Dr Sharma ,Basically Ayurveda is a science of life and more about preventive care.Still if infected,they can be cured by customized treatments according to the constitution of that person.Changes are also made in lifestyle and diet which acts as a support to the medication given.The root cause of the disease is removed rather than just symptomatic relief.
Ayurveda medicine is holistic or comprehensive of body, mind ans spirit; the conventional one is symptomatic rather than treating root cause. Ayurveda believes that body is "Dosh=Functional humors, Dhatu=Body tissues and Mala=Excretory matter" -"Doshdhatumalamulamhishariram".
Ayurveda medicine either herbal or mineral or herbo-metalic are the aggregation of many molecules acting on different targets in synergistic way. No doubts the action is slow takes much time, hence it is better and potent in chronic and life style related diseases. The Ayurveda medicine is safe and nature friendly.
More emphasis is given on prevention of diseases, during treatment also dietetic and activity=Karmabhyas is advised along with medical preparations.
The number of single, compound, marine, mineral, herbal, metalic drugs are more than one lac.
Biochemistry of Ayurved is fundamental based on PANCH-MAHABHUTA which has been accepted in very scientific way with the help of method of inferential analysis.
Tridosha ( three essential functional entities) and seven Dhatu (structural entities) are also analysed on the basis of its composition of Panchmahabhuta.
Similarly etiological factors i.e. diet, daily regimen, physical activities or psychological conditions are understood through correlation of their properties related with Panchmahabhuta.
Ayurved and all other Asian medicine systems works with its own theory of biochemistry.
