The 200:1 Extraction Ratio Myth: A Scientific Examination of Tongkat Ali (Eurycoma longifolia) Standardization

The herbal supplement market frequently features Tongkat Ali products claiming ultra-high extraction ratios such as 100:1 or 200:1. But are these claims scientifically valid?

Laboratory testing reveals many "high ratio" products contain minimal to no active compounds—some are entirely different species. A must-read for practitioners and informed consumers.
