In detail
A 10:1 extract is made from ten kilograms of dried herb for every kilogram of finished extract. A 4:1 extract uses four kilograms. The ratio tells you how concentrated the soluble material is relative to the starting plant, but it says nothing about the marker content, the solvent, the plant part, or the carrier.
A poorly made 10:1 extract can contain fewer actives than a well-made 4:1 extract, especially if the finished powder is diluted with maltodextrin. Ratio extracts are useful for traditional formulas, teas, and food applications where the whole-herb profile matters; for a capsule with a label claim, a standardized extract is usually more useful.
Why it matters to a buyer
- Buyers often compare ratios as if they were strength; they are not.
- The ratio interacts with carrier and solvent, which affect dose and cost.
- A ratio without an identity test cannot confirm the plant or part.
What to ask a supplier
What is the exact herb-to-extract ratio, and is it verified or nominal?
Which solvent and carrier are used?
Can you provide a marker or identity result in addition to the ratio?
