…step outside my head a minute…
Are you denying that there is a multibillion dollar industry who are raking in the money from unsuspecting consumers using unproven medical therapies?
If @kheredia truly has a circulation problem, which, based upon her description I doubt, then that means that she is having claudication from arterial obstruction. If she were to have arterial claudication and it were to go untreated, then not only would some bullshit herbal “remedy” like cinnamon NOT work, but it would be harmful and potentially limb threatening because she would eschew regular medical care.
Show me a placebo controlled double blinded randomized controlled trial that shows that cinnamon improves clinical outcomes in arterial claudication and I’ll change my tune. The only reason I didn’t suggest that kheredia seek immediate medical advice is that numbness is not a symptom of poor circulation.
Come to think of it, though, numbness can be a symptom of peripheral neuropathy of some kind. If she has a family history of diabetes then she should be tested for diabetes, not take cinnamon.
If she wants to put cinnamon in her coffee, by all means. Just don’t use it in place of proper medical advice.
