Valerian Root, Extract (valeriana Officinalis L.)

Valerian root extract (Valeriana officinalis L., CAS Number 8057-49-6) is a concentrated preparation derived from the dried roots and rhizomes of the valerian plant, a perennial flowering plant native to Europe and western Asia. The extract is obtained through solvent extraction processes that concentrate the plant's natural chemical constituents, including volatile oils and iridoid compounds. In the food industry, valerian extract is classified and used as a flavoring agent or flavoring adjuvant, contributing characteristic herbal, earthy, and slightly bitter sensory properties to food and beverage formulations.

Valerian root extract is utilized primarily in the beverage industry, particularly in herbal teas, botanical drinks, and some flavored beverages where authentic herbal flavor profiles are desired. It may also appear in limited quantities in certain food products, dietary supplements, and functional foods marketed for relaxation or wellness purposes. The extract allows manufacturers to achieve consistent flavor without adding whole plant material, which can affect texture and appearance. Typical use levels are relatively low, generally in the range of parts per million, reflecting the potency of the concentrated extract.

Valerian root has an extensive history of traditional use spanning centuries in European and Asian herbal medicine. According to FDA records, there are zero documented adverse events associated with valerian root extract as a food additive, and zero product recalls have been issued. The European Food Safety Authority (EFSA) has reviewed valerian preparations, and while affirming traditional use, notes that safety data in food applications remains limited. Individual sensitivity to valerian compounds exists in some populations, though serious toxicological effects are rare. The extract's safety profile in food applications appears favorable based on available evidence, though the absence of GRAS affirmation by the FDA indicates that comprehensive modern safety data packages have not been formally submitted or reviewed by the agency for this specific use.

Valerian root extract is not currently affirmed as Generally Recognized as Safe (GRAS) by the FDA for flavoring purposes, meaning it does not have formal FDA recognition for this specific food application. However, it is not prohibited or banned for use in foods in the United States. In the European Union, valerian preparations are permitted as traditional herbal medicinal products, though regulation of botanical extracts in food varies by member state. The extract may be used under the FDA's prior sanctioned substances framework or under the allowance for botanical ingredients with historical use, depending on application context. Manufacturers using valerian extract in food products bear responsibility for demonstrating safety and proper labeling.

Scientific literature on valerian root extract focuses primarily on pharmacological effects rather than food safety toxicology. Research published in peer-reviewed journals indicates that valerian contains compounds such as valerenic acid and valerenol, which have been studied for potential biological activity. Acute toxicity studies in animal models have not identified significant adverse effects at reasonable exposure levels. However, published food-specific safety studies examining valerian extract at levels used for flavoring are limited. Most regulatory conclusions rely on traditional use evidence, chemical composition data, and extrapolation from herbal medicine research. Additional formal toxicological testing specific to food additive use levels would strengthen the safety database for this ingredient.
