Glabrous Greenbrier Rhizome … Safety & Interactions
Tu Fu Ling · Rhizoma Smilacis Glabrae
Contraindications
- Marked deficiency-cold without dampness, toxicity, or joint obstruction
- Use as an assumed substitute for Ba Qia or other Smilax rhizomes without authentication
Cautions
- Species confusion is common in Smilax trade material, so authenticated Tu Fu Ling should not be assumed interchangeable with Ba Qia or unrelated sarsaparilla products.
- Memorial Sloan Kettering notes preclinical findings suggesting possible CYP2D6 and CYP3A4 effects, so concentrated extract use deserves caution with narrow-therapeutic-index medicines.
- Human clinical evidence remains limited; most modern literature is preclinical and should not be overextended into stand-alone treatment claims.
