Which of the following is an example of a biologically based therapy?

• A. Acupuncture
• B. Massage therapy
• C. Herbal, vitamin and minerals, dietary supplements, special diets and foods
• D. Meditation

Answer: (A)

Biologically based therapies are interventions that change the body's biology through adjustable biological processes. Acupuncture fits this because stimulating specific points activates peripheral nerves, sending signals to the brain and spinal cord, which triggers the release of endogenous opioids and other neurochemicals. This biochemical cascade can alter pain signaling, immune response, and autonomic balance, showing a direct biological mechanism behind the therapy. The other options operate more through mechanical, mental, or lifestyle routes rather than directly engaging the body's biochemical pathways in the same way.
