Kills parasites, dispels Dampness and stops itching
Traditional Chinese Uses
Tu Jing Pi is the root or trunk bark of the golden larch (Pseudolarix amabilis, Pinaceae; Cortex Pseudolaricis), a pungent, warm herb of the external-application category acting on the Lung and Spleen channels. It kills parasites, dispels Dampness, and stops itching, and is used almost exclusively as a topical remedy for fungal and parasitic skin disease: tinea (ringworm) of the body, scalp, and feet, tinea cruris and genital itching, scabies, and damp, itchy eczema. It shows fungicidal activity against the dermatophytes that cause ringworm.
It is applied as a wine or vinegar-based tincture, or ground to powder and mixed with vinegar, and painted on affected areas. The bark is slightly toxic and is intended for external use; internal use is avoided except under close professional supervision.

Botanical Description
Tu Jing Pi is the root bark of Pseudolarix amabilis, the golden larch, a deciduous coniferous tree of the family Pinaceae endemic to mountainous regions of eastern China. Mature trees reach 20 to 40 metres in height with a broad, conical to spreading crown and reddish-brown, fissured bark. The needle-like leaves, 3 to 6 centimetres long and soft to the touch, are borne in two ways: spirally on long shoots and in characteristic rosette-like whorls of fifteen to thirty on short, knobby spur shoots. The foliage turns brilliant golden-yellow in autumn before falling, accounting for the common name. Erect, ovoid cones 4 to 7 centimetres long disintegrate at maturity to release winged seeds. The bark stripped from the roots and lower trunk is yellow-brown externally and yields the medicinal material.
