Hey there — I’m Dr. Lin, a licensed TCM practitioner with 14 years of clinical work across China, Korea, Japan, and Vietnam. I’ve prescribed herbal formulas in Seoul clinics, co-taught pulse diagnosis workshops in Kyoto, and reviewed over 320+ regional herb substitution records from WHO-recognized TCM hospitals. So when people ask, *“Is TCM the same everywhere?”* — I laugh, then hand them this data-backed reality check.

Short answer? No. The core philosophy — Yin-Yang, Five Phases, Qi flow — stays rooted. But how it’s *applied*, *regulated*, and *taught*? Wildly different. Let’s cut through the myths.

First, regulation: China’s State Administration of TCM mandates standardized herbal processing (e.g., *Shu Di Huang* must be steamed with wine ≥9 hours), while Japan’s Kampo system only approves 148 formulas — all pre-packaged, patent-protected, and covered by national health insurance. Korea’s *Hanyak* allows more flexibility but requires dual licensing (Western + Oriental medicine) for prescribers.

Here’s what the numbers really say:

Country Approved TCM/Kampo/Hanyak Formulas Herb Standardization Rate Clinical Training Hours (Post-Grad) Public Insurance Coverage
China 1,285 (2023 Pharmacopoeia) 76% 1,500+ Partial (outpatient herbs: ~40%)
Japan 148 (Kampo) 99% (GMP-certified only) 800 (integrated MD track) Full (prescribed formulas only)
Korea 423 (2022 Korean Herbal Codex) 88% 2,000+ (dual-degree required) Yes (since 2013, 70% reimbursement)
Vietnam 211 (Y Học Cổ Truyền guidelines) 62% 1,200 (TCM + local herb training) Limited (pilot provinces only)
† Standardization rate = % of listed herbs with mandatory testing for heavy metals, pesticides, and species authenticity (per national pharmacopoeia).

Why does this matter to *you*? If you’re sourcing herbs, choosing a clinic, or building a wellness brand — these differences affect safety, efficacy, and even shelf life. For example: Japanese *Saiko-Keishi-To* uses *Bupleurum falcatum*, while Vietnamese versions often substitute locally grown *B. chinense* — same genus, 23% lower saikosaponin B2 content (per 2022 Hanoi University phytochemical assay).

Bottom line? Don’t assume ‘TCM’ is a monolith. Respect the roots — but always ask: *Where was it grown? Who processed it? Under which country’s standards?*
