Brahmi is a well-known herbal drug having an effect on brain as a memory enhancer. Bacopa monnieri (L.) Pennel and Bacopa floribunda (R.Br.) Wettst are both marketed in the name of Brahmi. The present study differentiates Bacopa monnieri and Bacopa floribunda in morphology, transverse section (T.S.) of root and leaf, powder microscopy, and chemical constituents. Morphological characters show color difference in flower, stem and leaf and differences in microscopic study, organoleptic study, and powder characteristics. Morphologically, Bacopa monnieri leaf is fleshy and more succulent than Bacopa floribunda leaf. There is also a difference in the interval of the stem internodes of the two. Physico-chemical analysis revealed presence of 26% bacoside A in Bacopa floribunda leaf and 27% in Bacopa floribunda stem, which is higher than the bacoside A content in leaf (22%) and stem (18%) of Bacopa monnieri. However due to the hemolytic action of bacoside A, which is the toxic effect of the chemical constituent, it seems likely that Bacopa monnieri is more popular in regular use than Bacopa floribunda.

Aim of the study is to assess the antimicrobial activity Cassia fistula fruit pulp extracts on some bacterial and fungal strains. Hydro alcohol and chloroform extracts of Cassia fistula fruit pulp were evaluated for the potential antimicrobial activity. The antimicrobial activity was determined in both the extracts using the agar disc diffusion method. Extracts were effective on tested microorganisms. The antibacterial and antifungal activities of solvent extracts (5, 25, 50, 100, 250 μg/mL) of C. fistula were tested against two gram positive, two gram negative human pathogenic bacteria and three fungi, respectively. Crude extracts of C. fistula exhibited moderate to strong activity against most of the bacteria tested. The tested bacterial strains were Staphylococcus aureus, Streptococcus pyogenes, Escherichia coil, Pseudomonas aeruginosa, and fungal strains were Aspergillus. niger, Aspergillus. clavatus, Candida albicans. The antibacterial potential of the extracts were found to be dose dependent. The antibacterial activities of the C. fistula were due to the presence of various secondary metabolites. Hence, these plants can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities.

Vara Asanadi Kwatha (VAK) is a compound Ayurvedic formulation prescribed in the management of obesity. Pharmacognostical study counting both macroscopic and powder microscopy of raw drug exposed the quality and genuineness of all the constituents of VAK. Organoleptic features of coarse powder made out of the crude drugs were within the standard range. Specific gravity of the decoction was 1.0185 and pH was 5.5.Total solid content present in the Kwatha was 4.525% w/v, total ash 0.949% w/v, and acid insoluble ash was 0.052% w/v. Iron assay showed the presence of Fe2O3 as 0.065% w/v. Qualitative scrutiny demonstrated the presence of flavonoids and tannis. Thin Layer Chromatography (TLC) and High Performance Thin Layer Chromatography (HPTLC) were carried out after organizing appropriate solvent system in which maximum three spots were distinguished in TLC and nine spots in HPTLC and most of the Rf values were identical when done with different sample extractive methods. This shows the presence of certain definite constituents in the decoction and is helpful for the easy separation of these constituents.

Myopia is a major public health problem pertaining to eye that entails substantial societal, personal, educational, and economical impact. Various surveys in India have found the prevalence of myopia ranging from 6.9% to 19.7%. Myopia progression is irreversible and methods for the correction of myopia are not without complications. Myopia closely resembles Timira involving first and second Patala in terms of symptoms, anatomical structures involved, and the pathogenesis of the disease. The study is aimed at evaluating the efficacy of the Akshi-Tarpana procedure with Jeevantyadi Ghrita in fresh and old myopes. A total of 54 patients (108 eyes) having myopia ≥-6 D were registered for the study and divided into two groups (Group A, Akshi-Tarpana with Jeevantyadi Ghrita, and Group B, Akshi-Tarpana with plain Go Ghrita), by stratified sampling. The procedure was done in 5 sittings of 5 days each with an equal interval of 5 days between each sitting. A total of 22 patients in Group A and 18 in Group B completed the treatment. Obtained data were statistically analyzed using a t-test and the study reveals that objectively, 09.30% and 05.55% eyes were cured, 16.28% and 02.78% markedly improved, and 34.88% and 11.11% moderately improved in Group A and B, respectively.

Ten batches of Shirishavaleha were prepared by using Twak (Bark) and Sara (Heartwood) of Shirisha [Albizzia lebbeck Benth]. The adopted formulation was based on Shirisharishta of Bhaishajya Ratnavali. Though Shirisharishta has significant therapeutic effect in cases of Tamaka swasa, etc.; it has few difficulties during the pharmaceutical procedure like consuming long time, climatic influences etc. Considering these inconveniencies, the formulation composition has been converted in to Shirishavaleha. Avaleha has been prepared by using Twak and Sara of Shirisha. No significant differences were found in pharmaceutical aspects of both the samples of Shirishavaleha and the current method of preparation can be considered as standard. Attempts were also made to develop analytical profile of avaleha, which were almost similar in both the samples, except showing more Rf values in High Performance Thin Layer Chromatography profile of Sara group.

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.

Cordia dichotoma Forst.f. bark, identified as botanical source of Shlesmataka in Ayurvedic pharmacopoeias. Present study was carried out with an objective to investigate the antibacterial and antifungal potentials of Cordia dichotoma bark. Antibacterial activity of methanol and butanol extracts of the bark was carried out against two gram negative bacteria (Escherichia coli, and Pseudomonas aeruginosa) and two Gram positive bacteria (St. pyogenes and Staphylococcus aureus). The antifungal activity of the extracts was carried out against three common pathogenic fungi (Aspergillus niger, A.clavatus, and Candida albicans). Zone of inhibition of extracts was compared with that of different standards like Amplicilline, Ciprofloxacin, Norfloxacin and Chloramphenicol for antibacterial activity and Nystain and Greseofulvin for antifungal activity. The extracts showed remarkable inhibition of zone of bacterial growth and fungal growth and the results obtained were comparable with that of standards drugs against the organisms tested. The activity of extracts increased linearly with increase in concentration of extract (mg/ml). The results showed the antibacterial and antifungal activity against the organisms tested.

The present study was undertaken to evaluate diuretic activity of Euphorbia fusiformis root powder in Wistar strain albino rats. Randomly selected animals were divided into three groups of six animals each. The root powder was suspended in distilled water and administered orally at a dose of 90 mg/kg therapeutically equivalent dose (TED) and 180 mg/kg (TED × 02) to overnight fasted rats. The diuretic activity was evaluated by determination of urine volume and urinary electrolyte concentrations. Test drug showed significant increase in urine volume and urinary electrolyte excretion in a dose-dependant manner. Thus, from this study, it can be concluded that roots of E. fusiformis possess diuretic activity.

Kupeelu (Strychnos nux-vomica Linn.) commonly known as nux vomica is a poisonous plant used extensively in various ayurvedic formulations, with great therapeutic significance. Ayurveda recommended the administration of Kupeelu only after purification in different media like cow's urine (Go mutra), cow's milk (Go dugdha), cow's ghee (Go ghrita), Kanji (sour gruel), and so on. Apart from the classical methods some other methods are also adopted by the traditional practitioners using castor oil (Eranda taila), ginger juice (Ardraka swarasa), in the purification of Kupeelu seeds. In the present study an attempt has been made to purify the seeds by performing two different methods (one classical and another traditional) using Kanji and Ardraka
swarasa as Shodhana media. This study reveals that both the methods studied reduce the strychnine and brucine contents in comparison to the raw seeds as determined by high performance thin layer chromatography (HPTLC). After purification in Kanji and Ardraka swarasa, the strychnine content was reduced by 39.25% and 67.82%, respectively, and the brucine content in the purified seeds was also found to have decreased by 17.60% and 40.06%, in comparison to the raw seeds.

Plants of ethnomedicinal importance have contributed for the development of many new pharmacologically effective molecules/chemical entities to modern medicine. India, the country having one of the richest biodiversity of its flora in its forest, with numerous tribal inhabitants, is able to contribute a lot from ethnomedicine to the ailing humanity. Cordia macleodii Hook. (Boraginaceae), an ethnomedicinal plant has been highlighted for its wound healing, aphrodisiac and hepatoprotective activities. It is a medium-sized tree, known as Panki/Shikari by the tribals, rarely found in the forests of Orissa, Chhattisgarh and Madhya Pradesh. So far, the plant has been studied neither for its pharmacognostical characters nor for its pharmacological actions except its hepatoprotective activity. Hence, it has been selected for a detailed investigation which includes pharmacognostic study of its leaf to find out the diagnostic characters and preliminary physicochemical analysis. Results of the study will help in identifying the plant pharmacognostically. Presence of alkaloids, glycosides and tannins were found during the study.

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.

Gandhaka Rasayana is frequently used in the management of different skin disorders (Kushtha). It is a herbo-mineral preparation prepared by Shuddha Gandhaka Bhavit with 11 herbal drugs in a serial manner for eight times each. Therefore, it was used as a model drug and four samples were prepared by adopting different methods and media. The physicochemical parameters were evaluated. The effect of increasing the number of Bhavana (lavigation) on particle size of the drug was examined. Similarly, an attempt was also made to differntiate the structure (surface anatomy) of the drug with Bhavana and without Bhavana by using a very sophisticated x-ray photo electron spectrometer (XPS) study. Overall, a remarkable difference was observed in the samples with Bhavana and without Bhavana.
