Homotoxicology (a modern form of Homeopathy), is the practice that studies the influence of toxic substances in the body, where symptoms and dis-ease are understood to develop from biological resistance to toxic substances (homotoxins).

This method of treatment utilises the body’s own healing processes in order to "cure" the illness, through simulation. Homotoxicology is based on the concept that ‘like cures like’, with substances being able to treat a condition as well as being able to cause. The remedies usually contain a dilution of the ailment being treated, which stimulates the condition and subsequently starts the self-healing response. The symptoms are purely there as part of the body’s tools to heal itself.
