Samuel Hahnemann was a German physicist who developed homeopathy, a method of natural medicine, in 1800s. According to him, the same substance that causes an unhealthy reaction in a human body can be used to cause a healthy reaction that can remedy the problem for someone struggling with similar symptoms. Simply put homeopathy is based on a simple principle of “like cures like.” While it may seem improbable, vaccinations in the western world of medication uses the same principle. However, it is less preferred to homeopathic medication due to its potential side effects and not to mention, painful needles. Homeopathy, on the other hand, is completely safe and side-effects free.
