The basic principle of homeopathy is ‘like cures like’. In other words:
a substance taken in small amounts will cure the same symptoms it cause if it were taken in lare amounts. As the founder – dr. Samuel Hahnemann – put it: ‘Similia Similibus Curentur’.

Another main principle of homeopathy is the fact that it does not use pure material substance – as some substances could cause poisoning. Homeopathy prescribes only highly diluted dosage of a remedy, which is safe for humans and animals. Repeated experiments done by dr. S.Hahnemann, showed that diluting a substance in alcohol and water, makes the poisonous effects disappear completely. It also creates a greater potential to cure quickly, profoundly and gently. Even the most toxic plants can be used, but only on condition that every degree of dilution is accompanied by shaking a set amount of times. (succussion)

After numerous experiments and years of hard work dr. S.Hahnemann came to these conclusions, and these have been the basis for the development of homeopathy as it is known for more than 200 years. There have been all kinds of developments since then, but classical homeopathy means that the method is used as the founder of homeopathy, dr.Samuel Hahnemann, has meant it to be.
