Thank you for your question.
Ultimately, I am a scientist and I use the scientific method, so I would approach this by looking at outcomes and offering to patients what we know about this approach and what we know about the indigenous approach. We may not know anything about an indigenous approach and we would explain it using our own scientific methods, but that doesn't mean it's without value.
Ultimately, it has to be the patient choosing what approach to use so that it's in line with their belief system, whether or not we can back it up with our western version of science.
