Diabetes mellitus is a persistent health problem that requires innovative strategies to improve health and needs a multifactorial approach for the treatment. Saptarangyadi Ghanavati, a formulated Ayurvedic compound consists of herbs with anti-diabetic potential.
To evaluate the hypoglycemic and antihyperglycemic activities of Saptarangydi Ghanavati.
Materials and Methods:
For hypoglycemic activity 18 Swiss albino mice were divided into three groups (6 in each). First group served as normal control, second group is the test drug and third is the standard control group. For antihyperglycemic activity 24 Swiss albino mice were divided into four groups (6 in each). First group served as water control, second negative control, third test drug and fourth as standard control group. Test drug Saptarangydi Ghanavati was suspended in water and administered to animals at the dose of 400 mg/kg. Glibenclamide was used as reference standard in both the models at the dose of 0.65 mg/kg.
Saptarangyadi Ghanavati showed mild reduction in Blood Sugar Level (BSL) at all the time intervals in normoglycemic mice; however, the observed decrease of BSL was found to be statistically non significant. In antihyperglycemic activity, even though the drug failed to cease the hyperglycemia in the first hour after the glucose overload, it attenuated the same in later hours in nonsignificant extent.
The study reveals that Saptarangydi Ghanavati has moderate hypoglycemic and antihyperglycemic effect.

In the present era, because of the life-style, the disorders such as hyperacidity and gastric ulcers are found very frequently. Satwa (starch) obtained from the rhizomes of two plants namely Curcuma angustifolia Roxb. and Maranta arundinacea Linn. are used in folklore practice for the treatment of above complaints under the name Tugaksheeree.
To compare the anti-ulcerogenic activity of the above two drugs in pyloric ligation induced gastric ulcer in albino rats.
Materials and Methods:
A total of 18 Wistar strain albino rats of both sexes grouped into three groups. Group C served as pyloric ligated control group, Group I received starch of C. angustifolia suspension and Group II received starch of M. arundinacea for seven days. On 8th day pylorus was ligated. After ligation the animals were deprived of food and water and sacrificed at the end of 14 h. The collected gastric contents were used for biochemical estimation and ulcer index was calculated from excised stomach.
Both the test drugs showed statistically significant decrease in the volume, increase in the pH, reduced the free acidity of gastric juice and decreased the peptic activity. The starch of C. angustifolia reduced a total acidity non-significantly while M. arundinacea reduced it significantly. Among the two drugs the M. arundinacea has effectively reduced the peptic activity, which is statistically significant. M. arundinacea shown statistically significant increase of total carbohydrates.
Both the test drugs proved anti-ulcer activity and prevents the chance of gastric ulcer. Among these two M. arundinacea is more effective.

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.

Over the centuries, herbs have served as a major source of medicines for prevention and treatment of diseases including diabetes mellitus. These herbs are getting more importance around the globe and many studies have provided safety and efficacy of such herbal drugs in different condition. Guduchi (Tinospora cordifolia [Willd.] Miers) is reported as highly potent Pramehahara (anti-diabetic) herb in Ayurveda and Guduchi Satva (GS) is popularly used to treat Paittika type of Prameha. In the present study, GS prepared from the stem of T. cordifolia was evaluated for hypoglycemic and anti-hyperglycemic activity in 18 h fasted mice. GS was suspended in distilled water and administered to animals at the dose of 130 mg/kg that showed the marginal reduction in blood sugar level (BSL) at all the time intervals in normoglycemic mice. In anti-hyperglycemic activity, administration of GS prior to glucose over load failed to attenuate BSL at all-time interval in comparison to glucose control group. The study concludes that mild hypoglycemic insignificant anti-hyperglycemic activities of GS.

Ipomoea sepiaria Koenig Ex. Roxb is considered to be one of the source plants of the classical herb Lakshmana. In folklore, the herb is well known for its laxative activity. This plant belongs to Convolvulaceae family. It is observed that the plants of this family especially the species of Ipomoea are rich in purgative resins. The present experimental study was carried out to evaluate the effect of leaf and root of I. sepiaria on intestinal transit time on Swiss albino mice and the test drugs were administered in dose of 400 mg/kg. Evaluation of intestinal transit time was carried out by adopting Kaolin expulsion test and latency of onset of kaolin expulsion in fecal matter. The results shows that both root and leaf samples of I. sepiaria have marked intestinal motility enhancing property, among which leaf sample is found to be better. Hence, for the therapeutic purpose leaf can be preferred to get better activity profile and also to prevent destructive harvesting of the plant.

Lepidium sativum Linn. (Chandrashura) of Family Cruciferae (Brassicaceae) is being used by the people of Gujarat for treating inflammatory condition like arthritis. To evaluate its anti-inflammatory activity, Charles Foster albino rats were selected and experiments were carried out in three groups, therapeutic dose group, twice of therapeutic dose group and control group. In Carrageenan-induced paw oedema, the test drug produced moderate anti-inflammatory activity; however, the effect did not show statistically significant activity due to variation in the data of the control group. In formaldehyde-induced paw oedema in rats, the test drug produced moderate to significant suppression. This indicates that Chandrashura has a strong inhibitory effect on proliferation of fibroblasts and also probably has connective tissue modulation effect.

The use of metals in traditional medicines is very often seen as matter of concern these days, especially the Bhasma preparations which are always under stringent observations for containing highly reactive inorganic elements such as lead, mercury, arsenic and others. One of the Bhasma extensively used in routine Ayurvedic practice is Tamra (copper) bhasma. If it is not prepared properly or Shodhana procedure is not done properly, it acts as a poison. To indicate its toxic potential, Ashtamahadoshas (eight major ill effects) have been quoted in classics and due emphasis have been given to its Shodhana procedure. In the present study, Tamra bhasma prepared from Shodhita and Ashodhita Tamra was subjected to oral toxicity study to ascertain the role of Shodhana process on safety profile of Tamra bhasma on subchronic administration to albino rats. Both the samples were administered to rats for 45 consecutive days at the doses of 5.5, 27.5, and 55 mg/kg. Animals were sacrificed on 46th day and parameters like hematological, serum biochemical, and histopathology of various organs were studied. Results showed that Tamra bhasma prepared from Ashodhita Tamra has pathological implications on different hematological, serum biochemical and cytoarchitecture of different organs even at therapeutic dose level (5.5 mg/kg). Whereas, Tamra bhasma prepared from Shodhita Tamra is safe even at five-fold to therapeutic equivalent doses (27.5 mg/kg). These observations emphasize the role of Shodhana and importance of dose in expression of toxicity of the medicinal preparations.

Lekhana Basti (medicated enema) is a Tikshna formulation which is basically aimed for Apatarpana of the body. The present study (medicated enema) was undertaken to evaluate its anti-hyperlipidemic activity in diet-induced hyperlipidemia animals. Parameters like changes in body weight, organ weight, serum total cholesterol, serum triglyceride, serum HDL cholesterol, and serum (LDL + VLDL) cholesterol were studied to assess the effect of therapy in comparison to the control groups. Lekhana Basti was found to be ineffective in producing anti-hyperlipidemic action potently, but still found to have cytoprotective activity against hyperlipidemia induced organ damage, which was also confirmed by attenuation of cell infiltration and microfatty changes on histopathological examination.

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.

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.

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 16th 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.

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.

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.

The present pharmacological investigation was undertaken to study the anti-pyretic activity of Guduchi ghrita formulations in albino rats against yeast induced pyrexia. Seven groups of six animals were used for the experiment. The yeast induced pyrexia method was standardized first by injecting 12.5% yeast suspension (s.c) followed by recording the rectal temperature at regular intervals. Then the evaluation of anti-pyretic activity of Guduchi ghrita formulations was carried out by using this standard procedure. Both the Guduchi ghrita samples including vehicle significantly attenuated the raise in temperature after three hours of yeast injection. After 6 and 9 hours of yeast injection also both the Guduchi ghrita samples attenuated the raise in temperature in a highly significant manner in comparison to both yeast control and vehicle control groups. The data generated during study shows that both the Guduchi ghrita formulations having significant anti-pyretic activity.

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.

Ashwagandharishta, an Ayurvedic classical formulation, is the remedy for Apasmara (epilepsy), Murchha (syncope), Unmada (psychosis), etc. Recent studies in animal models have shown that n-3 PUFAs can raise the threshold of epileptic seizures. The indigenous medicinal plant, called Atasi (Linum usitatissimum Linn.) in Ayurveda, or flax seed, is the best plant source of omega-3 fatty acids. The present study is designed to investigate whether Ashwagandharishta and Atasi taila (flax seed oil) protect against maximal electroshock (MES) seizures in albino rats. Further, a possible protective role of flax seed oil as an adjuvant to Ashwagandharishta in its anticonvulsant activity has also been evaluated in the study. MES seizures were induced for rats and seizure severity was assessed by the duration of hind limb extensor phase. Phenytoin was used as the standard antiepileptic drug for comparison. Both flax seed oil and Ashwagandharishta significantly decreased convulsion phase. Pre-treatment with flax seed oil exhibited significant anticonvulsant activity by decreasing the duration of tonic extensor phase. Contrary to the expectations, pre-treatment with flax seed oil as an adjuvant to Ashwagandharishta failed to decrease the tonic extensor phase; however, it significantly decreased the flexion phase (P < 0.001) and duration of the convulsions (P < 0.05). Both the drugs exhibited an excellent anti-post-ictal depression effect and complete protection against mortality.

The rhizome of Vacha (Acorus calamus) has been used in Ayurvedic medicine for the treatment of various ailments, such as epilepsy, headache, eye disorders, insomnia, loss of memory, etc. Previous studies demonstrated that Vacha rhizome is having significant anticonvulsant activity against various induced seizures models in experimental animals. Ayurvedic pharmacopoeia of India has advocated Shodhana (purificatory procedures) to be done prior to its use. In the present study a comparative anticonvulsant activity of raw and Shodhita (classically processed) Vacha rhizomes were screened against Maximal Electro Shock (MES) seizure model to assess the effect of classical purificatory procedure on pharmacological action of Vacha. Phenytoin was used as standard antiepileptic drug for comparison. Pretreatment with both raw and classically processed Vacha samples exhibited significant anticonvulsant activity by decreasing the duration of tonic extensor phase. Further classically processed Vacha statistically decreased the duration of convulsion and stupor phases of MES-induced seizures. The results obtained from the present study clearly confirmed the anticonvulsant activity of raw Vacha and subjecting to classical Shodhana procedure did not alter the efficacy of Vacha rhizomes instead it enhanced the activity profile of the Vacha.

The immunomodulatory activity of Shirishavaleha prepared from two different parts of Shirisha (Albizia lebbeck Benth), i.e., Twak (Bark) and Sara (Heartwood) as main ingredients was evaluated for humoral antibody formation and cell-mediated immunity in established experimental models. The study used Wistar rats of either sex weighing 200 ± 40 g, while the test drug was administered orally at a dose of 1.8 g/kg. Hemagglutination titer and body weight were recorded to assess effects on humoral immunity; immunological paw edema was assessed for cell-mediated immunity. Shirishavaleha prepared from heartwood shows significant enhancement in antibody formation, attenuation of body weight changes, and suppression of immunological paw edema, while Shirishavaleha prepared from bark shows weak immunomodulatory activity. The study therefore concludes that Shirishavaleha prepared from heartwood has significant immunomodulatory activity.

The present study was undertaken to evaluate the anxiolytic and anti-depressant activity of Sarasvata choorna. The anxiolytic activity was evaluated in elevated plus maze (EPM) and the anti-depressant activity was evaluated in forced swimming test (FST). The efficacy of Sarasvata choorna was compared with the standard anti-anxiety (diazepam 2 mg/kg) and anti-depressant (imipramine – 5 mg/kg) drugs. It was observed that Sarasvata choorna at the dose of 390 mg/kg is as effective as standard drugs used in anti-anxiety and anti-depressant activities in mice by increasing time spent in open arm and entries to open arm in EPM model and increasing immobility time in FST model respectively. Hence it can be concluded that Sarasvata choorna may be used as a potent therapeutic agent in treating anxiety and depressive disorders.

Basti therapy is used widely for treatment of various diseases in the field of Ayurveda with several proven clinical applications, however; the exact mechanism through which the benefits are obtained are yet to be ascertained in the light of the contemporary developments in clinical science. It is also not clear that when administered Basti the active principles in the formulation gain entry in to the systemic circulation or not. The present study was planned to acquire some preliminary data with regards to the absorption of phytochemical constituents of the formulations when administered in the form of Basti. Gallic acid was used as marker compound and it's absorption in systemic circulation was assessed using high performance liquid chromatography. Gallic acid present in Lekhana Basti (Emaciating/ Desiccating Medicated Enema) was found to get absorbed in to systemic circulation. Maximum concentration in serum was seen in the animal which received Lekhana Basti with Prakshepa Dravya ( Catalytic Adjuvant) in comparison to animal which received Lekhana Basti without Prakshepa Dravya. Area under curve in chromatogram was also more in animal which received Lekhana Basti with Prakshepa Dravya. From primary evidence created by HPLC study it can be said that, phytochemicals of the Basti formulation do get absorbed in systemic circulation.

In recent years, many Ayurvedic formulations are being researched to provide an effective antidepressant and anxiolytic drug in the field of psycho-pharmacology. The present study was planned to evaluate the anti-depressant and anxiolytic activity of Rasayana Ghana Tablet comprising three herbs Guduchi (Tinospora cordifolia Miers), Aamalaki (Emblica officinalis Garten) (RGT) and Gokshura (Tribulus terrestris Linn). Swiss albino mice were divided into four groups of six animals each, comprising of both male and female in each group. Group I received water served as normal control (WC), group II received vehicle and served as vehicle control (VC), group III received Rasayana Ghana tablet and group IV received standard drug diazepam (2 mg/kg) for anxiolytic study in elevated plus maze and standard antidepressant imipramine (5 mg/kg) for anti-depressant activity in behavior despair test. Rasayana Ghana tablet along with ghee and honey as vehicle is found to be having antidepressant and anxiolytic activity in experimental animals. Thus, this formulation can be used in prevention and treatment of depression and anxiety.

The purpose of the present study was to evaluate the diuretic activity of Veerataru [Dichrostachys cinerea (Linn.)] Kwatha in experimental animals by following the standard procedure. Randomly selected animals were divided into three groups of six animals each. The root of Veerataru was administered orally in the form of Kwatha at a dose of 5.4 and 10.8 ml/kg. Parameters like volume of urine, pH of urine and urinary electrolyte concentrations like sodium, potassium and chloride were studied. Veerataru Kwatha increased the urine output in a dose-dependent manner. However, it did not affect the urinary electrolyte concentrations. From the present study, it can be concluded that the root of Veerataru has diuretic property.

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.
