Homeopathy, developed by Samuel Hahnemann in the late 18th century, was founded on the principle of ‘like cures like’ and used highly diluted substances to treat patients. While the foundation of homeopathy relied on experimental provings and not on numerical superstitions, anecdotal beliefs eventually attached themselves to the practice—largely through folk traditions and regional customs in Europe. The preference for odd numbers likely draws from older numerological and mystical beliefs, where odd numbers, especially three and seven, were thought to possess magical or spiritual significance. These numerical associations found a home in alternative healing communities, where empirical rules were often blended with symbolism. The specific odd-number belief is not a principle in Hahnemann’s original teachings, suggesting it evolved organically as homeopathy spread across cultures and regions.
