Medicinal

Java tea is a popular herbal remedy in southeast Asia and is also commonly exported to Germany and various other countries. Research has confirmed the presence of a number of medically active compounds and also the diuretic action of the leaves

The leaves contain flavones (including sinensetin), saponins, a glycoside (orthosiphonin), an essential oil and large amounts of potassium (which is largely responsible for the diuretic effect)


In tests with healthy volunteers in Thailand, extracts of the plant increased excretion of citrate and oxalate. Although a higher level of oxalate may increase the risk of kidney stones, the increased citrate output helps prevent stone formation

It has been demonstrated that Java tea has anti-microbial properties. Aqueous extracts markedly inhibited the growth of both gram-positive and gram-negative bacteria

Saponins may play a role in bacteriostatic activity in vitro

Caffeic acid derivatives (which represent as much as 95% of the phenolic substances present in a hot water extract) may also be responsible for the antibiotic activity

The lipophilic flavonoids, of which sinensetin and tetramethylscutellarein are the most abundant, have shown inhibitory effect against Ehrlich ascites tumour cells in vitro
Additionally, these flavonoids may be partially responsible for anti-inflammatory effects, since flavonoids are inhibitors of cyclo-oxygenase and lipoxygenase

The crude herb is said to cause vomiting


The leaves are strongly diuretic and are believed to increase the kidneys' ability to eliminate nitrogen-containing compounds

They are used in the treatment of kidney infections, kidney stones and poor renal function as a result of chronic nephritis

They are also used in the treatment of cystitis, urethritis and gout

They are used, in combination with other plants such as Sonchus spp or Barleria spp, to stimulate the kidneys and as a medicine for nephritis, gallstones and diabetes

Combined with the leaves of Blumea balsamifera and Phyllanthus fraternus, plus the rhizomes of Curcuma xanthorrhiza, the leaves are used to treat jaundice

Combined with the leaves of Andrographis paniculata, they are used to treat diabetes

In mixtures with the leaves of other plants, they are also used against gout, rheumatism and arteriosclerosis
