Orthosiphon: Properties and Contraindications
Orthosiphon, also known as cat’s whiskers, is a herbaceous plant with the scientific name Orthosiphon aristatus. It usually grows in the soils of southern China, Southeast Asia, and Australia. However, it has also been introduced in some regions of Central and northern South America. It belongs to the family labiatae or lamiaceae, of which basil is also a member.
In its countries of origin, this species is used for ornamental purposes, due to its striking white flowers. It’s also used in the form of tea or extracts for various medicinal purposes. In this article, we’ll you what its main applications are, what the evidence says, and information about its contraindications.
Uses and properties of orthosiphon
Often, orthosiphon leaves are used for the preparation of infusions. In fact, it’s known on the market as Java tea. It’s important to note that other parts of the plant have toxic components and aren’t edible.
However, evidence on the safety and efficacy of this plant is still limited. Because of this, it isn’t a first-choice treatment and should be used with caution. Let’s take a look at its most common uses.

As mentioned in a review article reported in the Journal of Medicinal Food , orthosiphon has diuretic properties that are used to stimulate the elimination of fluids and fight inflammation. In particular, substances known as sinensetin and tetra methoxy-flavones would be responsible for this effect.
Due to its ability to stimulate the flow of urine, extracts of this plant are believed to promote bladder cleansing. In fact, it’s a popular remedy for conditions such as cystitis. In a study on mice reported in Phytomedicine, orthosiphon was useful in fighting an infection of the bladder and urinary system.
Java tea isn’t a first-line treatment for diabetes. However, evidence suggests that it may have a hypoglycemic effect that helps to reduce high glucose levels. It is important to use it sparingly, as a preventive measure only. If you are taking medication for diabetes, it’s best to avoid taking it.
In folk medicine, orthosiphon is considered a “fat-burning” ingredient. However, to date, there are no studies or scientific references to support this effect. On the contrary, it has been made clear that tea from the plant doesn’t burn stored fat reserves. Still, it appears to be an ideal weight loss supplement.
An ethanolic extract of the leaves was reported by Planta Medica to help reduce body weight gain. It was even helpful in lowering high cholesterol and triglyceride levels. Despite these results, more research is needed.
