Fortune's Drynaria
Drynaria fortunei
In traditional Chinese medicine, this shaggy-rooted fern earned the name Gu Sui Bu, which translates roughly to mender of broken bones, a reputation that grew from centuries of use in supporting fracture recovery and easing the deep, aching pain of injured joints. Practitioners traditionally turned to its rhizome as a kidney tonic as well, the kind of herb reached for when someone's hearing had grown faint with age, their teeth had loosened, or their lower back complained on cold mornings. It found its way into liniments for sprains and bruises long before modern medicine had a name for inflammation, valued simply because it seemed to help old injuries knit and settle. Today it remains one of the more distinctive rhizome herbs in the traditional pharmacy, prized as much for its story as its shape.

Traditional preparations.
The classic preparation, simmered rather than steeped, since a tough woody rhizome needs more coaxing than a leaf or flower to give up what it holds.
Traditionally, 6 to 9 grams of the dried sliced rhizome are simmered in 500 ml of water for 20 to 30 minutes, then strained and sipped warm.
A gentler, everyday version for those who want a milder cup rather than a full decoction.
Traditionally, a small handful (about 3 to 5 grams) of dried rhizome slices is simmered gently in 250 ml of water for 10 minutes, then strained before drinking.
Safety.
Avoid during pregnancy and while nursing. Use caution alongside blood thinners or medications for bone or kidney conditions, and don't use it in place of medical care for an actual fracture.
