Plant Parts
This plant, known scientifically as Rheum tanguticum, is valued primarily for its medicinal properties concentrated within its underground structures. The most significant part used in traditional medicine is the rhubarb roots, which are harvested for their therapeutic compounds. Specifically, practitioners focus on the thick, fleshy rootstock that develops beneath the surface. Within this structure, the root core serves as a vital storage area for essential nutrients and medicinal constituents. While the roots themselves are the primary site of interest, the plant's reproductive cycle also produces seeds, though these are typically not the focus of its medicinal application.- Total parts
