Disease = Dis + Ease. It means not at ease and when a person do not feel himself mentally or physically at ease for a long term may be suffering from chronic disease.

Chronic diseases are slow and continue degeneration of health.

Every phenomenon in this universe is based on law of "Cause and Effect" Which says "If there is an effect there must be a cause always."

Homoeopathy treats chronic diseases according to Nature's law of cure , that is , cause must be treated and corrected to most possible limit and effect (i.e. disease ) , will be cured proportionally.

Where other modes of treatment try to suppress but do not remove the cause , which can be something like if you want to make surface smooth , in spite of removing a nail tries to hammer it repeatedly

Due to which chronic disease reappears again after a short relief. Homoeopathy believes in removing the root cause.
