Introduction:. Acupuncture as an alternative method of pain treatment was created in China 3000 years ago. It still has many supporters. For years, it has been used in many countries to relieve labor pains, postoperative pains, pains caused by osteoarthritis, toothaches, and headaches. The World Health Organization (WHO) has significantly expanded the indications for the use of acupuncture. The aim: The primary aim of this article is to critically evaluate whether acupuncture is a scientifically validated therapeutic intervention or primarily a placebo effect? Material and methods: The material and methods section of this article involves a comprehensive review of existing literature, including systematic reviews, randomized controlled trials (RCTs), and meta-analyses on acupuncture. The review also includes observational data on patient outcomes, potential risks, and reported complications. Results: The effectiveness of acupuncture has been extensively studied, with varying levels of scientific support for different conditions. According to the National Institutes of Health (NIH), the strongest evidence supports acupuncture’s effectiveness in dental pain, postoperative nausea and vomiting, chemotherapy-induced nausea, and pregnancy-related nausea. Studies on lower back pain, headaches, and knee osteoarthritis have shown moderate benefits, leading some physicians to recommend acupuncture as a complementary therapy. Conclusions: An analysis of studies has shown the effectiveness of acupuncture in the treatment of nausea and headaches. The results also showed the benefits of using this method in relieving back pain. Acupuncture has been shown to be one option for pain relief, but it needs more research.
