Viruddha Ahara is a unique concept described in Ayurveda. The present article deals with the critical review of Viruddha Ahara referred in terms of food-food interactions, food processing interactions. Ayurveda clearly defines that certain diet and its combinations, which interrupts the metabolism of tissue, which inhibits the process of formation of tissue and which have the opposite property to the tissue are called as Viruddha Anna or incompatible diet. The food which is wrong in combination, which has undergone wrong processing, which is consumed in incorrect dose, which is consumed in incorrect time of day and in wrong season can lead to Viruddha Ahara. The article narrates the modern perspective of Samskar Viruddha, Veerya Viruddha, Samyoga Viruddha, and so on. It also enlists a variety of incompatible dietary articles consumed in today's day-to-day life and its hazardous effects on health.

Vamana Karma (therapeutic emesis) primarily a Samshodhana Karma (purification procedure) is one of the five Pradhana Karmas (chief procedures) of Panchakarma. It is mentioned in Ayurvedic texts that a person after Samyak Vamana (proper Vamana) experiences lightness of the body, Hrit (precordium), Kantha (throat/voice), and Shirah (head) and weakness. This procedure is effectively used in healthy and ailing persons for purification of body and extraction of Doshas (especially Kapha) in Ayurvedic system. It has been found worth to observe the physiological and biochemical changes during Vamana and after the procedure to understand the effect/safety margins of the procedure in healthy volunteers.

Infertility is a problem of global proportions, affecting on an average 8-12% of couples worldwide. Low sperm count (Oligozoospermia) is one of the main causes of male infertility and it is correlated with Kshina Shukra. The fruits of Gokshura (Tribulus terrestris. Linn) are considered to act as a diuretic and aphrodisiac; they used for urolithiasis, sexual dysfunctions, and infertility. Hence, it was planned to study the effect of Gokshura in the management of Kshina Shukra (Oligozoospermia), and to evade the preconception, a double-blind, randomized, placebo-controlled study was designed. In this study, eligible subjects between the age of 21 and 50 years, with a complaint of Kshina Shukra (Oligozoospermia), were randomized to receive either Gokshura granules or placebo granules for 60 days. The primary outcome measures were percentage changes in the Pratyatmaka Lakshanas (cardinal symptoms) of Kshina Shukra, Agni bala, Deha bala, Satva bala, the semenogram, and in the Quality of the Sexual Health Questionnaire. The placebo granules showed 70.95% improvement, whereas, the Gokshura granules showed 78.11% improvement in Rogi bala (Agni bala, Deha bala, Satva Bala, and the Quality of Sexual Health) and Rogabala (Semen Analysis and Pratyatmaka Lakshanas). The Gokshura granules have shown superior results in the management of Kshina Shukra, as compared to the placebo granules.

Herbal remedies have a long history of use for gum and tooth problems such as dental caries. The present microbiological study was carried out to evaluate the antimicrobial efficacy of three medicinal plants (Terminalia chebula Retz., Clitoria ternatea Linn., and Wedelia chinensis (Osbeck.) Merr.) on three pathogenic microorganisms in the oral cavity (Streptococcus mutans, Lactobacillus casei, and Staphylococcus aureus). Aqueous extract concentrations (5%, 10%, 25%, and 50%) were prepared from the fruits of Terminalia chebula, flowers of Clitoria ternatea, and leaves of Wedelia chinensis. The antimicrobial efficacy of the aqueous extract concentrations of each plant was tested using agar well diffusion method and the size of the inhibition zone was measured in millimeters. The results obtained showed that the diameter of zone of inhibition increased with increase in concentration of extract and the antimicrobial efficacy of the aqueous extracts of the three plants was observed in the increasing order - Wedelia chinensis0 < Clitoria ternatea < Terminalia chebula. It can be concluded that the tested extracts of all the three plants were effective against dental caries causing bacteria.

In Charak Samhita, all the treatment modalities have been classified broadly into six types, i.e., Langhana (depleting therapy), Brimhana (nourishing therapy), Rookshana (dehydrating therapy), Snehana (oleation therapy), Swedana (sudation therapy) and Stambhana (astringent therapy). Out of these six types, Rookshana is of the same importance as others but is used less frequently as main line of treatment. Since decades, Ayurveda treatment is considered most promising treatment for neurological disorders. Most of the neurological disorders are generally considered to be Vata Vyadhis in which Snehana Karma is recommended. In case of neurological disorders if symptoms are suggestive of Kapha dominance, then Rookshana must be done initially. Transverse myelitis is a neurological disease, which has an autoimmune process involved in its pathology. It is an acute, subacute, generally monophasic inflammatory disease of the spinal cord. In the present case of transverse myelitis, the patient was found having Kapha dominant symptoms such as coldness of feet, loss of appetite etc., and so the patient was subjected to Rookshana Karma in various forms. Just after 15 days, all these symptoms were subsided and tremendous improvement was found thereafter. The paraplegic patient under study was able to walk independently in just two and half months of treatment. All other typical features related to the disease were also improved. This particular case has proved the importance of Rookshana therapy in neurological disorders.

Taila Bindu Pariksha, an ancient method of urine examination for ascertaining the prognosis of diseases, was very popular in the medieval period, the use of which became obsolete after 17 ^th Century AD. Technique of this test is very crude and there are chances of variations in the observations. To revive this technique, it is necessary that the methodology of this test should be standardized so that the observations could be reproducible. To standardize the technique, apparently healthy volunteers were selected and various parameters were standardized for doing this test, i.e., shape and size of Patra (testing containers), volume of the urine, size of the oil drop, height of the oil drop from the surface of urine, variety of sesame oil, etc., Based on the literature, the parameters were changed one by one and observations were noted down. The whole method was recorded in the form of video clips for proper evaluation. The parameters standardized on the basis of observations can be considered as standard to be referred in future studies.

Tridoshas viz Vata, Pitta, and Kapha are responsible for health and disease depending on their normalcy and disequilibrium state. Improper usage of foods and drinks along with abnormal activities manifests diseases of respective Doshik predominance. Sira (vein) is the synonym of Srotas, keeping this in mind, Vatavaha Sira is correlated with Vatavaha Srotas, Pittavaha Sira with Pittavaha Srotas, Kaphavaha Sira with Kaphavaha Srotas, and Sarvavaha Sira with Sarvavaha Srotas. The purpose of detail understanding of Doshavaha Srotas is essential to understand the role of Doshas in the manifestation of diseases. One can easily predict by observing the color changes in particular area to be able to predict the predominance of Doshas in that area. Manifestation of a disease occurs in the body as a result of the defective Srotas favoring the Dosha-Dushya conglomeration. Hence, any defect in the Srotas must be corrected quickly for the restoration of normal health. Present article emphasis on the proper understanding of Doshavaha Srotas in a systematic manner to understand its root, causative factors, signs and symptoms, and diseases produced due to their vitiation.

Improper use of sense organs, violating the moral code of conduct, and the effect of the time are the three basic causative factors behind all the health problems. Computer, the knowledge bank of modern life, has emerged as a profession causing vision-related discomfort, ocular fatigue, and systemic effects. Computer Vision Syndrome (CVS) is the new nomenclature to the visual, ocular, and systemic symptoms arising due to the long time and improper working on the computer and is emerging as a pandemic in the 21 ^st century. On critical analysis of the symptoms of CVS on Tridoshika theory of Ayurveda, as per the road map given by Acharya Charaka, it seems to be a Vata-Pittaja ocular cum systemic disease which needs systemic as well as topical treatment approach. Shatavaryaadi Churna (orally), Go-Ghrita Netra Tarpana (topically), and counseling regarding proper working conditions on computer were tried in 30 patients of CVS. In group I, where oral and local treatment was given, significant improvement in all the symptoms of CVS was observed, whereas in groups II and III, local treatment and counseling regarding proper working conditions, respectively, were given and showed insignificant results. The study verified the hypothesis that CVS in Ayurvedic perspective is a Vata-Pittaja disease affecting mainly eyes and body as a whole and needs a systemic intervention rather than topical ocular medication only.

Population in an industrialized world is afflicted by urinary stone disease. Kidney stones are common in all kinds of urolithiasis. One distinguished formulation mentioned by Sushruta for management of Ashmari (urolithiasis) is Pashanabhedadi Ghrita (PBG), which is in clinical practice since centuries. Validation of drug is the requirement of time through the experimental study. In this study, trial of PBG has been made against ammonium oxalate rich diet and gentamicin injection induced renal calculi in albino rats. The calculi were induced by gentamicin injection and ammonium oxalate rich diet. Test drug was administered concomitantly in the dose of 900 mg/kg for 15 consecutive days. Rats were sacrificed on the 16 ^th day. Parameters like kidney weight, serum biochemical, kidney tissue and histopathology of kidney were studied. Concomitant treatment of PBG attenuates blood biochemical parameters non-significantly, where as it significantly attenuated lipid peroxidation and enhanced glutathione and glutathione peroxidase activities. It also decreased crystal deposition markedly into the renal tubules in number as well as size and prevented damage to the renal tubules. The findings showed that PBG is having significant anti-urolithiatic activities against ammonium oxalate rich diet plus gentamicine injection induced urolithiasis in rats.

Extremely diminutive published information is available on the mutagenic activity of Ayurvedic Bhasmas. Genotoxicity of few Bhasmas were reported on single maximum dose, but no reference is available on the sub-chronic level. Hence the present study was carried to generate and evaluate genotoxic potentials of Swarna Makshika Bhasma (mineral preparation) administered at therapeutic dose for 14 days. Chromosomal aberrations and abnormal sperm assay parameters were taken in this study. Cyclophosphamide (CP) was taken as positive group and results were compared. The results revealed a lack of generation of structural deformity in above parameters by tested drugs compared to CP treated group. Observed data indicate that the Bhasmas tested were non-genotoxic under the experimental conditions.

In the present era of stress, when lifestyle disorders are high on rise, premature ageing is also one of the most prevalent disorders. It is needed to study the external environmental psychological causative factors in premature ageing and stress. An observational study was carried out to evaluate the relationship of lifestyle, occupational and social factors and mental makeup in individuals diagnosed with premature ageing. A total of 108 patients of premature ageing and stress fulfilling the criteria of inclusion as per ageing scale were selected from outpatient Department of Panchakarma and Manasa Roga, Institute for Post Graduate Teaching and Research in Ayurveda, Gujarat Ayurved University, Jamnagar. The diagnosed patients of premature ageing were subjected to specialized proforma enlisting all the factors as well as ageing scale, Manasa Bhava Pariksha, and Manasa Vibhrama Pariksha. The method of survey was by a questionnaire about the points regarding the lifestyle causative factors. Maximum patients had shown signs of premature ageing with Mana-Buddhi-Smriti-Bhakti Vibhrama (100% each) and involvement of negative Manasa Bhava. The 78.70% patients in this study felt of having excess responsibility on them in family. The 52.77% patients had average good relationship with their family members, while remaining 47.22% narrated history of disturbed relationship. The center of stress was found to be at personal level in all patients; at family level in 73.14%; at professional or work level in 64.81%. Various external, occupational, social and familial factors play significant role in the pathology of premature ageing by disturbing the overall psychological status. This proves the link of Manasa affecting Sharira and vice versa with reference to modern contemporary concept of psycho-neuro endocrinology.

Tarakeshwara Rasa (TR) is an Ayurvedic herbomineral compound formulation used in the intervention of Prameha vis-à-vis diabetes mellitus. The present study was executed to establish a fingerprint for this unique formulation, which can be adopted by the Ayurvedic pharmacies for drug standardization. TR is a formulation prepared by the trituration of four ingredients Abhraka Bhasma (AB), Loha Bhasma (LB), Vanga Bhasma (VB) and Rasa Sindhura (RS) in equal quantities with honey for one day. Each of the ingredients were prepared according to the norms of Ayurvedic classical texts and by employing Electric Muffle Furnace as heating device for incineration. To ensure the proper preparation of Bhasmas, standard tests (Bhasma Pariksha) were employed. After Bhasma complies these tests, TR was prepared and subjected for qualitative analysis, X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) studies. LB, AB, VB, RS and TR were also studied for free metal presence by employing phosphomolybdic acid. Chemical analysis of TR reveals that it contains Fe, Sn, Hg, Al, Mn, Ca and Mg. XRD study indicates that TR contains Fe ₂ O ₃ (maghamite) in major phase and SnO ₂ (cassiterite), HgS, SiO ₂ , HgO in minor phases. SEM study revealed that the compound is an agglomeration of particles. The particle size was in between 0.5 and 2 μ. Free metal detection by phosphomolybdic acid revealed the absence of free metals in the final Bhasmas. This is the first study establishing the characterization of Tarakeshwara Rasa.

Bhattar Harichandra was the first commentator who wrote 'Charakanyasa' commentary on Charaka Samhita after completion of redaction process by Dridhabala. Two manuscripts of this commentary are available with number 9290 and 13092 in Asiatic Society of Kolkata and Government East Library, Chennai respectively. Yadavji opines that Bhattar Harichandra belongs to the period of Chandragupta - II (375 A.D. - 413 A.D.) while Acharya Priyavrat Sharma considers the period of Yashodharaman (6 A.D.) as the period of Bhattar Harichandra. As far as external evidence is considered Banabhatta another notable Sanskrit poet quoted Bhattar Harichandra in his work Harshacharitam. Banabhatta was contemporary to Chandragupta. Charaka Samhita enjoyed much reputation during Chandragupta Mourya - II period. Agnivesha Tantra was redacted during the period of Kanishka (2 A.D.) and then onwards it was referred by titles like Sahasanka and Vikramaditya. Among Navaratna (Nine gems), Shanku and Vaitala Bhatta are included. But in the authors opinion it should be commented as "Shankuvaitala" and "Bhatta". The name Bhatta in his context may be referring to Bhattar Harichandra. Based on the external evidences it may be concluded that Bhattar Harichandra was contemporary to Chandragupta period i.e. 375 A.D. - 413 A.D. (4th to 5th century).

Ghrita (ghee) is the foremost substance of Indian cuisine from centuries. Ayurvedic classics described eight kinds of ghee from eight different animal milk, among them ghee made from cow milk is said to be the superior and ghee of ewe milk is said to be the inferior and also detrimental to heart. The present study was undertaken to evaluate chronic administration of cow ghee (Go Ghrita) and ghee of ewe milk (Avika Ghrita) to experimental animals. Experiment was carried out on Wistar strain albino rats and study was done at two dose levels. The test drugs were administered orally for 45 consecutive days. Parameters, such as gross behavior, body weight, weight of important organs, total fecal fat content, electrocardiogram, serum biochemical parameters, and histopathology of different organs were studied. Both the test drugs did not alter the gross behavior, body weight, weight of organs, and cytoarchitecture of different organs to significant extent. Avika Ghrita at a low dose significantly decreased triglyceride content, significantly prolonged QTc and at both dose levels it significantly shortened the PR interval. This study shows chronic administration of Avika Ghrita and Go Ghrita has no marked differences between them except the QTc prolongation in Avika Ghrita. This may be the basis for the classics to categorize Avika Ghrita as Ahridya.

A group of five roots of small plants i.e., Shalaparni, Prshniparni, Brhati, Kantakari and Gokshura or Eranda is known as Laghupanchamula under Mishraka Varga (group of drugs). It is used as such or with Mahat Panchamula i.e., Bilva, Gambhari, Shyonaka, Agnimantha and Patala, constituting Dashamula, a well recognized and popular Ayurvedic preparation or as an ingredient of different dosage forms. Classical texts of Ayurveda differs regarding components of this Mishraka Varga. Four out of five drugs of Laghupanchamula are similar in all the Ayurvedic texts, but either Gokshura or Eranda is considered as the fifth drug. So a comphrenesive review of Veda, Samhita Grantha, Cikitsa Grantha and Nighantus, with regards to synonyms, contents, Guna- Karma, origin of variation in contents and possible thought behind two kinds of Laghupanchamula, to throw light for rational use of either Eranda or Gokshura under Laghupanchamula was conducted. It was observed that both the traditions were in practice however Acharya Kashyapa and Ravigupta were in view of Eranda as a fifth drug of Laghupanchamula where as Acharya Charaka, Sushruta, Vagabhatta, Yogaratnakara and Chakradatta are in favour of Gokshura. Infact, the variation in content depends on the need i.e Dosha, Dushya and Vyadhi.

Haritaki is praised as the best salutary drug which can be used in almost all ages of human life and is reputed for its Anulomana property. In Ayurveda, it has been mentioned that fruits of Haritaki when used in different forms give different type of actions. As the prime therapeutic utility of Haritaki is Anulomana, in the present study, two dosage forms of Haritaki fruits namely Churna and Vati were evaluated for intestinal transit time to evaluate its effect in two different dosage forms. Mature fruits were collected, authenticated, and processed as per classics to get Churna and Vati. Test drugs were administered in the dose of 550 mg/kg and evaluation on intestinal transit time was carried out by adopting kaolin expulsion test in mice. The results show that both the dosage forms of Haritaki significantly shortened intestinal transit time and between them Churna form is found to be better.

Medicinal plant materials are being adulterated in commerce due to many reasons such as similar morphological features, same name as written in classical text, presence of similar active principles in the substituted plant etc., that may badly affect the therapeutic activity of the finished products. Therefore, systematic identification is becoming essential in order to produce standardized finished herbal products. The present study includes two medicinal plant rhizomes; Alpinia calcarata Roscoe (Heenaratta) and A. galanga (Linn.) Willd (Aratta) whose microscopical build up was different from each other and was assessed by standard Pharmacognostical methods. Diagnostic identification characters of A. calcarata were compound starch grins, triangular-shaped starch grains, and plenty of simple starch grains in one parenchyma cell compared to that of A. galanga. Diamond-shaped silica crystals were found only on A. galanga rhizome powder. Present study has revealed an easy technique to identify two similar medicinal plant materials microscopically and this method can also be employed to detect the degree of adulteration in powdered raw medicinal plant materials as well.
