Overview Information

Java tea is a plant. The leaves and stem tips are used to make medicine.

Java tea is most commonly used by mouth for treating various conditions of the urinary tract, bladder, and kidneys. But there is limited scientific research to support these uses.

How does it work?

Java tea might increase the loss of body water through the urine (diuretic effect), stop spasms, reduce swelling, and help fight bacteria.


Uses & Effectiveness?

Insufficient Evidence for

  • High blood pressure.
  • Infections of the kidney, bladder, or urethra (urinary tract infections or UTIs).
  • Liver complaints.
  • Bladder and kidney disorders.
  • Gallstones.
  • Kidney stones.
  • Gout.

Side Effects

Side Effects & Safety

When taken by mouth: Java tea is POSSIBLY SAFE when taken by mouth for up to 8 weeks.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if Java tea is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Fluid retention (edema): Don't use Java tea as "irrigation therapy" if you have heart or kidney problems.

Low blood pressure: There is some concern that Java tea might lower blood pressure. If your blood pressure is already too low, this might be a problem.

Surgery: There is a concern that Java tea might make blood pressure control difficult during surgery. Stop taking Java tea at least 2 weeks before a scheduled surgery.



Moderate Interaction

Be cautious with this combination

  • Lithium interacts with JAVA TEA

    Java tea might have an effect like a water pill or "diuretic." Taking java tea might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.



The appropriate dose of Java tea depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for Java tea. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
