Insights
This review found limited evidence that cupping therapy effectively treats hypertension. More research is needed to confirm cupping
Area of Science:
- Integrative and Complementary Medicine
- Cardiovascular Health
Background:
- Hypertension is a global health concern requiring diverse treatment options.
- Cupping therapy is a traditional practice with proposed benefits for various conditions.
Purpose of the Study:
- To critically evaluate the existing clinical evidence for cupping as a hypertension treatment.
- To determine the efficacy and safety of cupping therapy for managing high blood pressure.
Main Methods:
- A comprehensive literature search was conducted across 15 databases up to June 2009.
- Included studies were clinical trials (CTs) involving cupping for hypertension in humans.
- Risk of bias was assessed using the Cochrane criteria.
Main Results:
- Two clinical trials met the inclusion criteria.
- One randomized controlled trial (RCT) indicated potential benefits of dry cupping on vascular compliance.
- One uncontrolled observational study suggested wet cupping may acutely reduce blood pressure.
Conclusions:
- Current evidence is insufficient to conclusively support cupping for hypertension treatment.
- Further high-quality research is necessary to establish the specific effects and clinical utility of cupping therapy.
Abstract:
The objective of this review is to assess the clinical evidence for or against cupping as a treatment for hypertension. We searched the literature using 15 databases from their inception to 30 June 2009, without language restrictions. We included all clinical trials (CTs) of cupping to treat hypertension in human patients. Risk of bias was assessed using the Cochrane criteria. Two CTs met all inclusion criteria. One RCT (randomized CT) assessed the effectiveness of dry cupping on changes in cerebral vascular function compared with drug therapy. Their results suggested significant effect in favor of cupping on vascular compliance and degree of vascular filling. One uncontrolled observational study (UOS) tested wet cupping for acute hypertension and found that a one-time treatment reduced blood pressure. In conclusion, the evidence is not significantly convincing to suggest cupping is effective for treating hypertension. Further research is required to investigate whether it generates any specific effects for that condition.
