See our full sample process →Milk Thistle Fluid Extract is a liquid ethanol extract drawn from the leaf of Silybum marianum, delivered as a full-spectrum, non-standardized preparation. Because it is an ethanol fluid extract, the finished liquid contains alcohol. Bio-Botanica manufactures it for R&D formulators and product developers who need a leaf-based milk thistle liquid with a Holistically Balanced constituent profile.
According to Cognitive Market Research, the milk thistle extracts market is projected to grow at a CAGR of roughly 6.00% from 2023 to 2030, and leaf-based liquids give supplement houses another entry point into that demand. Buyers exploring detox- and digestive-support concepts continue to ask for traditional botanical liquids they can dose in tinctures and shots.
This alcohol-containing liquid suits herbal tincture blends, liquid supplement concentrates, and functional shots where an ethanol carrier is acceptable. Brands can position it around traditional detox and digestive-support rituals for dietary supplement and functional beverage lines. It integrates readily into two-ounce dropper formats and multi-herb bitters.
