Complementary and Alternative Therapies and Supplements
This article introduces common complementary and alternative therapies and supplements considered by cancer patients, including acupuncture, resveratrol, aromatherapy, CoQ10, Gerson therapy, and high-dose vitamin C. It outlines their scientific basis and limitations, helping patients make informed choices during treatment.

Many cancer patients explore complementary and alternative medicine (CAM) or supplements during treatment. However, not all methods are supported by strong scientific evidence, and some may even interfere with standard treatments. Below is a summary of commonly discussed approaches and their current research findings.
1. Acupuncture
- Evidence: Multiple studies show acupuncture can help reduce chemotherapy-induced nausea and vomiting.
- Status: Considered one of the better-supported complementary therapies.
2. Resveratrol
- Source: Found in grape skins, peanuts, and pine bark.
- Evidence: Animal studies suggest potential anti-cancer properties, but human trials lack sufficient evidence. Effective doses in humans remain unclear.
3. Aromatherapy (Essential Oils)
- Use: Inhalation or diluted topical application.
- Evidence: May reduce anxiety and stress in the short term.
- Limitation: No approval from the U.S. FDA for cancer treatment.
4. Coenzyme Q10 (CoQ10)
- Function: Naturally produced in the body, involved in energy metabolism and antioxidant defense.
- Evidence: Some studies suggest protective effects on heart cells during chemotherapy.
- Limitation: Large-scale clinical trials are still lacking for proven anti-cancer benefits.
5. Gerson Therapy
- Approach: Emphasizes organic diet, pancreatic enzymes, and coffee enemas.
- Limitation: No rigorous clinical trials support its efficacy. Not recommended as a primary cancer treatment.
6. High-Dose Vitamin C
- Evidence: Animal studies show tumor growth suppression.
- Clinical Findings: In humans, mainly shown to improve quality of life and reduce treatment side effects.
- Limitation: Results on survival or treatment synergy remain inconclusive.
7. Herbal Medicine and Botanicals
- Examples: Astragalus, mistletoe extracts.
- Evidence: Small studies suggest possible immune-modulating effects.
- Caution: Some herbs (e.g., green tea extracts, Essiac) may interact with chemotherapy drugs—use only under medical supervision.
8. Other Supplements
- Fish oil, ginseng, guarana fruit.
- Evidence: May help with fatigue and quality of life in some studies, but effects are modest.
Conclusion
Most complementary and alternative therapies remain at the experimental or supportive stage. While some approaches (e.g., acupuncture, certain supplements) may help manage side effects, standard medical treatment must remain the foundation of cancer care. Patients should always consult their oncologist or medical team before adding any CAM approach to avoid harmful interactions or treatment delays.
