The author, a homeopathic General Practitioner, through his experience in his surgery in a Paris suburb and in a low cost Health Centre in Paris draws up a picture of the situations in which his homeopathic expertise enabled him to respond to primary care through homeopathic therapy. He sets out the French social context, its possibilities and its impossibilities. He looks at the nosological and ethical limits of this therapy in the continuity of care. To illustrate his point, he presents six different subjects: a parturient, a new born baby, a young child, a teenager, a fifty year old man and a senior citizen.
