Ayurveda (the science of art of healthy living) is one of the branches of Vedas. It is regarded as upaveda (offshoot) of Atharva-veda. It is a stream of the knowledge passed on from generation to generation from teachers to their students and so on. This knowledge is in a continuous flow. From where it came is not sure, who started this chain, none can tell about it. Beside teachers and students, it is passing on from a father to his son and from a mother to her daughter. It is flowing since eternity parallel to the Vedic literature that is why its emergence has been said to be from the creator (Brahma) himself. It is called eternal because nobody knows when it was not there. All this shows its long tradition and deep attachment to the Indian culture.
Etymologically Ayurveda has two word- Ayu and Veda. Ayu means life and Veda stands for the knowledge. So strictly speaking Ayurveda is knowledge for life. For what this knowledge is? What is the aim of Ayurveda? Talking about both Paramount Scholars of Ayurveda- Charka and Sushruta has told that- Aim of Ayurveda is to prevent the diseases in a healthy person and to cure the diseased one. They have given these following definitions of Ayurveda
Health can’t be bought we know it very well but only few of us understands it. If one wants to remain healthy, drugs can’t do this. Drugs are for diseased ones. Conventional medicines are aimed to eliminate the diseases from the body, not to maintain the health of a healthy fellow. On other hand Ayurveda has open opinions about health, where Ayurveda says that health should be maintained; on other hand Ayurveda promotes the preventive aspect also. So Ayurveda is not for those only who are suffering with diseases due to mistakes made by them in their food habits and lifestyles.
Ayurveda is blessed with the following thoughts, making this an all time useful knowledge An individual is treated with specific considerations about him according to his metabolic, genetic, in-vivo specialization; known as Prakruti in Ayurveda. Herbs are used according to the need.
Food is a medicine here, as foods are capable to change the inner atmosphere of the body. As all these matters are capable to collect cosmic energies, while these grow up. Rasyanas are meant to control and delay unexpected aging process and to give strength to the immune system of individual organs and body systems. Use of home-remedies help to maintain the health without using synthesized chemicals, which are hazardous to the health and internal system of the body. Naturally blessed herbs are meant to provide the complete nourishment to all tissues and every cell. Near to nature, so makes our body system natural.
Ayurveda medicine, is a system of medicine with historical roots in the Indian subcontinent. Globalized and modernized practices derived from Ayurveda traditions are a type of complementary or alternative medicine. In the Western world, Ayurveda therapies and practices (which are manifold) have been integrated in general wellness applications and as well in some cases in medical use.
The main classical Ayurveda treatises begin with legendary accounts of the transmission of medical knowledge from the Gods to sages, and thence to human physicians. Thus, the Sushruta Samhita narrates how Dhanvantari, "greatest of the mighty celestial," incarnated himself as Divodāsa, a mythical king of Varanasi, who then taught medicine to a group of wise physicians, including Sushruta himself. Ayurveda therapies have varied and evolved over more than two millennia. Therapies are typically based on complex herbal compounds, while treatises introduced mineral and metal substances (perhaps under the influence of early Indian alchemy or rasaśāstra). Ancient Ayurveda treatises also taught surgical techniques, including rhinoplasty, perineal lithotomy, the suturing of wounds, and the extraction of foreign objects
Although laboratory experiments suggest it is possible that some substances in Ayurveda might be developed into effective treatments, there is no evidence that any are effective as currently proffered.Ayurveda medicine is considered pseudoscientific. Other researchers consider it a protoscience, or trans-science system instead. Close to 21% of Ayurveda U.S. and Indian-manufactured patent medicines sold through the Internet were found to contain toxic levels of heavy metals, specifically lead, mercury, and arsenic. The public health implications of such metallic contaminants in India are unknown.
Some scholars assert that Ayurveda originated in prehistoric times, and that some of the concepts of Ayurveda have existed from the time of the Indus Valley Civilization or even earlier.Ayurveda developed significantly during the Vedic period and later some of the non-Vedic systems such as Buddhism and Jainism also developed medical concepts and practices that appear in the classical Ayurveda treatises. Humoral balance is emphasized, and the suppressing of natural urges is considered unhealthy and claimed to lead to illness. Ayurveda names three elemental substances, the doshas (called Vata, Pitta and Kapha), and states that a balance of the doshas results in health, while imbalance results in disease. Ayurveda has eight canonical components, which are derived from classical Sanskrit literature. Some of the oldest known Ayurvedic texts include the Suśrutha Saṃhitā and Charaka Saṃhitā, which are written in Sanskrit. Ayurveda practitioners had developed various medicinal preparations and surgical procedures by the medieval period.
