Western herbs lack this systematic approach and careful analysis of interactions.
"Please note that you should never self-prescribe TCM ingredients. A TCM ingredient is almost never eaten on its own but as part of a formula containing several ingredients that act together. Please consult a professional TCM practitioner, they will be best able to guide you."
Yes. But it depends. When I started to supplement comprehensively, I searched for an experienced practitioner. Turned out not that easy.
Therefore, I monitored systematic interactions of lifestyle changes and supplements by regular lab-testing myself instead. It did work out for me that way.
2 very experienced and old practitioners I was recommended: An Orthomolecular and an Ayurvedic (which often use the same herbs as TCM). Both concluded at the end of their first very long consultations: with the severity of my diseases, they would do it as I did already anyway in their field of expertise (Getting hold of as many different nutrients and herbs, for expeimentally exploring their synergistic effects)-
I for example, do take many Eastern herbs (like Bittergourd), which aren't recommended to you by your practitioner. Also, numerous herbal combinations. Lab testing didn't show negative effects in my case, but improbable remissions instead.
Overall, much of those, like Bittergourd or Drumstick, one even gets with regular local meals in Asia. Dietary items, with no need of a prescription, as for chemicals. Of course, it is much better to have a knowledgeable TCM or Ayurvedic practitioner for that. Also saves one having to learn about those herbs.
But if one doesn't find, herbs or supplements aren't automatically off-limits. If one researches those sufficiently enough, takes responsibility for possible missteps, and monitors physiologic effects, they are many times' saver than the prescription Polypharmcy practiced by licensed MDs in the west against chronic diseases.
As usual:
I made the experience that it is always more efficient and safe to start with the lowest possible dose of a new supplement, then increase gradually over months and years. And better start with one agent at a time.
While doing actual lab-tests to see critical nutrients stay in range, ie. serum 25(OH)D, ferritin, retinol and retinol binding protein, copper, selenium, electrolytes, .. additional to regular tests like CBC, kidney and liver functions, hormones, etc.
Much saver than licensed Polypharmacy. Where most MDs don't even mention the difference between normal or optimal lab reverence ranges.
