Since 1979
Forty-five years of the same formulas
Grandma's Herbs began in 1979 in St. George, Utah, when Master Herbalist Joseph VanSeters started making natural remedies from time-honored herbal knowledge — six formulas, on a kitchen counter.
Four decades later they're still made the same way, in the same place, by the same family. The tagline has never changed either: “Because They Work.”
“Because They Work.”
Every formula is made in the USA in GMP-certified facilities, with no fillers, additives, or artificial ingredients.

The Immune System: A Key to Wellness
Understanding the Immune System
The immune system is a complex network of cells, proteins, tissues, and organs that work together to protect the body. It functions as the body’s natural defense, identifying and responding to foreign substances, through a process called the immune response. Key players in this system include white blood cells, or leukocytes, which circulate through the body via lymphatic and blood vessels.*
