Not Exactly but Treatment never depends on person, it depends on Disease.
Like If Someone gets Heart attack then only Allopathy can save him,
If someone has Pneumonia then He will die without Antibiotics.
But
If someone has malignant cancer then Allopathy only can prolong person's life but can't treat him completely where Aryuveda might treat him same way without side effects of Allopathy's medicines.
A..So In short if you have acute disease or emergency conditions then you don't have any option then Allopathy.
B..If you have Chronic disease which is life long and you can't treat them with Allopathy or Allopathy's side effects are so high then you can go for Aryuveda or Homeopathy.
