What Is Sang Ji Sheng

There are about 35 species in this genus, and they are mainly distributed in southeastern and southern Asia. Among them, only a small number of species are distributed in eastern Africa. Some of these species have high medicinal value and are widely used in clinical applications.
Taxillus chinensis often grows in plains or low-mountain evergreen broad-leaved forests at an altitude of 20-400m. They are often parasitic on a variety of plants such as mulberry, peach, plum, longan, lychee, poplar, camellia oleifera, vernicia fordii, rubber tree, banian, bombax ceiba, pinus massoniana, or water pine. They are distributed in China, Thailand, Vietnam, Laos, the Philippines, Cambodia, and Malaysia.
From winter to the following spring, people gather the twigs of Taxillus chinensis, remove the thick stems and impurities, dry them, or steam them, then dry them, cut them into thick slices, and make them into herbal medicines.
