Woman readingThis dictionary was developed by Thorne Vet with the average pet owner in mind. We want to help you communicate intelligently with your veterinarian on the medical issues and treatments for your pets. Just like talking to a doctor can sometimes be difficult for us all, often talking to a veterinarian is a confusing barrage of unfamiliar terminology. This dictionary was created to help take away the mystery of the terms used in animal medicine and make talking to your vet a simpler and less painful process for you.

A system of therapeutics founded by a German physician named Samuel Hahnemann (1755-1843). It is a philosophy of "like heals like". In this system, the treatments are composed of substances which, in their undiluted state, actually produce the symptoms of the disease in a healthy individual. The substances are diluted to infinitesimal amounts in solutions and vigorously shaken (succussed) before they are given to the patient. Many homeopaths also believe that an individual's mental, physical, and emotional constitution may also need to be treated. The potency is based on the dilution ratio and it is believed that the more diluted the dose, the more potent the effect. A dilution ratio written as 1x is 1 part substance to 9 parts dilution medium, 1c is 1 part substance to 99 parts medium, and 1m is 1 part substance to 999 parts medium. A remedy labeled 20c has first been mixed as 1 part substance to 99 parts dilution base. Then, 1 part of this mixture is then mixed with 99 parts of the base and this dilution process is continued for a total of 20 times.
