No, homeopathy does not attempt to replace conventional medicine.
The whole philosophy of homeopathy is that it is a complementary medicine. Therefore, it complements both conventional medicine and patient lifestyle.
Homeopathy offers people the opportunity to self treat relatively minor ailments without using allopathic (conventional) medicine. They can be safely used alone or in conjunction with conventional medicine.
Homeopathic remedies offer treatments for a wide range of ailments, however, there are many areas where it may be more suitable to use a conventional medicine, particularly when treating serious medical conditions.
If in doubt, patients are advised to contact their doctor or homeopath regarding their own medical circumstances.
