable with standard drug Streptomycin. Asanadi Kwatha Choorna inhibited bacteria to more extent than Yastimadhu choorna and DN-90. Among fungi tested, more antifungal activity was observed against Mucor sp. The antimicrobial activity of drugs tested could be due to active principles present in them.

5.  Pharmaceutical preparation of Saubhagya Shunthi Churna: A herbal remedy for puerperal women 
Background:
In the last few decades, there has been exponential growth in the field of herbal remedies. Pharmacopoeial preparations like avleha or paka (semi-solid), swarasa (expressed juice), kalka (mass), him (cold infusion) and phanta (hot infusion), kwatha (decoction) and churna (powder) form the backbone of Ayurvedic formulations. Newer guidelines for standardization, manufacture, and quality control, and scientifically rigorous research will be necessary for traditional treatments. This traditional knowledge can serve as powerful search engine that will greatly facilitate drug discovery.
Purpose:
The aim of the present study is to standardize Saubhagya Shunthi Paka in churna (powder) form. The powder form makes this traditional drug more stable for long-term storage and hence, easier to preserve.
Materials and Methods:
Saubhagya Shunthi Paka is an ayurvedic formulation containing Shunthi (Zingiber officinalis) as one of its chief ingredients. The basic preparation of this drug is a semisolid. We checked the microbial load and nutrient values (using International Standard IS and Association of Official Analytical chemists AOAC methods)
Results:
The powdered form of Saubhagya Shunthi Churna yielded a weight loss of approximately 17.64% of the total weight of ingredients. The total energy of Churna (calculated based on nutrient content) was found higher over Paka.
Conclusion:
Saubhagya Shunthi Churna may be a good therapeutic and dietary medicine for Indian women, which may be easily prepared at home.

6.  Standardization and quality control parameters of Dashanga Kwatha ghana tablet: An Ayurvedic formulation 
Herbal medicines have a long therapeutic history and are still serving many of the health needs of a large population of the world. However, the quality control and quality assurance still remains a challenge because of the high variability of chemical components involved. Herbal drugs, singularly and in combinations, contain numerous compounds in complex matrices in which no single active constituent is responsible for the overall efficacy. This creates a challenge in establishing quality control standards and standardization of finished herbal drugs. Many preparations have been mentioned in Ayurvedic text books for the treatment of Urdhwaga Amlapitta (non-ulcer dyspepsia). Dashanga Kwatha is one such known formulation. In this study, Dashanga Kwatha was converted into tablet form to increase the shelf life, make it easy to dispense, for dose fixation, etc. The Dashanga Kwatha Ghana tablet was subjected to organoleptic analysis, phytochemical analysis, and qualitative analysis to detect the presence of various functional groups, and to high performance thin layer chromatography (HPTLC) examination by optimizing the solvent systems. The investigation revealed the presence of tannins, mucilage, ascorbic acid, alkaloids, saponins, glycosides, flavonoids and carbohydrates mainly.

10.  Preparation of Dhatryarishta by Dhatri Swarasa and Dhatri Kwatha 
Ayu  2011;32(2):265-270.
Dhatryarishta has been described for the first time in Charaka Samhita, in the context of Panduroga. The same reference is available in Chakradatta, Bhaishajya Ratnavali, and Sahastrayogam too. Generally Dhatri Swarasa [Amalaki (Emblica officinalis Gaertn.)] is used in the preparation of Dhatryarishta as per classical reference, but fresh Amalaki is not available in every season, so in the present study, Amalaki Kwatha (decoction) is used instead of Swarasa. A total of 13 batches of Dhatryarishta were prepared, out of which nine batches were prepared with Dhatri Swarasa and four batches with Dhatri Kwatha. For Dhatryarishta prepared by using Dhatri Swarasa, three methods were applied and in Dhatryarishta prepared by using Dhatri Kwatha two methods were applied. The study revealed that Dhatryarishta could only be prepared by using Amalaki Swarasa as quoted in the classics and not by using Amalaki Kwatha.

12.  Pharmacognostic Standardization, Physico- and Phytochemical Evaluation of Amaranthus Spinosus Linn. Root 
Amaranthus spinosus Linn. (Amaranthaceae) is found throughout India. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian traditional system of medicine. Pharmacognostic standardization; physico-and phytochemical evaluation of the roots of Amaranthus spinosus was carried out, to determine its macro-and microscopical characters, and also some of its quantitative standards. Microscopical studies were done by using the trinocular microscope. Total ash, water-soluble ash, acid-insoluble ash, sulfated ash values, and alcohol-and water-soluble extractive values were determined for physico-chemical evaluations. A preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, the root showed cork, cortex, stellar region, and calcium oxalate crystals. Powder microscopy showed anamalous secondary growth in between the xylem vessels and Calcium Oxalate crystals in the cortex region. Total ash was approximately three times more than acid insoluble and water soluble ash. The ethanol soluble extractive was approximately the same as the water soluble extractive. Thin Layer Chromatography (TLC) of the Petroleum-ether extract using Benzene : Ethyl acetate (6 : 1), showed six spots. In the chloroform extract, using Benzene : Ethyl acetate (4 : 1) nine spots were seen, and in the ethanol extract, using Chloroform: Methanol (93 : 7), only four spots were observed, using Iodine vapor as a viewing medium. Phytochemically, the root exhibited terpenes, alkaloids, glycosides, and sugars. These findings might be useful to supplement information with regard to its identification parameters, which are assumed significant in the way of acceptability of herbal drugs, in the present scenario, which lacks regulatory laws to control the quality of herbal drugs.

13.  Phytochemical investigation and pharmacognostic standardization of Cissampelos pareira root 
Ancient Science of Life  2012;31(4):181-184.
Background:
In ethno-medicinal practices, the roots of Cissampelos pareira(Patha) are used in the treatment of various ailments related to urinary problems and skin infections, and in tumorinhibitor activity, antibacterial, antimalarial, diuretic activity,anticonvulsant activity etc., The main problem encountered in standardization of Ayurvedic drugs is proper identification of the source plant.
Materials and Methods:
The macroscopic features of each anatomical component have been observed by a high-resolution camera. The moisture content, total ash, acid-insoluble ash, and water—alcohol and ether extractive values of the powdered sampleswere determined by the method as per WHO guidelines. The phytochemical investigation of the methanolic extract of Cissampelos pareira root was performed by the standard chemical ltests and by TLC on silica gel G using solvent systems proposed by Harborne.
Result:
The microscopic characteristics showed the wavy epidermis with unicellular trichomes. Lignified xylem vessels, radial medullary rays, and prismatic calcium oxalate crystals had also been found. Phytochemical screening revealed that the Cissampelos pareira root extract contains terpenoids, alkaloids, tannins, amino acid proteins, and carbohydrates. Alkaloids and essential oil were detected in TLC of the Cissampelos pareira root extract developed using blends of methanol:concentrated ammonia (200:3) and n-butanol:acetone:water (3:1:1) and benzene:ethyl acetate:formic acid(9:7:4) as solvent systems for alkaloid whereas chloroform(100%), benzene (100%), chloroform:benzene(1:1),and ether:benzene(1:1) as solvent systems for essential oil.
Conclusion:
These findings will be useful toward establishing pharmacognostic standards on identification, purity,quality, and classification of the plant, which is gaining relevance in plant drug research.

15.  Botanical pharmacognosy of stem of Gmelina asiatica Linn 
Ancient Science of Life  2012;31(4):190-193.
Gmelina asiatica Linn (G. parvifolia Roxb.) is a large shrub or a small tree. Roots and aerial parts are used in Ayurvedic medicine and also have ethno-medical uses. Root is reported as adulterant to G. arborea roxb roots. Pharmacognostical characters of root were reported. Owing to the shortage of genuine drug and ever-increasing demands in market, it becomes necessary to search an alternative with equal efficacy without compromising the therapeutic value. Nowadays, it becomes a common practice of using stem. In case of roots phytochemical and pharmacological analysis of stem was reported. However, there is no report on the pharmacognostical characters of stem and to differentiate it from roots. The present report describes the botanical pharmacognostical characters of stem and a note to differentiate it from root. Hollow pith, faint annual rings in cut ends, alternatively arranged macrosclereids and bundle cap fibers, and presence of abundant starch grains and calcium oxalates in pith and in ray cells are the diagnostic microscopic characters of stem. Stem pieces can be differentiated from roots by absence of tylosis.

18.  Role of diet and lifestyle in the management of Madhumeha (Diabetes Mellitus) 
Ayu  2013;34(2):167-173.
From ancient to modern times, the perspective to visualize the management of Madhumeha (DM) has shifted from holistic to drug oriented. Therefore, until a few years ago, the revival of the holistic approach, the Ayurvedic diet, and lifestyle were not being much focused. This research work was planned to evaluate the extra effects of Ayurvedic Ahara and Vihara in the management of Madhumeha and to project them socially. A total of 30 patients were selected and divided into two groups. Group A was treated with Ayurvedic Ahara and Vihara with Varadi Kwatha and group B was treated with only Varadi Kwatha for 8 weeks. The study showed highly significant results in most of the parameters in both the groups. However, further trials with increased number of patients are needed to support the current observations.

19.  Clinical efficacy of “Bhadra Mustadi Paste” and “Nagaradi Kwatha Gandusha” in Shitada (Gingivitis) 
Ayu  2011;32(2):218-224.
Shitada is one of the Dantamulagata Rogas mentioned by Acarya Susruta under the heading of Mukha Rogas. It is characterized by symptoms like spontaneous bleeding, halitosis, blackish discoloration of gums, and so on. The symptomatology of Shitada can be compared with gingivitis, which is caused mainly by the accumulation of debris, plaque, and calculus at the tooth margin due to ignorance of oral care. It can progress into periodontitis – the disease in which the firmness, contour, and position of the gums are altered and teeth become mobile. The prevalence of gingivitis is as high as 50% in most of the population. In the present study, a total of 33 patients were registered in three groups. Bhadramustadi yoga has been used in paste form for local application along with Nagaradi Kwatha Gandusa in Group A and in powder form for Pratisarana along with Nagaradi Kwatha Gandusa in Group B. In Group C (Control) Sphatika Jala was used. The patients were diagnosed and assessed on the basis of Ayurvedic as well as modern classical signs and symptoms. Further assessment was done with the different indices used in modern dentistry. All the signs and symptoms were given a score depending upon the severity, to assess the effect of the drugs objectively. The effect of therapy was highly significant in group A in most of the signs, symptoms, and indices; and in group B it was highly significant in some signs and symptoms.

20.  Acute toxicity study of Vasaguduchyadi Kwatha: A compound Ayurvedic formulation 
Ayu  2013;34(3):327-330.
Vasaguduchyadi Kwatha is a compound Ayurvedic formulation, indicated for the treatment of liver diseases, especially for Kamala (jaundice) and Panduroga (anemia). However, till date, no safety profile of this formulation has been reported; hence, in the present study, freshly prepared and market samples of Vasaguduchyadi Kwatha were evaluated for acute toxicity. Acute toxicity test was evaluated as per OECD 425 guidelines with 5 000 mg/kg as limit test in Wistar strain albino rats. Test formulations were administered to overnight fasted animals and parameters like body weight, behavioral changes, and mortality were assessed for 14 days. Hematological and biochemical parameters were assessed on 14th day. Results showed no significant changes in terms of behavioral changes, mortality, and body weight. Both the samples did not affect any of the hematological parameters. However, increase in blood urea level was observed. This study shows that both the samples of Vasaguduchyadi Kwatha are relatively safe up to the dose of 5 g/kg. However, further chronic toxicity evaluation is necessary to establish its safety profile on chronic administration.

Ancient Science of Life  2012;32(2):107-111.
Background:
Ficus microcarpa L. fil. (Syn: Ficus retusa) (Moraceae) is well-known traditional medicinal plant. The bark is used for diverse health ailments in traditional and folklore remedies.
Aims:
The present study was undertaken to lay down pharmacognostical and phytochemical standards.
Materials and Methods:
Pharmacognostic studies on fresh, dried and powdered bark was carried out to determine it's morphological, anatomical, and phytochemical diagnostic features. Furthermore, major phytoconstituents were identified from the extracts with the help of high performance liquid chromatography (HPLC) study.
Results:
The morphology showed to be soft, brittle, rough, shallow vertical, irregularly oriented fissures, curved surface; with splintering, laminated fracture. Microscopically F. microcarpa showed all general characteristics of bark with some distinct differentiation. The phellem is thin and even, phelloderm few cell and rectangular and followed by smaller sclerides, the phloem rays are broad, multi-serrate and showed the scattered bundles of sclerides. The fluorescence and physicochemical standards for bark were established. HPLC analysis showed the predominant presence of therapeutically important phytoconstituents such as oleanolic, betulinic acid, lupeol, β-sitosterol, catechin, and gallic acid.
Conclusion:
The bark of F. microcarpa considered equivalent to other Ficus species, such as Ficus virens, Ficus infectoria, Ficus arnottiana, Ficus lacor, and Ficus talboti. However, there is no pharmacognostical and phytochemical reports on F. microcarpa to authenticate and differentiate it from similar species. Present work has described pharmacognostical and phytochemical characteristics of F. microcarpa and diagnostic features to differentiate it.
