Traditional Edict
King Fern / Elephant Fern (Paku Gajah / Guanyin Zuolian). Prehistoric giant fern with massive turnip-like lotus stipular rootstock. Supreme Sovereign for Postpartum Pelvic Floor Restoration (Raja Pulih Rahim): tones lax pelvic ligaments, pulls up uterine prolapse, cures pulmonary hemoptysis.
Cautions & Contraindications
- Distinguish from tree ferns (Angiopteris has turnip-like fleshy rootstock with ear-shaped stipules). Exceptional maternal and pediatric safety profile. SAFE and highly indicated in lactation.
Clinical Applications
- Postpartum pelvic floor muscle laxity and uterine prolapse (stimulating fascial collagen synthesis via Angiopteroside), pulmonary tuberculosis hemoptysis, closed bone fractures, and chronic asthmatic cough.
Quality Markers
Mechanism & Phytochemistry
1. Angiopteroside stimulates TGF-b1 in pelvic fibroblasts, surging Type-I/III collagen synthesis to restore uterosacral ligament tensile strength. 2. Phenolic glucosides cross-link proteins to halt bleeding.

THE SOVEREIGN PAKU GAJAH CONFINEMENT CONGEE (Bubur Ubi Paku Gajah): 30 to 50 g fresh (or 15 g dried) rootstock slices simmered with Astragalus (Huang Qi, 15 g), Shan Yao, and red dates in bone broth congee (consumed during confinement). Bone fracture poultice: fresh pounded stipules.
Appended Prescriptions
