Soursop Leaves for High Blood Pressure: What the Evidence Says and How to Use Them Safely
Soursop leaves are widely used in Nigeria for high blood pressure, and there is some science behind the tradition. In animal studies, soursop leaf extract lowered blood pressure. But there are no good human trials showing that soursop tea reliably controls high blood pressure, and it is not a replacement for blood pressure medicine. The biggest risk is combining the two: soursop on top of your tablets can push your pressure too low. If you want to try soursop tea, talk to your doctor first, keep to sensible amounts, and check your blood pressure at home. Here is what the research shows and how to use it safely.
Important: never stop or reduce your blood pressure medicine to use soursop instead. Uncontrolled high blood pressure can lead to stroke, heart attack and kidney damage, often without warning signs.
Does soursop lower blood pressure? What the research says
- Animal studies: studies in rats found that soursop leaf extract lowered blood pressure, apparently by relaxing blood vessels.
- Human studies: there are no good-quality clinical trials showing soursop tea lowers blood pressure in people with hypertension, or at what dose.
- Traditional use: many Nigerian families drink soursop tea for blood pressure, and it is often mentioned by people who also take medicine, which makes it hard to know what is helping.
So: possibly helpful, not proven, and not a substitute for treatment.
The real risk: soursop plus blood pressure tablets
If soursop does lower blood pressure, adding it to medicines like amlodipine, lisinopril or hydrochlorothiazide could drop your pressure too far. Watch for:
- dizziness or light-headedness, especially when standing up
- fainting or feeling faint
- unusual tiredness or blurred vision
If these happen, stop the tea, sit or lie down, and contact your doctor.
How to use soursop tea for blood pressure, safely
- Talk to your doctor first, especially if you take any blood pressure or diabetes medicine.
- Prepare it gently: 5 dried leaves in one to two cups of water, boiled 10 to 15 minutes and steeped 10 minutes. See how to prepare soursop leaves.
- Keep to one or two cups a day, and take regular breaks.
- Check your blood pressure at home before you start and regularly afterwards. Write the readings down and share them with your doctor.
- Don't change your medicine based on how you feel. Only your doctor should adjust it.
Who should not use soursop for blood pressure
- anyone with low blood pressure or frequent dizziness
- pregnant or breastfeeding women. High blood pressure in pregnancy needs medical care.
- people with Parkinson's disease, or kidney or liver disease
- people already on several blood pressure medicines, unless their doctor agrees
