Understanding concentration ratios
Zhenatura focuses on real herbal potency, not just numbers.
Why concentration ratios don’t tell the whole story
Interpreting the concentration ratio of concentrated herbal powders is a complex topic often subject to varying industry definitions. While a common standard exists, it frequently oversimplifies the scientific reality of herbal extraction.
The calculation variable
Generally, concentrated powders are produced by decocting raw herbs, followed by atomization (spray drying) where the medicinal liquid adheres to excipients to form granules. Manufacturers often calculate concentration ratios based purely on input-to-output weight.
For example, in some manufacturing models, if 100kg of raw Peppermint (Bo He) yields roughly 6kg of pure extract, a manufacturer might add excipients to create 10kg of finished powder. Because 100kg of raw material resulted in 10kg of finished product, this is often marketed as a “10:1” concentration. Many manufacturers use this straightforward input-output calculation to claim high concentration ratios.
The biological reality
However, a fixed numerical ratio does not account for the biological variance between plant parts. Extraction yields vary significantly by botanical structure:
● Leaves: Typically yield 5–9% extraction rates.
● Flowers: Typically yield around 5%.
● Roots/Rhizomes: Yields are often higher, ranging from 15–25%.
● Saccharide-rich herbs: Yields increase further due to natural sugar content.
Furthermore, the yield is directly influenced by the quality of the raw starting material. Therefore, a concentration ratio should not be viewed merely as a mathematical relationship between raw input and finished weight; it is a dynamic value affected by multiple biological and processing factors.
Single herbs vs. classical formulas
At Zhenatura, we believe it is essential to focus on the retention of active Quality ingredients and therapeutic Quality potency, rather than relying solely on a simplified numerical concentration ratio.
While single herb ratios vary, classical formulas present even greater complexity. A formula is a synergy of multiple ingredients, each with unique extraction characteristics. Applying a simple linear calculation to these complex mixtures is scientifically inaccurate.
Quality by design
Our manufacturing partner brings over 80 years of pharmaceutical history to this process. Rather than simply testing quality after production, we employ a “Quality by Design” philosophy. This rigorous approach ensures that therapeutic efficiency is prioritized over marketing numbers. By controlling quality through advanced analysis and design, we guarantee that every Zhenatura single herb and formula delivers the pronounced therapeutic results practitioners and patients expect.
Our approach
Pre-production: Designing processes to ensure excellence before
manufacturing begins.
In-process Control: Using Process Analytical Technology (PAT) to monitor pharmaceutical unit operations for each specific herb.
Continuous Verification: Ongoing process validation to meet strict global distribution requirements.
