like any other system of medicine, homeopathy also has it's own limitations.
1. A surgical problem which has progressed far beyond its initial stages might not respond to homoeopathy.
2. Some sudden life threatening situations like heart attacks,paralytic strokes,diabetic comas etc. might have to be initially treated with conventional medicine, till the patient is out of danger.
3 . It is relatively slow acting as compared to the steroids.
4. The success rate is not 100%.
