Concept:
Homeopathy is based on the principle of similarity.
Step 1: The basic principle is similia similibus curentur.
Step 2: It means “like cures like”.
Step 3: A substance causing symptoms in a healthy person may be used in diluted form to treat similar symptoms.
Step 4: Balance of doshas is related to Ayurveda, not Homeopathy.
