CAM
Meaning of CAM: The label groups acupuncture with herbal remedies and meditation, practices sharing nothing except their position outside conventional care.
Definition of CAM
CAM stands for complementary and alternative medicine, a broad grouping of health practices used outside conventional medical care. Complementary means used alongside standard treatment; alternative means used instead of it. Those two carry very different consequences, and the combined abbreviation blurs a distinction that matters, which is why newer terminology has moved away from it.
What does it cover?
| Group | Examples |
|---|---|
| Natural products | Herbal preparations, vitamins and minerals taken beyond dietary need, probiotics |
| Mind and body practices | Meditation, yoga, tai chi, acupuncture, hypnosis, massage, breathing techniques |
| Manipulative practices | Chiropractic and osteopathic manipulation |
| Whole systems | Traditional Chinese medicine, Ayurveda, homeopathy, naturopathy |
The grouping is defined by what these practices are not, rather than by anything they share, which is why acupuncture and herbal medicine sit in the same bracket despite having nothing in common in mechanism, evidence base or risk.
Why has the terminology changed?
The phrase complementary and alternative medicine is being replaced by complementary and integrative health, and the United States research center in this field renamed itself accordingly. The reason is the alternative half. Practices used alongside conventional treatment and practices used to replace it raise entirely different questions, and lumping them together implied a coherence that does not exist. Integrative health also signals a narrower interest: practices with some evidence, used within mainstream care rather than in opposition to it.
How is the evidence assessed?
It varies enormously between practices and even between uses of the same practice. Some have been examined in randomized trials and show modest, specific effects; others rest on traditional use with little formal study; a few have been tested and found no better than placebo. Safety is a separate question from effectiveness, and natural does not mean inert. Herbal preparations can interact with prescribed drugs, altering how quickly the liver clears them, and supplements are regulated as foods in many countries, so their content and strength are not verified in the way a medication's are. That is the practical reason use is asked about during a medication history.

Good to know
The evidence supporting different CAM practices varies considerably, since some have been studied within formal clinical research while others rely mainly on traditional use, a distinction relevant when practices are being compared.
