Traditional Chinese Uses

Shi Hu (dendrobium stem) is a cool, sweet herb that nourishes Stomach and Kidney Yin and generates Body Fluids. It is especially suited for thirst and dry mouth resulting from febrile illness depleting fluids or from chronic Yin deficiency. As a Kidney tonic, it brightens the eyes, strengthens the lower back and knees, and addresses bone-steaming deficiency heat. It is considered a precious herb of high clinical value and features prominently in anti-aging and restorative formulas.

Botanical Description

Fraxinus rhynchophylla (Chinese ash) is a deciduous tree in the Oleaceae family, growing 10-15 m tall with a broad rounded crown and grey-brown, longitudinally fissured bark on mature trunks; young branches are smooth and lenticellate. The opposite, pinnately compound leaves are 15-25 cm long with 5-7 broadly ovate to elliptic, sharply serrate leaflets, the terminal one largest, dark green above and paler beneath. The small, inconspicuous, apetalous, polygamous flowers appear in dense terminal panicles with the unfolding leaves in spring. The fruit is a slender, oblong-spatulate, single-winged samara 3-4 cm long containing one flattened seed. The medicinal Qin Pi is the dried bark of the trunk and branches, cut into curved strips or quill-like rolls with a yellow-brown outer surface (POWO; Wikipedia).
