Rasayana and Antioxidants
|by Dr. Sarika Rathod|
Rasayana karma is the speciality of the Ayurveda. It meant for healthy people in as much as they provide means for prevention and promotion of positive health. The term “Rasayan” denotes a specific meaning i.e. any type of drug, diet and regimens which promote longevity by preventing ageing and diseases.
Action of Vayasthapan dravyas:
Vayasthapan means a metabolic process especially anabolic and lead to youthful body complexion. It relates to modern preventive medicine through five process to maintain optimum health:
A free radical is simply defined as any species of independent existence that contain one or more unpaired electrons. An unpaired electron is one that alone in orbital. It can also be defined as “Molecules having unpaired electron in outer orbit and have ability to participate in the electron transfer reactions.” They are highly reactive in nature, thus also known as reactive oxygen species (ROS). Reactive oxygen species or oxidants are free radicals or electrons produced in the body due to increased oxidative stress.
Oxidative stress is caused by an imbalance between the production of reactive oxygen and a biological system's ability to readily detoxify the reactive intermediates or easily repair the resulting damage. In humans, oxidative stress is involved in many diseases, such as atherosclerosis, parkinson's disease, heart Failure, myocardial infarction, alzheimer's disease,
An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from substance to an oxidizing agent.
Oxidation reactions can produce free radicals, which start chain reaction that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid or polyphenols. Low levels of antioxidants, or inhibition of the antioxidant enzymes, cause oxidative stress and may damage or kill cells.
Relation between rasayan karma and anti oxidant activity:
Rasayan karma is a type of procedure or treatment in which special procedures are carried out and specific medicine is given for fixed duration with some restrictions.
Rasayan karma is followed by agni deepan and uttam dhatu nirmiti, oja nirmiti. Uttam dhatus are responsible for uttam quality of an oja production. Oja is the best part of the body constitution. An oja is of highest quality and quantity helps to increase immunity and decreases other health related problems thus enhancing the longevity and quality of life i.e. Sukhayu and Deerghayu.
Anti-oxidants are the responsible for the same in more or less manner. As they reduce the process of electron transfer that ultimately ends in healing process of the body caused by oxidation. Antioxidants can cancel out the cell-damaging effects of free radicals. These observations suggested that antioxidant might help prevent the conditions like atherosclerosis, parkinson's disease, heart failure, myocardial infarction, alzheimer's disease. There is evidence that oxidants might help prevent diseases such as macular degeneration, supressed immunity due to poor nutrition and neuro-degeneration.
