Dr. Rajan Sankaran, MD (Hom), is an internationally renowned thinker, teacher and writer of the homeopathic system of medicine from Mumbai (India). He graduated from the CMP Homeopathic Medical College in Mumbai where he was later associate professor for 25 years.

Dr. Sankaran is best known for his innovative concepts in homeopathy. His understanding of disease as a delusion—followed by his discovery of newer miasms, classification of diseased states into kingdoms (viz. plant, mineral and
animal) and the seven levels of experience—brought clarity into understanding diseased states.
