Rasayana, a Sanskritword (with literal meaning: Path (ayana) of the Juice (rasa), or Elixir vitae), is used to describe chemistry and alchemy, and chemistry is generally called Rasayan Shastra in Sanskrit, Marathi, Hindi, Kannada and several other Indian languages. Ancient rasayana texts center around the use of prepared forms of mercury (see samskaras), as do occidental alchemical texts. However, there is also ample mention of the preparation of medical tinctures in the ancient science of rasayana; rasayana is in fact a part of Ayurveda. |

| Ayurveda, the oldest health science has eight branches. Rasayana (rejuvenation) is one of th. Rasa has different meanings like "taste“, “essence", "flavor”, ”juice”, or “emotion", but is not limited to any of these. In therapeutic process Rasa is concerned with the conservation, transformation, and revitalization of energy. Rasa nourishes our body, boosts immunity and helps to keep the body and mind in best of health. Rasayana describes an herbal preparation that promotes a youthful state of physical and mental health and expands happiness. Rasayana herbs have high levels of both safety for daily use and effectiveness. They are given to small children as tonics, and are also taken by the middle-aged and elderly to increase longevity. |

Rasayana herbs and formulas are often confused with the categories of adaptogens, amphoterics, alteratives and tonics, although they are not identical. Rasayanas affect the body in a general way, i.e. they may affect the immune systemrather than the lungs. They are nontoxic in normal doses and are amphoteric, in that they won't over-tonify the body. Tonics will build up or stimulate the body towards normal health but can be over-tonifying. Alteratives will help normalize physiology, but do it through gentle eliminative functions that tend to focus on one or more organs, so are quite different. Amphoteric herbs seto have a built in buffer that will help the body achieve homeostatic or allostatic balance, building or eliminating to achieve physiological equilibrium. While all rasayanas are amphoteric, some amphoteric herbs can be specific to an organ and are thus not rasayanas. Both rasayanas and adaptogens are nontoxic, and amphoteric, but adaptogens tend to work on a body-wide basis, by stimulating the HPA axis and the neuroendocrine system. Some rasayanas do not stimulate the HPA axis or may focus somewhat more narrowly on major systems of the body such as the digestive or immune systems. However the categories tend to overlap and many herbs belong to both categories. |

Specific adaptogenic herbs are also included in rasayanas including amla, shilajit, ashwaganda, holy basil, guduchi and shatavari. |

The whole, aqueous, standardized extracts of selected plants (Tinospora cordifolia, Asparagus racemosus, Emblica officinalis, Withania somnifera, Piper longum and Terminalia chebula) were administered orally to experimental animals, in a dose extrapolated from the human dose, following which they were exposed to a variety of biological, physical and chemical stressors. These plants were found to offer protection against these stressors, as judged by using markers of stress responses and objective parameters for stress manifestations. Using a model of cisplatin induced alterations in gastrointestinal motility, the ability of these plants to exert a normalizing effect, irrespective of direction of pathological change was tested.... All the plant drugs were found to be safe in both acute and subacute toxicity studies. Studies on the mechanisms of action of the plants revealed that they all produced immunostimulation. The protection offered by Tinospora cordifolia against stress induced gastric mucosal damage was lost if macrophage activity was blocked. Emblica officinalis strengthened the defence mechanisms against free radical damage induced during stress. The effect of Emblica officinalis appeared to depend on the ability of target tissues to synthesize prostaglandins. Recent data obtained with Tinospora cordifolia suggest that it may induce genotypic adaptation, further opening the arena for more research and experimentation. |

Those classical Rasayana formulas, contained a large number of ingredients, including minerals, pearl, coral and gems, and included a specially processed (samskara) mercury (the word ras indicates mercury as an ingredient). Because of negative publicity and cost factor, the use of the classical rasayana formulas shown above has declined considerably, and most of the preparations available now have herbal ingredients with a couple of mineral and animal products. The non-availability and wild life protection act has made the use of musk, amber and parts of wild-life animals, nearly impossible. |
|
The current Rasayana formulas are based on such ingredients as amla (Emblica officinalis, which has very high stable Vitamin C), Terminalia belerica, Terminalia chebula, Shilajit (a mineral exudate high in fulvic acid), Long pepper, Black pepper, Ginger, processed Guggul, Guduchi, Ashwaganda, Shatavari and similar ingredients. |

Rasayana has meanings beyond healthful substances. Rasayana Shastra in Ancient India was much less developed than today. Nevertheless, the use and practice of Rasayana abounded in Ancient India, and some examples of applied rasayana include paints used in the caves of Ajanta and Ellora, Maharashtra state, the steel of Vishnustambha (literal meaning: the tower of Vishnu), and a processed wood sample in the Kondivade caves near the Rajmachi fort in Maharashtra. |
