Question 1

How does Daun Dewa lower blood pressure?

Accepted Answer

Daun Dewa contains flavonoids and alkaloids that may lower blood pressure through vasodilation and mild diuretic effects. These compounds help relax blood vessel walls and promote fluid excretion, reducing vascular resistance. Laboratory studies suggest antioxidant properties that may protect cardiovascular tissue from oxidative stress. However, human clinical trials are limited. Evidence Level: C, based primarily on animal and in vitro research rather than large-scale human studies.

Question 2

Can I take Daun Dewa with blood thinners like warfarin?

Accepted Answer

Daun Dewa should not be combined with anticoagulant or antiplatelet medications. The herb possesses blood-thinning properties that may enhance the effects of drugs like warfarin, aspirin, or clopidogrel, significantly increasing bleeding risk. This interaction could lead to prolonged bleeding times, easy bruising, or hemorrhage. Patients on blood-thinning medications should avoid Daun Dewa entirely and consult their healthcare provider for alternative options. Evidence Level: C.

Question 3

What is the recommended dosage for Daun Dewa?

Accepted Answer

The traditional adult dosage for Daun Dewa is 30-60 grams of fresh leaves daily, typically prepared as a tea or decoction. Fresh leaves may be boiled in water and consumed once or twice daily. Standardized commercial extracts are not well-established, so traditional fresh leaf preparations remain the primary recommendation. Start with lower doses to assess individual tolerance. Evidence Level: C, based on traditional Jamu practice rather than clinical trials.

Question 4

Is Daun Dewa safe during pregnancy and breastfeeding?

Accepted Answer

Daun Dewa is considered unsafe during pregnancy and breastfeeding. The herb contains pyrrolizidine alkaloids, which are hepatotoxic compounds that can cross the placenta and pass into breast milk. These compounds may cause serious liver damage in both mother and developing fetus or nursing infant. Pregnant and breastfeeding women should avoid Daun Dewa entirely. Evidence Level: C, based on constituent analysis and established pyrrolizidine alkaloid toxicity profiles.

Question 5

What are the side effects of long-term Daun Dewa use?

Accepted Answer

Long-term Daun Dewa use may cause hepatotoxicity due to its pyrrolizidine alkaloid content. Extended consumption has been associated with liver damage, including potential veno-occlusive disease. Other possible side effects include digestive upset and allergic skin reactions. Users should limit duration of use and consider periodic liver function monitoring. Evidence Level: C, based on constituent toxicity profiles and traditional safety observations.

Question 6

What is Daun Dewa used for in traditional medicine?

Accepted Answer

Daun Dewa (Gynura pseudochina) is traditionally used in Indonesian Jamu medicine for treating hypertension, blood clots, wounds, and as a general anti-inflammatory agent. The herb has gained attention for potential anti-tumor properties and blood pressure-lowering effects. Fresh leaves are commonly applied topically for wound healing or consumed as tea for cardiovascular benefits. Evidence Level: C, supported by preliminary research and traditional use.
