2.  Comparative anti-inflammatory and analgesic activities of leaf powder and decoction of Chirabilva [Holoptelea integrifolia (Roxb.) Planch]  
Ayu  2014;35(3):339-343.
Ethno-medical claims indicate that leaf of Holoptelea integrifolia (Roxb.) Planch is being used in pain, inflammatory conditions by the Koya tribes.
To evaluate and compare the anti-inflammatory and analgesic activity of leaves of H. integrifolia in powder and decoction forms.
Materials and Methods:
The leaves of H. integrifolia were made into powder and decoction form using guidelines mentioned in Ayurvedic Pharmacopeia of India. The anti-inflammatory activity of test drug was evaluated against carrageenan and formalin induced paw edema and analgesic activity with formalin induced paw licking and tail flick response using Wistar albino rats.
Administration of leaf powder showed insignificant inhibition of carrageenan induced paw edema at 1 h (21.62%) compared to the control group. Administration of decoction of leaves showed insignificant inhibition of carrageenan induced paw edema at 1 h (18.12%) and 3 h (9.78%). Administration of leaf powder decreased the paw edema at 24 h (37.65%) and 48 h (66.30%) while treatment with leaf decoction showed apparent decrease in paw edema at 24 h (13.68%) and 48 h (52.42%) but failed to reach at significant level of formalin induced paw edema in rats. The test drugs did not produce any effect on radiant heat induced pain in rats and formalin induced paw licking response.
Leaf decoction of H. integrifolia has better anti-inflammatory activity than leaf powder while they have not shown significant analgesic effects in both the experimental models.

3.  Consequences of excessive use of Amlarasa (sour taste): A case-control study 
Ayu  2014;35(2):124-128.
Palatability is an important factor for choice of food by an individual. Amlarasa (sour taste) is one of the main organoleptic entities in foods of present day, which always tempts the consumer to take it now and then. According to classical Ayurvedic texts, balanced intake of Amlarasa in diet helps to maintain physiological health, but its excessive intake produces some signs and symptoms such as dentine hypersensitivity, stomatitis, halitosis, heartburn, urticaria, papule and joint inflammation.
To establish the relationship between excessive use of sour predominant diets and signs/symptoms produced by it.
Materials and Methods:
A case-control survey study was designed wherein total of 178 volunteers were interviewed personally. Subjects with particular symptoms consider as a cases while healthy volunteers as controls. To measure the excessive intake of Amlarasa, quantity and frequency of common food articles such as mango, tomato, lime, butter milk, tamarind, curd, fermented items etc., are taken into consideration. Data was arranged in to 2 × 2 table and odd ratio was calculated for each symptom.
Odds ratio for dentine hypersensitivity, stomatitis, halitosis, heartburn, urticaria, papule and joint inflammation with 95% confidence interval were found 1.95 (0.97-3.93), 2.45 (1.12-5.40), 2.76 (0.96-7.98), 2.21 (1.09-4.53), 0.86 (0.32-2.32), 2.28 (1.02-5.05) and 4.85 (1.09-10.24) respectively.
Study reveals that Amlarasa is a risk factor for joint inflammation, dentine hypersensitivity, stomatitis, halitosis, heartburn and papules. Study supports the Ayurvedic classical claim regarding Atiyoga of Amlarasa.

4.  Role of thin-layer chromatography in ascertaining Kashaya Rasa (astringent taste) in medicinal plants on the concept of Samana and Vichitra Pratyayarabdha principles of Ayurveda 
Ayu  2014;35(2):179-183.
Pharmacodynamics, in Ayurveda has been described in terms of Rasadipanchaka. Rasa, on one side indicates the Bhautika composition of the drug and on the other side predicts the action. Different analytical techniques, pharmaceutical processes are being used in Ayurveda for the purpose of standardization of raw drugs.
In this study an attempt has been made to apply chromatographic technique in determination of Kashaya (astringent) Rasa (taste).
Materials and Methods:
Two important Kashaya dominant drugs Kulattha (Dolichos biflorus Linn.) and Kanchanara (Bauhinia variegata Linn.), falling under Vichitra and Samana Pratyayarabdha category respectively, were subjected to physicochemical parameters and qualitative tests followed by High-Performance Thin-Layer Chromatography (HPTLC). In light of chromatographic fingerprinting; sample preparation protocol is modified to incorporate taste threshold in correlation. Column chromatography is used for first-level discrimination technique followed by HPTLC. Kashaya Rasa Dominant Zone (KsRDZ) was separated and subjected to TLC fingerprinting. The KsRDZ fraction was designated as Botanical Reference Material (BRM) in further analysis.
Ash value, Alcohol and water soluble extract value were more in B variegata as compared to D biflorus. Presence of tannin in both the samples was confirmed through qualitative test. The KsRDZ fraction separated at Rf 0.46 and 0.48 for Kulattha and Kanchanara respectively.
The results showed that the planner chromatography technique seems very useful when BRM hypothesis was adjunct to method that explains the categorization according to traditional Rasa domain classification method.

Limphonia rugosa Roth. (Merr.), family-Scrophulariaceae is considered as a botanical source of classical Ayurvedic drug Bhringaraja by the traditional practitioners of Odisha and is being used for the management of various disorders.
To study the antimicrobial activity of leaf of L. rugosa.
Materials and Methods:
Methanol extract of L. rugosa leaf (LRLM) has been studied, at various (5, 25, 50, 100, 250 μg/ml) dilutions, against medically important human pathogenic bacteria (two Gram-positive Staphylococcus aureus, Streptococcus pyogenes and two Gram-negative-Escherichia coli, Pseudomonas aeruginosa) and two fungal strains (Aspergillus niger, A. clavatus, Candida albicans) by using the agar disc diffusion method. A zone of inhibition of extract was compared with that of different standards such as ampicillin, ciprofloxacin, norfloxacin and chloramphenicol for antibacterial activity and nystatin and griseofulvin for antifungal activity.
The antibacterial and antifungal activities of the LRLM increased linear with the increase in concentration of extracts. When compared with standard drugs, the results revealed that, for bacterial activity S. pyogenes and S. aureus were more sensitive and in fungal activity C. albicans was more inhibited. The range of growth inhibition zone for all the sensitive bacteria was 11-20 mm and 13-19 mm for fungal strains.
Methanolic extract of L. rugosa leaf is having antibacterial and antifungal activities.

7.  Phytochemical evaluation of the wild and cultivated varieties of Eranda Mula (Roots of Ricinus communis Linn.) 
Ayu  2013;34(2):200-203.
In Ayurveda, the roots of Eranda (Ricinus communis Linn.) are used in the treatment Amavata (rheumatism), Sotha (inflammation), Katisula (backache), Udararoga (disease of abdomen), Jwara (fever), etc, Due to high demand, root of the cultivated variety is mainly used in place of wild. But, a comparative phytochemical profile of both varieties is not available till date. Considering this, a preliminary study has been done to ensure basic phytochemical profile of both the varieties. Preliminary physicochemical parameters, phytochemical screening, quantitative estimation of alkaloid, high-performance thin layer chromatography (HPTLC), and heavy metal analysis were carried-out in the study. Analysis of physicochemical data reveals no significant difference in between both varieties of roots, while alkaloid was found to be more in cultivated variety (0.34%) than wild one (0.15%). Though, the analytical profiles are almost identical, except the quantity of alkaloid; inferences should be made through well designed pharmacological and clinical studies.

8.  Analgesic activity of Nelsonia canescens (Lam.) Spreng.root in albino rats 
Ayu  2013;34(2):226-228.
Present study was undertaken to evaluate analgesic activity of root of Nelsonia canescens (Lam.) Spreng, a folklore medicinal plant used as the one of the source plant of Rasna. Study was carried out at two dose levels (270 mg/kg and 540 mg/kg) in albino rats. Analgesic activity was evaluated in formalin induced paw licking, and tail flick methods whereas indomethacin and pentazocine were used as standard analgesic drugs, respectively. At both the dose levels, test drug non-significantly decreased paw licking response at both time intervals. In tail flick model, the administration of the test drug increased pain threshold response in a dose dependent manner. In therapeutically equivalent dose level, analgesic activity was observed only after 180 min while in TED ×2 treated group analgesia was observed at 30 min and lasted even up to 240 min. The results suggested that N.canescens root possess moderate analgesic activity.

11.  Effect of Purificatory Measures Through Cow's Urine and Milk on Strychnine and Brucine Content of Kupeelu (Strychnos Nuxvomica Linn.) Seeds 
Strychnos nux vomica Linn.(Loganaceae) commonly known as Nux vomica (Kupeelu), is a poisonous plant and its seeds are used widely in Ayurvedic system of medicine since time immemorial. Ayurveda advocates that nux vomica seeds are to be administered in therapeutics only after going through certain purificatory measures (Shodhana). There are more than six media: cow's urine (Go mutra), cow's milk (Go dugdha), cow's ghee (Go ghrita), Kanji (thin gruel), castor oil (Eranda taila) and fresh ginger juice (Ardraka swarasa) etc., which have been reported in different classical texts of Ayurveda for proper processing of nux vomica seeds. In this study, an attempt has been made to purify the seeds by using three different methods as described in ancient treatise by using cow's urine and cow's milk as media alone and together. This study revealed that all the methods studied reduced the toxicity of strychnine and brucine contents in comparison to the raw seeds as determined by HPTLC. Out of these three methods maximum reduction in strychnine and brucine contents was found when the seeds were purified by keeping them in cow's urine for seven days followed by boiling in cow's milk for three hrs.

16.  A comparative antibacterial evaluation of raw and processed Guñjā (Abrus precatorius Linn.) seeds 
Ancient Science of Life  2012;32(1):20-23.
Seed of Guñjā (Abrus precatorius Linn.), a known poisonous drug, is used extensively in various ayurvedic formulations with great therapeutic significance. Ayurveda recommends the administration of Guñjā in diseases like Indralupta (alopecia), Śotha (edema), Kṛmi (helminthes), Kuṣṭha (skin diseases), Kaṇḍu (itching), Prameha (urinary disorders) etc., after being treated with specific Śodhana (purification) procedures.
To assess the antimicrobial action of of raw and Śhodhita (Processed) Guñjā seeds
Guñjā seeds after being processed with Godugdha (cow's milk), Nimbu swarasa (Lemon juice), Kāñjī (Sour gruel) and water, as the media, were evaluated for its antibacterial effect against clinically important bacterial strains using agar well diffusion method.
Aqueous extracts of raw seeds of Guñjā exert its antibacterial effect on both Gram positive, as well as Gram negative bacteria but none of the Śodhita Guñjā seeds showed any bactericidal effect on any bacterial strains. Chloroform extracts of all the Śodhita Guñjā seed extracts could inhibit bacterial growth but with variations
The study displayed that chloroform extracts of raw and śodhita samples for bacterial study were much sensitive than the aqueous extracts.

18.  Anti-inflammatory activity of two varieties of Pippali (Piper longum Linn.) 
Ayu  2012;33(2):307-310.
The present study has beenundertaken to evaluate the anti-inflammatory activity of two varieties of Pippali in acute and sub-acute experimental models of inflammation in albino rats. Four different market samples of each variety of Pippali were procured from different regions of India. The samples collected from South India which have given more extractive values were selected for screening of anti-inflammatory activity. Randomly selected animals were divided into four groups of six animals each. The test drugs were administered orally at a dose of 200 mg/kg and the activity was compared with standard anti-inflammatory drugs in both models. Among the two different test samples studied, it was found that Chhoti variety of Pippali suppressed inflammation of both acute and sub acute phase, while Badi variety of Pippali only of acute phase. Thus for the therapeutic utility, Chhoti variety of Pippali may be considered over the Badi variety.

19.  Pharmacognostical evaluation of leaf of Bada Rasna [Nelsonia canescens (Lam.) Spreng.; Acanthaceae] 
Ancient Science of Life  2012;31(4):194-197.
Nelsonia canescens (Lam.) Spreng. (Acanthaceae), a well-known plant in traditional systems of medicine, known as “Bada Rasna” by the traditional practitioners of Odisha, is being used as Rasna for managing pain and inflammation. The detailed macroscopic and microscopic characters of the plant, except its root, are lacking. Hence, it was thought worth to study the leaves of the plant for its detailed morphological and microscopical characters, by following the standard pharmacognostical procedures. The study shows the presence of diacytic stomata in the lower epidermis of lamina, microsphenoidal and prismatic crystals of calcium oxalate in the mesophyll cells, simple and glandular trichomes. The observed major diagnostic characters of the leaf may find useful for its standardization.

20.  Effect of Shodhana (processing) on Kupeelu (Strychnos nux-vomica Linn.) with special reference to strychnine and brucine content 
Ayu  2011;32(3):402-407.
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.

21.  Importance of Media in Shodhana (Purification / Processing) of Poisonous Herbal Drugs 
Ancient Science of Life  2010;30(2):54-57.
In Ayurveda, a series of pharmaceutical procedures which converts a poisonous drug into a therapeutically very effective medicine for various ailments is termed as Shodhana. Various medias are being used for processing the herbal poisonous drugs, are quite interesting to understand with modern scientific technology. The analysis of media before and after Shodhana (purification /processing) will give clear rationale behind the selection of the particular media for the particular drug. The change that takes place during the Shodhana process can be explored by modern analytical methods. Researchers have proved the presence of strychnine and brucine in milk after Shodhana of Nux-vomica highlighting the role media for Shodhana. Importance of Shodhana, the role of media used for Shodhana process of few poisonous drugs is dealt briefly with scientific view.

22.  Critical analysis of herbs acting on Mutravaha srotas 
Ayu  2010;31(2):167-169.
Ayurveda has given prime importance to Mutravaha srotas (urinary system) and Srotogata Vikaras (urinary disorders). Being a system responsible for homeostasis of fluids in the body it also detoxifies the body by eliminating certain waste products through urine. When diseased, people produce symptoms such as, increased or decreased urine production, painful maturition, formation of stones, and thereby obstructed micturition, increased frequency of micturition, and so on. There are many herbs with varied actions specifically aimed at mitigating urinary system disorders. Drugs such as Jambu, Amrasthi, and the like, reduce the increased flow of urine, and hence, are considered as Mutrasangrahaneeya, whereas, drugs like Ikshu, Kustha, and so on, increase the flow of urine, and hence, are considered as Mutravirechaneeya. There are drugs like Padma, Utpala, and so on, which impart normal color to the urine and are known as Mutravirajaneeya dravyas. Asmarighna dravyas break down the calculi and remove them through the urine. These dravyas, when used under proper direction, help in relieving the pain and apathy caused by the disease.
