Some wise words from my colleague Garreth who I had the pleasure of working with teaching on the Heartwood Professional program ๐ฟ
Why the "Gold Standard" Doesn't Work for Herbal Medicine.
The double-blind RCT is hailed as the gold standard of evidence. But that bar was built for pharmaceuticals, not plants. Trying to fit herbal medicine into that frame breaks what makes it work.
Research doses are almost never what herbalists actually prescribe. Extraction methods are wrong. Time frames don't match clinical reality. You can't blind someone to the taste and action of a real herb.
Isolating a single constituent makes sense for patenting. But whole plant St. John's Wort is remarkably safe. Isolate hyperforin and you have drug interactions. You've removed the buffering effect of the whole plant.
We have thousands of years of knowledge about how plants work, where they grow, how to extract them safely. That's not anecdotalโthat's data.
No research model can capture the complexity of a whole plant, individual variation, constituent synergy, or the clinical wisdom from daily practice.
When someone says herbal medicine isn't "evidence-based" because it hasn't passed a pharmaceutical trial, ask: evidence according to whose standard?
The evidence is in thousands of years of safe, effective use. It's in the clinical outcomes we see every day. It's in the fact that whole plant extracts work safely in ways isolated constituents often don't.
We don't need to apologize for that. We need to stop fitting our medicine into a box it was never meant for.
