There are no diet restrictions to be observed when one is under homeopathic medication. Diet restrictions are only to be followed for the particular ailment that one is suffering from and not for the treatment. E.g. if the patient is a diabetic, he should curtail his intake of excessive sugar or in a person with chronic renal failure, a low protein diet is advised etc. Camphorated food items are avoidable as camphor antidotes the effect of many homeopathic remedies.
