Ayurvedic healing is based on the principle of Tridosha that is Vata (air), water (kapha) and pitta (fire). Ayurvedic therapies and medicines are mostly derived from plants, and a few from minerals and animal kingdom. Diseases are also treated based on the influence of the biochemical activity of flavours and the cooling and heating energies on the Tridoshas.
Ayurvdic system of healing classifies diseases as belonging to seven categories, Genetic, congenital, constitutional, traumatic, seasonal, infectious and natural. Diseases caused due to genetics, include diabetes, blood pressure, tuberculosis, asthma and hemorrhoids which could be inherited from parents/ancestors.
Diseases caused due to the nutritional defects of the mother during pregnancy (when the Vata dosha becomes imbalanced) could lead to congenital diseases, like blindness, dwarfism while the imbalance of Pita could lead to alopecia, and imbalance of kapha might lead to albinism.
Constitutional diseases may be caused due to imbalance of the three doshas that could lead to behavioural problems and disturbance in the diet. Constitutional diseases can be of two kinds, manasika (psychic) or Sharirika (physical).
Traumatic diseases may be due to an external or an internal trauma. Diseases caused due to external injuries like bites of animals, or accidents, or sharp instruments are external trauma, while over-strain and stress could lead to internal trauma.
Seasonal diseases are due to imbalances caused in the body through changes in the climatic conditions. When the body fails to adapt itself to the sudden changes in the weather, it could lead to seasonal diseases.
Infectious diseases could be the diseases arising due to natural calamities like flood, earth quake, lightening etc. It is also considered as diseases that are water-borne, air-borne and could spread from one individual to the other. This is caused by organic or natural changes in the body. It could be related to hunger, sleep or thirst or due to natural ageing process.
Ayurvedic healing is done only by assessing all these symptoms, their root cause and nature of the diseases.
