HCG stands for Human chorionic gonadotropin, a glycoprotein hormone produced during pregnancy that is also used as a weight loss supplement. HCG can either be injected in hormone form or ingested as a homoeopathic liquid product, with hcg weight loss drops often promoted as the safest way to use HCG for weight control. Homoeopathic HCG products were developed because of controversy surrounding the safety of injected HCG, as well as shortages of the substance being produced and an inability to meet demand. HCG weight loss drops use standard homoeopathic dilution methods to produce a homoeopathic product that is often sold for weight loss.

Homoeopathy is a form of alternative medicine that uses highly diluted preparations as a way to treat a variety of different conditions. Homoeopathy is a method of preparation, and can therefore be used in the treatment of a number of separate conditions. Within homoeopathy, the term remedy is used to describe the final preparations, which are made according to a particular procedure and intended to treat a wide range of conditions. HCG weight loss drops are a homoeopathic alternative to the HCG hormone, which is normally injected and can be difficult to obtain.

According to homoeopathic practitioners, homoeopathic remedies can be used to maintain the vital life force of an individual. In the philosophy of homoeopathy, the law of susceptibility says that a negative state of mind can attract hypothetical disease entities called miasms, which invade the body and produce a variety of different symptoms. Homoeopathy is often described as an holistic medicine, where diseases and sickness is seen as a disturbance to the vial life force. In the context of HCG weight loss drops, homoeopathic remedies are used to restore a natural sense of weight and form to the human body.
