Homeopathy

Hmm, let me see;

aromatherapy, meditation and similar therapies are proven to reduce stress and help with mental health issues as has guided exercise which also helps with things like condition management and recovery times. Similar for deitetic support and counselling.

They aren't about curing illnesses but about making the passage of surgical and medical treatment easier, reducing recovery times and, with things like cancer, trying to optimise the odds of remission and recovery. They're proven and functional because we know what they do and why they help rather than things like homeopathy which demonstrably does nothing.

Oddly we're now making swift progress in useing non-medical therapies to support medical intervention in things like limiting the effects of dementia but failing to apply simliar principles elsewhere.
