Homeopathy is a medical system based on holistic principles and beliefs that the body is designed to heal itself in the right environment. The human body is made up of organs, cells, neurons, and neurotransmitters that work together to maintain homeostasis (balance). Maintaining a constant internal environment (oxygen, vitamins, nutrients, and removal of waste) is necessary for optimal health and well- being. Laughter is good for the soul and a joyful heart is good medicine.
