Why alternative therapy or treatment?

1) Allopathy is a conventional treatment where doctor treats a disease not the Individuals.Alternative and holistic practitioners also treats the disease but technique is to treat  the individual by knowing the internal and external cause and symptoms.
2) Allopathy based on mechanical diagnosis like x-ray,ct scan,MRI etc.But alternative based on symptom,on multifactorial etiology-stress,bad air,food,water or due to bad parenting or society.
3) Allopathy is based on testing ,it may be wrong and due to diagnosis treatment may also be wrong.
4) Conventional Medicine has too much side effects as diarrhoea,fluid retention, blood diseases, damage of nervous system etc.

5) Again it is very costly and it also has some limitations. So Alternative healing treatments - Yoga,Pranayama, Meditation, Ayurveda, Homeopathy, Acupressure, Acupuncture are working very well in eastern countries without any side effects.People of western countries like United States used to consider these treatments outside the main stream or 'Alternative'But in last few decades, patient in western countries have become interested in these approaches and they have started to ask for them.Now some western medical school teaching non traditional therapies and some hospitals use them in their cures.
