| Abstract|| |
Depression is a psychiatric condition in which there is loss of interest in all pleasurable outlets, viz. food, sex, work, friends, hobbies and entertainment. The prevalence rate of the disease is 6-8% in women and 3-5% in men. Ayurveda, the science of life, provides systematic management principles for depression. Mamsyadi Kwatha is one such formulation stated by Yadavji Trikamji Acharya in Siddha Yoga Sangraha and Bheshaja Samhita, which is said to be effective in psychiatric conditions. The ingredients are Jatamansi (Nardostachys jatamansi), Ashwagandha (Withania somnifera) and Parasika Yavani (Hyocymus niger) in an 8:4:1 ratio, respectively. The test drug was subjected for antidepressant activity in experimental models. The models selected for anti depressant activity were behavioral despair test, anti-reserpine test and Chronic Fatigue Syndrome (CFS) test in albino mice. The test formulation showed significant inhibition of behavioural despair (P < 0.05), weak to moderate anti-reserpine activity - ptosis (P < 0.001), catatonia (P < 0.01), sedation (P < 0.01) and moderate effect in CFS test (P < 0.050). These effects clearly show that Mamsyadi Kwatha has an anti-depressant activity.

| Introduction|| |
Ayurveda is the science of certainty and art of possibility. In Charaka Samhita it is stated that Ayurveda has no boundaries or limitations, it is not easy to acquire a comprehensive knowledge of the science of life. Therefore, one should put honest efforts to be in constant touch with this science. The wise considers the entire universe as their preceptor; it is only the unwise who consider it to be their enemy. One should therefore strive to obtain proper advice, which brings fame and which promotes longevity and nourishment that is acceptable to people.  It is mentioned that a disciple should always make efforts for the upliftment of his knowledge and adoption of such methods as would give him the good knowledge.
These words of Acharya Charaka depict the importance of a broad-spectra study. This experimental study is one among them. Although the Ayurvedic drugs have been in use since ages, it is essential to verify the efficacy of herbal drugs using the modern parameters. It is also helpful to elucidate the possible mode of action of the drug under trial in a particular clinical condition.
Depression is a condition characterized by altered mood. An estimated 3-5% of the world's population experiences depression on any given date. There is a loss of interest in all usually pleasurable outlets such as food, sex, work, friends, hobbies or entertainment. Diagnostic criteria include presence of depressed mood nearly every day, markedly diminished interest/pleasure in most or all activities and three or more of the following:
Community studies have shown that the prevalence rate of depression, defined by strict operational criteria, is approximately 6-8% for women and 3-5% for men. Depression is more common in lower social classes and among inner city dwellers. Women in their child bearing years are especially vulnerable. 
- Poor appetite/significant weight loss/increased weight gain
- Psychosomatic agitation/retardation
- Feeling of hopelessness
- Loss of energy or fatigue
- Feelings of worthlessness, self-approach or excessive or inappropriate guilt
- Complaints of or evidence of diminished ability to think/concentrate
- Recurrent thoughts of death, suicidal ideation, wish to be dead or attempted suicide. 
By seeing the above facts, it can be inferred that depression is the condition that needs more attention, appropriate management and prevention of recurrence. Ayurveda, the ancient treasure of health provides suitable management strategies, for this condition.
Mamsyadi Kwatha, an Ayurvedic formulation mentioned in Siddhayoga Sangraha of Yadavji Trikamji Acharya and Bheshaja Samhita is said to possess a very good effect in all psychological disorders. The components of Mamsyadi Kwatha are Jatamamsi (Nardostachys jatamansi DC.), Ashwagandha (Withania somnifera Linn.) and Parasika Yavani (Hyocymus niger Linn.) in an 8:4:1 ratio, respectively. It is a strong potent psycho neuro pharmacologically active compound and is subjected for antidepressant activity. , The current study attempts on evaluating anti-depressant activity of Mamsyadi Kwatha. In addition, anti-depressant activity of individual components of Mamsyadi Kwatha, viz. Jatamansi, Ashwagandha and Parasika Yavani is also attempted in the study.
| Materials and Methods|| |
Swiss albino mice (30 ± 10 g) of either sex were procured from the animal house attached to the institute, and they were housed in groups of six under standard laboratory conditions (temp. 23 ± 2°C, relative humidity 50-60%) with food (Amrut brand) and water ad libitum. All the experiments were performed only after the animals had acclimated to the laboratory conditions for at least 7 days and during morning hours (08.00-10.00 h). The experimental protocol was approved by the institutional animal ethics committee.
The raw materials [Table 1] were collected from the pharmacy attached to the institute and were subjected to pharmacognostical studies to authenticate them. The Kwatha of each drug and Mamsyadi Kwatha [Table 1] was prepared following the classical guidelines.  The Kwatha was prepared freshly each time just prior to administration to animals.
The classical dose of Kwatha is 80 ml/day.  Dose fixation for the experimental animals was done on the basis of body surface area ratio by referring to the standard table of Paget and Barnes (1964).  On this basis the mouse dose was found to be 8 ml/kg. The test drug was administered orally to overnight - fasted animals with the help of a gastric catheter sleeved to a syringe.
The selected animals were divided in to five groups and each group consisted of six animals.
Group - I (CG): Received distilled water as vehicle and served as the normal control group
Group - II (JKG): Received Jatamansi Kwatha in the dose of 8 ml/kg
Group - III (AG): Received Ashwagandha Kwatha in the dose of 8 ml/kg
Group - IV (PYG): Received Parasika Yavani Kwatha in the dose of 8 ml/kg
Group - V (MKG): Received Mamsyadi Kwatha in the dose of 8 ml/kg.
Behavioral despair test
Selected mice were divided in to five groups as mentioned above. This study was carried out after acute as well as chronic administration of test drugs. In the acute study, the test drug was administered only once whereas in the chronic study, the test drug was administered for 7 consecutive days. One hour after drug administration (in chronic study on 7 th day), the mice were forced to swim individually in a glass jar (25 cm × 12 cm × 25 cm) containing fresh water to a height of 15 cm and maintained at 25° ± 2°C. After an initial 2-min period of vigorous activity, each animal assumed a typical immobile posture. A mouse was considered to be immobile when it remained floating in the water without struggling, making only minimum movements of its limbs necessary to keep its head above water. The total duration of immobility was recorded during the next 4 min of a total 6 min test. The changes in immobility periods were studied after administering drugs in separate groups of animals. Each animal was used only once. 
Chronic fatigue syndrome
The employed procedure was similar to that of the "Behavioral despair test": This procedure was followed for 7 days. The drugs were administered according to grouping 1 h prior to the exposure to stimuli daily for 7 days. This chronic forced swimming produced depression and fatigue resembling chronic fatigue syndrome. 
An hour after the drug administration, reserpine (2.5 mg/kg) was injected to the mice. They were then observed for ptosis, sedation, and catatonia at 1 h, 2 h, 3 h and 4 h after the injection. Scores from 0 to 3 were given according to the intensity of the symptoms. Catatonia was measured by using wooden blocks and a wire stand apparatus. Sedation was measured by putting the mice in the center of three concentric circles drawn on a rubber sheet. The scoring was done according to the time that the mice took to move away (vide gross behavior test). Ptosis was measured by grading the closing of eyelids. 
Results from the pharmacological screening were expressed as mean ± SEM. Difference between the control and treatments in the experiments were tested for significance using the unpaired Student's "t" test. Values of P < 0.05 were considered as statistically significant.
| Results|| |
Acute treatment with Mamsyadi Kwatha failed to reduce the immobility duration of mice in comparison with the control group. However, on chronic administration, all the ingredients as well as Mamsyadi Kwatha significantly reduced the immobility duration in comparison with the control group; among them, the observed result in the Mamsyadi Kwatha - treated group was found to be better [Table 2].
An apparent and statistically non-significant reduction in immobility time was observed in the Mamsyadi Kwatha - treated mice subjected to CFS [Table 3]. However, when the 7 days average immobility time was calculated, the Ashwagandha and Mamsyadi Kwatha - treated groups showed significant decrease in immobility time in comparison with the control group [Table 4].
Data related to the effect of Mamsyadi Kwatha on catatonia, sedation, and ptosis scores in anti-reserpine test have been provided in [Table 5], [Table 6] and [Table 7]. Pre-treatment with Mamsyadi Kwatha significantly attenuated these parameters at the 1 st and 2 nd h of reserpine injection. However, at 3 h and 4 h Mamsyadi Kwatha failed to attenuate these parameters with the significant extent in comparison to control group.
| Discussion|| |
Behavioral despair test is the most frequently used experimental model to study antidepressant activity. The model is valid for a broad spectrum of anti-depressants, mainly including tricyclics and MAO inhibitors, which significantly decrease immobility time in FST.  Immobility is thought to reflect either a failure to persist in escape - directed behavior after persistent stress or the development of passive behavior that disengages the animal from active forms of coping with stressful stimuli.  In the present study on acute single dose administration, only Jatamansi produced significant anti-depressant activity. However, on chronic administration all the three ingredients and the test formulation produced significant inhibition of behavioural despair in mice. The observed effect may be attributed to blockage of 5-HT reuptake or MAO inhibition.
The CFS - has a multifunctional etiology. It is due to abnormality of the hypothalamic - pituitary adrenal axis and mild hypo-cortisolism of central origin. Decrease in plasma levels of 3-methoxy-4 hydroxy phenyl glycol, one of the catecholamine metabolites and significant increase in basal plasma levels of serotonin metabolites, 5-hydroxy indole acetic acid - are the other abnormalities observed. 
Reserpine-induced ptosis, catatonia, and sedation are due to depletion of noradrenaline, dopamine and 5-hydroxy tryptamine content in concentrated neurons.  It can be suggested that the test drugs possess a weak antagonizing effect against this mechanism. Being a poly herbal formulation with proven anti-depressant and other CNS activities of Jatamansi, , Ashwagandha, , and Parasika Yavani may attribute role multiple active principles in observed activity profile.
| Conclusion|| |
From the above observations, it can be concluded that Mamsyadi Kwatha possesses anti-depressant activity. Being a poly herbal formulation, the observed activity profile may be attributed to one or more bioactive principles present in the components of this formulation. However further studies are required to determine the exact mechanism.
