Traditional Edict
Orange Bishop / Curved-Bracted Costus (Pacing Jingga / Cheng Bao Bi Qiao Jiang / Wan Bao Bi Qiao Jiang). Flaming scarlet-orange cone bracts with recurved tips. Sovereign for Burning Cystitis & Joint Swelling: boiled rhizome tea unblocks urinary strangury, flushes uropathogens, and drains arthritic joint effusion.
Cautions & Contraindications
- Features diagnostic bright orange bracts with outward-curving (recurved) tips. High clinical, urological, and joint safety profile. Safe during lactation; moderate doses in pregnancy.
Clinical Applications
- Acute cystitis, urethritis, and burning dysuria (uropathogenic E. coli anti-adhesion and ureteral relaxation via Costunolide >= 0.50%), nephritic dropsy and fluid retention, and rheumatoid/osteoarthritic joint inflammation.
Quality Markers
Mechanism & Phytochemistry
1. Diosgenin downregulates synovial NF-kB, TNF-a, and COX-2 (IC50=2.4 uM), easing joint stiffness. 2. Costunolide exerts membrane-lytic action against Gram-negative uropathogens.

THE ORANGE BISHOP UROLOGICAL FLUSH TISANE: 15 to 20 g dried sliced rhizomes boiled with Misai Kucing (15 g) and Che Qian Cao (10 g) in 600 mL water for 20 min; drink warm twice daily (clears urinary burning in 24-48h). Rheumatic joint decoction: 15 g rhizome slices boiled with Taxillus.
Appended Prescriptions
