What the ratio describes
An extract ratio describes a relationship between starting botanical material and extract under a stated definition. Ask whether the starting material is dry, whether the denominator is native extract or the commercial mixture, and whether carriers are included. Without these definitions a headline such as 10:1 is ambiguous and should not be used to rank two suppliers.
What an assay measures
A marker assay measures a defined constituent or group using a specified analytical method. The result depends on reference standards, sample preparation and reporting basis. A dry-basis result cannot be compared directly with an as-is result without moisture information. A high ratio does not establish a high marker content, and neither measurement alone establishes clinical benefit.
A fair comparison checklist
Request the ratio definition, extraction medium, carrier percentage if present, marker method and batch-specific result together. Check that the botanical species and plant part match. If these differ, record the materials as separate candidates and evaluate them against the same finished-product acceptance plan rather than converting the ratio into a presumed dose equivalence.
Comparison record
Keep the two candidate specifications side by side and highlight every unmatched definition before asking for a sample.
