Ayurvedais a Hindu system of traditional medicine native to India and a form of alternative medicine. The earliest literature on Indian medical practice appeared during the Vedic period in India, i.e., in the mid-second millennium BCE. The Suśruta Saṃhitā and the Charaka Saṃhitā, encyclopedias of medicine compiled from various sources from the mid-first millennium BCE to about 500 CE, are among the foundational works of Ayurveda. Over the following centuries, ayurvedic practitioners developed a number of medicinal preparations and surgical procedures for the treatment of various ailments. Current practices derived (or reportedly derived) from Ayurvedic medicine are regarded as part of complementary and alternative medicine.

Ayurveda is a Sanskrit term, made up of the words "ayus" and "veda." "Ayus" means life and "Veda" means knowledge or science. The term "ayurveda" thus means 'the knowledge of life' or 'the science of life'. According to the ancient Ayurvedic scholar Charaka, "ayu" comprises the mind, body, senses and the soul.

Ayurveda can be defined as a system, which uses the inherent principles of nature, to help maintain health in a person by keeping the individual's body, mind and spirit in perfect equilibrium with nature.

Widely regarded as the oldest form of healthcare in the world, Ayurveda is an intricate medical system that originated in India thousands of years ago. The fundamentals of Ayurveda can be found in Hindu scriptures called the Vedas — the ancient Indian books of wisdom. The Rig Veda, which was written over 6,000 years ago, contains a series of prescriptions that can help humans overcome various ailments.

Ayurveda do to you

The aim of this system is to prevent illness, heal the sick and preserve life. This can be summed up as follows:

• To protect health and prolong life ("Swasthyas swasthya rakshanam")
• To eliminate diseases and dysfunctions of the body ("Aturasya vikar prashamanamcha")

Basic Principles of Ayurveda

Ayurveda is based on the premise that the universe is made up of five elements: air, fire, water, earth and ether. These elements are represented in humans by three "doshas", or energies: Vata, Pitta and Kapha. When any of the doshas accumulate in the body beyond the desirable limit, the body loses its balance. Every individual has a distinct balance, and our health and well-being depend on getting a right balance of the three doshas ("tridoshas"). Ayurveda suggests specific lifestyle and nutritional guidelines to help individuals reduce the excess dosha.

A healthy person, as defined in Sushrut Samhita, one of the primary works on Ayurveda, is "he whose doshas are in balance, appetite is good, all tissues of the body and all natural urges are functioning properly, and whose mind, body and spirit are cheerful..."

Tridosha - the Theory of Bio-energies

The three doshas, or bio-energies found in our body are:

• Vata pertains to air and ether elements. This energy is generally seen as the force, which directs nerve impulses, circulation, respiration, and elimination.
• Kapha pertains to water and earth elements. Kapha is responsible for growth and protection. The mucousal lining of the stomach, and the cerebral-spinal fluid that protects the brain and spinal column are examples of kapha.
• Pitta pertains to fire and water elements. This dosha governs metabolism, e.g., the transformation of foods into nutrients. Pitta is also responsible for metabolism in the organ and tissue systems.

Panchakarma - the Therapy of Purification

If toxins in the body are abundant, then a cleansing process known as panchakarma is recommended to purge these unwanted toxins. This fivefold purification therapy is a classical form of treatment in ayurveda. These specialized procedures consist of the following:

• Therapeutic vomiting or emesis (Vaman)
• Purgation (Virechan)
• Enema (Basti)
• Elimination of toxins through the nose (Nasya)
• Bloodletting or detoxification of the blood (Rakta moksha)
