Acknowledged as the oldest among the different streams of medicine in the world. Ayurveda has become a very popular with the tourists visiting Kerala in the recent years.
Ayurveda, literally meaning the science of life, is more than 3500 years old. Traditionally the knowledge of Ayurveda was passed on through the 'Gurukula' system ie. One master teaching a group of selected students. It was common to have the students residing in the master's house and working for the upkeep of the house. And whenever the master felt them fit to a practice medicine, he would let them start practicing on their own. Now the traditional knowledge has been improved through scientific research and is taught in various Ayurveda Colleges in Kerala. A graduate doctor in Ayurveda, takes 5 years of courses at college besides six months of internship and is considered on par with doctors of modern medicine.
Ayurveda is based on the vedic philosophy of healthy living as prescribed in the 'Atharvaveda', a vedic text on the Hindu philosophy. It is a system of preventive medicine which provides ideal lifestyles to prevent the onset of sickness and disease. The majority of Ayurvedic medicines are not mass produced, as Ayurveda treatment is based on the premise that every person has an individualized constitution and medicine have to be tailored to suit the individual. According to Ayurveda the human body comprises of 3 constituents known as the 'Tridoshas'. They are 'Vatha', 'Pitha' and 'Kapha'. Though these constituents vary from person to, one of the 'Tridoshas' predominates over the other two. This predominance can be identified by the physical and emotional characteristics of a person ('Personality types'). Accordingly two people suffering from the same ailment may be prescribed different medicine to suit their constitutions.
Yoga - The great Indian Road toGod
Yoga is the art of absolutism. It is the science for salvation. (Here salvation means life free from sins). The real word meaning of yoga is union of the god with man. In other sense the union of the cosmic power with human power.
Man is the miniature of the cosmos. He himself (she herself) is the temple of the soul. The soul is one and the only eternal phenomena. Realising the truth-is the first step to the true life. 
The eternal or the unchangeable force, which composed and played the unique rhythm of the universe, is the Athma or the Soul. This rhythm of the universe, which controls the human mind also. So we should learn and follow this God composed rhythm. If possible through yoga and Pranayama. 
Soul, mind and body have three separate identities. Yoga develops those identities to its maximum. As a result of dedicated and punctual practice those three identities came inunion with each other and become Charisma. 
Charisma may have so many word meanings. But here it means heavenly perfect personality, which helps to lead a rich life absolutely free from sins, wisdom, knowledge, morality and liberty are great gifts of the God through yoga. In short yoga is the great Indian road to God.
