Introduction
Cornus officinalis (Asiatic Dogwood, shan zhu yu) has been used in Traditional Chinese Medicine for over 1,500 years for kidney and liver support, with particular emphasis on essence (jing) preservation and longevity. The dried fruit is one of the principal components in classical TCM longevity formulations including Liu Wei Di Huang Wan.
Industrial production proceeds by hot-water or hydroalcoholic extraction of dried Cornus officinalis fruit, followed by filtration, concentration, and spray-drying. Standardization to loganin (the principal iridoid glycoside marker) supports modern HPLC-based identity verification.
Recognized as a permitted food ingredient in China and other Asian markets; sold as a botanical dietary supplement in the U.S. and many other markets.
Strategic positioning combines established Traditional Chinese Medicine product applications (the volume market in China and Asia) with growing Western dietary supplement use in longevity and kidney-tonifying positioned formulations.
