In 1991, the International Herb Association established National Herb Week to be celebrated every year during the week prior to Mother's Day. The purpose of National Herb Week is to develop and coordinate national attention on herbs, herbal uses, herb businesses, and the IHA.

Every year since 1995, the International Herb Association has chosen an Herb of the Year to highlight. The Herb of the Year Program, spearheaded by IHA's Horticulture Committee, has established Herb of the Year selections up to 2015. All IHA members are invited to participate in the selection process. Long-standing member, Chuck Voigt, who has been involved in the selection process for many years explains, "The Horticultural Committee evaluates possible choices based on them being outstanding in at least two of the three major categories: medicinal, culinary, or decorative." Herb societies, groups, and organizations, from around the world, work together to educate the public about these important herbs throughout the year. The IHA publishes a booklet each year to celebrate that year's selected herb. IHA members contribute material ranging from growing information to botanical information to recipes. Members receive a single copy as part of their membership. Copies are available for purchase by members, businesses, and the general public.

Millions of individuals throughout the world use herbs in their day-to-day life. Members of the International Herb Association (IHA) are proud to support these individuals by providing quality products and services including information and education surrounding the use of herbs.
