Rhizoma Drynariae (Gu Sui Bu): A Bone-Healing Herb for Fractures, Lower Back Pain, and Kidney Yang
Introduction
Rhizoma Drynariae, known as Gu Sui Bu (骨碎补) in Traditional Chinese Medicine (TCM), is a powerful yang-tonifying herb traditionally used to mend bones, strengthen tendons, and support the Kidneys. Warm and slightly bitter, it is especially valued in treating fractures, lower back pain, and joint weakness. Its name literally means “mender of shattered bones,” highlighting its role in trauma recovery and skeletal support.
What Is Rhizoma Drynariae?
Gu Sui Bu is the rhizome of Drynaria fortunei, a type of epiphytic fern native to China. In TCM, it is classified as bitter and warm, entering the Kidney and Liver meridians. It is traditionally used to tonify Kidney yang, promote bone regeneration, heal fractures, and reduce hair loss due to Kidney deficiency. This herb is commonly found in both trauma and longevity formulas.
