A label saying “82 mg per serving, equivalent to approximately 567 mg of dry powders” looks like a contradiction. It is not. The two figures describe the same material at different stages of processing.
An extract is what remains after raw herb is processed to concentrate its active compounds and discard fibre and inert plant matter. So a smaller extract weight can represent a much larger quantity of the original plant.
A ratio like 7:1 means seven grams of raw herb produced one gram of extract. Multiply the extract weight by the ratio to get the raw-herb equivalent.
| Label says | Ratio | Raw-herb equivalent |
|---|---|---|
| 100 mg extract | 4:1 | 400 mg |
| 100 mg extract | 10:1 | 1,000 mg |
| 500 mg raw powder | 1:1 | 500 mg |
This is why comparing raw milligram figures across two labels tells you almost nothing on its own.
Some labels state a standardised percentage — for example “standardised to 5% withanolides”. That specifies the concentration of a marker compound, which is more informative than a ratio alone because it tells you about the active fraction rather than just the concentration factor.
A label giving both a ratio and a standardisation is being more transparent than one giving neither.
A proprietary blend prints one total figure covering several ingredients. It is legal, and it is occasionally defensible as formula protection. It also makes it impossible to know whether the expensive ingredient is present at a meaningful level or as a token dusting for the label.
As a rule of thumb: individually named amounts are a signal of confidence, and a single blend total is a signal to ask why.
