Starwest Botanicals started as a small retail herb shop in 1975 in Sacramento, California. They grew rapidly on the strength of their commitment to provide value through a combination of quality products, excellent customer service, and fair prices. In 1979, they built their first herb mill to have better control over the processing of their herbs. In 1980, they began importing herbs from several different countries and supplying manufacturers and wholesalers. They also began supporting the fledgling organic herb industry in 1980. In 1983, Starwest was named to Inc. magazines list of top 500 fastest-growing private companies.
Today, Starwest is one of the largest suppliers of organic herbs in the United States, with over 150,000 sq. ft. of modern warehouse and production space.
