The latest issue (November, 2018) of Consumer Reports has a major article reviewing the efficacy and safety of a variety of "natural" cures as alternatives to traditional health care. Since according to a Consumer Reports survey of over 1000 adults 33% say that they have used alternative treatments in the past year, and more than half of these indicate that they prefer such approaches over mainstream or conventional medicine, this is an important topic for careful review.
So, what does "science" say about these treatments? What evidence is there that they work? Here is a summary of the Consumer Reports article. If interested, I encourage you to read the entire article (pages 34-43). And, keep in mind, since the FDA does not oversee supplements, there is no guarantee that you are getting what it says you are getting on the label.
Acupuncture: Some research shows that it works, especially for osteoarthritis, chronic headaches, and chronic back or neck pain. May even ease depression.
Apple Cider Vinegar: Little scientific evidence to support its health claims
Berries: Anthocyanin phytochemicals in berries act as anti-inflammatories and may provide other health benefits
CBD: Cannabidiol (from marijuana or hemp) health claims ahead of the evidence that it works
Chelation: Useful only for treating heavy metal poisoning and nothing else
Chiropractic: Can reduce lower back pain and help with headaches and neck pain
Cupping: Can be effective in short-term relief of chronic neck and lower back pain
Detoxes & Cleanses: Not needed and can be dangerous
Ear Candling: Ineffective and dangerous
Feverfew: May reduce the frequency of migraines in certain patients
Garcinia Cambogia: No evidence that it works and can be dangerous
Glucosamine & Chondroitin: Work no better than a placebo

There you have Consumer Reports’ take on alternative, “natural” medicines and treatments. I respect and generally trust Consumer Reports, but one thing I have learned since starting these blogs on healthy living is that there are thousands of studies out there, with varying degrees of scientific validity, using different subjects, testing different hypotheses, utilizing different interventions. Therefore, I know that you can probably find a study somewhere that does not agree with Consumer Reports’ conclusions. I only share this with you as one additional, reasonably reliable set of data points.
But I, for one, am drinking more tea.
