This website offers Cancer patients information on traditional First Nation’s healing, including topics like the ceremonial use of tobacco and smudging. I found it particularly useful because the website goes to great paints to speak respectfully whilst still indicating that the use of traditional healing has not been scientifically studied.
I see this as an opportunity for researchers to examine the use of traditional healing methods that look at the whole human (medicine wheel) for treatment, instead of simply treating the body (chemo), and to examine biomarkers of disease or whole health outcomes (e.g. death rates) for those treated using traditional methods plus evidence-based western medicine. Many traditional healing methods have recently shown themselves successful in clinical trials (e.g. massage therapy & acupuncture), and I suspect that there are likely elements of traditional healing that will hold up to scientific rigor and help to support their use in broader populations.
