Ingredient Profile & Common Uses
The commercial extract uses the dried ripe fruit of Vitex agnus-castus L., a member of the Lamiaceae family. This distinguishes it from raw chasteberry powder, leaf-derived materials, and extracts produced from other Vitex species. Full botanical identity and plant-part declaration are important because the shortened term “Vitex extract” can refer to chemically and commercially different ingredients.
Two specification systems serve different procurement objectives. Marker-standardized material provides a defined agnuside assay for analytical control, while 4:1, 5:1, and 10:1 extracts define concentration through the botanical-to-extract ratio. Ratio values describe raw-material input relative to finished extract and should not be interpreted as percentages of agnuside or another individual phytochemical.
The extract is used primarily in concentrated botanical supplements and multi-ingredient women’s wellness products. Its fine brown powder has an herbal, mildly bitter sensory profile and disperses in water rather than forming a completely clear solution. Haze or botanical sediment can therefore occur in aqueous formulations, while capsules, tablets, and dry blends generally present fewer dispersion challenges.
