Any individual who can adapt easily to changing situation(physical, mental, microbial, chemical) can stay
healthy
ADAPTOGENS was first coined by Dr.NIKOLAI LAZAREV a Russian scientist only 50 years ago but Indian Physicians practicing before 5000years-RASAYANAS
It is sold in the market as Modern Nutraceuticals with different labels

An ADAPTOGEN is a substance that demonstrates a NONSPECIFIC
enhancement of the body’s ability to resist a stressor
NON SPECIFIC – NOT CAUSED BY SPECIFIC AGENT
RESISTANCE – THE POWER OF RESISTING
![Page 4: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/4.jpg)
PROPERTIES OF ADAPTOGENS:
•The substance is relatively Non – Toxic to the recipient•It has Non specific activity and increases resistance of organism to broad spectrum of adverse biological, chemical and physical factors•These substances tend to help, regulate or normalize organ and system function within the organism
![Page 5: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/5.jpg)
HOW DO THEY WORK ……….?
![Page 6: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/6.jpg)
One theory suggested that Adaptogens function primarily due to anti-oxidant and free radical scavenging activity
Most of the adpatogens are Anti-oxidants but substances having Anti-oxidant properties ( Green Tea, Rosemary, Cranberry) are not sufficient to make it an adaptogen.
Amphoteric is a substance that normalizes function of an organ or a system within the body
All the herbs are Amphoterics but none of them qualify as adaptogens.
So Adaptogens act as broad spectrum amphoterics to living organisms.
![Page 7: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/7.jpg)
Later research postulated that adaptogens work primarily by affecting Hypothalamic/Pituitary/ Adrenal (HPA) axis and Sympathoadrenal System (SAS)
Thus, adaptogens modulate our response to stress and help regulate the interconnected endocrine, immune and nervous system
This re-regulation of a highly disordered stress system is achieved by metabolic regulators such as cytokines, catecholamines, glucocorticoids, cortisol, serotonin, nitric oxide, sex hormones, corticotrophin releasing factor (CRF)
This broad array of biochemical activators explain why adaptogens have Anti- Inflammatory, Anti-Oxidant, Anxiolytic, Anti-Depressant or nervine effects as well
![Page 8: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/8.jpg)
Adaptogens can help people handle stress by providing :
•Anti- Oxidant activity•Liver protection and Anti toxin activity•Improved blood sugar metabolism•Less craving for alcohol and sugar•Improved immune resistance•Increased stamina and energy•Improved muscle tone•Increased strength•Faster recovery•Better focus and concentration•Less anxiety•Better sleep•Better motivation and productivity•A feeling of well being•Better moods

Stress induced health problems:
•Angina•Asthma•Auto immune Diseases•Cancer•Cardiovascular disease syndrome•Common cold•Depression•Diabetes( Adult onset type II )•Headaches•Hypertension•Immune suppression•Irritable Bowel Disease•Menstrual irregularities•Pre menstrual tension•Rheumatoid arthritis•Ulcerative colitis•Ulcers

The plants with Adaptogenic activity is
1. Red ginseng2. American ginseng3. Siberian ginseng4. Ashwagandha5. Astragalus6. Liquorice7. Tulsi8. Satavari9. Amla10.Ginger
![Page 11: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/11.jpg)
Ashwagandha Root ( Withania somnifera)
This herb is one of the most prominent Rasayana ( rejuvenative ) remedies of Ayurveda
It is one of the few calming Adaptogens and has traditionally been used for Anxiety, Bad Dreams, Insomnia and Nervous Exhaustion
It acts as Anti spasmodic and Anti Inflammatory, in treating Fibromyalgia, restless leg syndrome, mild Tourette’s Syndrome and Osteo arthritis
It is an immune amphoteric useful for hypo and hyper immune conditions
It enhances male fertility (sperm count and sperm motility)Due to its Iron content, it benefits iron deficient anemia
Ashwagandha also stimulates thyroid function

Amla : Shining through the Three Stages of Stress
It is one of the most used herbs in the world as it is a part of many formulas such as Triphala, consumed by millions daily with their meals as delicious and digestive condiment
![Page 13: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/13.jpg)
The general aim of the Adaptogen therapy lies in their ability to reduce stressful agitation reactions during the ALARAM PHASE of the stress response
Support the physiological rallying during the RESISTANCE PHASE of stress response
And prevent or at least delay the state of fatigue during the FINAL STAGE of the stress response
Doing so they provide a certain level of protection against long-term stress and eventual exhaustion and systemic decay
![Page 14: Evaluation of adaptogenic activity of the fruit extract](https://reader034.vdocument.in/reader034/viewer/2022052509/55d57854bb61eba92f8b45a7/html5/thumbnails/14.jpg)
Amla supports all the three stages of stress reactions and is shown in tests to be an Anti- Stress Immunomodulating Adaptogen that supports us in emotional and cognitive wellness
Amla provides a healthy balance between the aggressive factors of digestion ( the acids and enzymes) and the protective factors of digestion ( the mucous, structural cells and alkalinity)

CONCLUSIONS AND SUMMARY:Ashwagandha and Amla both are said to have Adaptogenic activity according to Ayurvedic medicines
The results show that even after exposure to stress conditions (UV light) for a considerable period of 15minutes the microorganism managed to survive
This was seen when a diluted sample of the organism in the presence of both the extracts after exposure to stress produced a good number of colonies
Though E.coli is said to be an organism that can resist heat, high temperatures and other forms of stress like exposure to UV light other organisms like S.aureus and Lactobacillus also showed excellent results

NOVELTY OF THE WORK:Normally we see that evaluation of adaptogenic activity of an herbal formulation or an extract is carried out by determining its effects on restrain stress (by immobilization of rats). The use of albino mice or albino wistar rat is commonly seen.
The novelty of the work is the use of microorganisms to evaluate the activity of adaptogens in the herbal extract.
Microorganisms of different strains are used to evaluate the anti-microbial activity of the Flavonoids present in the herbal formulations but a procedure to evaluate anti-stress activity of microorganisms in the presence of an adaptogen has never been performed
