Orthosiphon (Orthosiphon stamineus (O. aristatus) Lamiaceae/Labiatae)

Other Names: Cat's Whiskers, Java Tea

Orthosiphon, a Southeast Asian shrub, grows up to 1 meter with irregularly serrated, oppositely paired leaves. Its white or purple flowers, featuring long, shaggy anthers resembling cat's whiskers, bloom prominently.

Parts for Use

Leaves and Flowers

1. Harvested at the start of flowering, then dried and crushed.
2. Used to prepare infusions, capsule powders, and extracts.

Ingredients

Orthosiphon is rich in polyphenols, particularly flavonoids like sinensetin, and contains high potassium levels with minimal essential oil.

Use in Treatment

Orthosiphon is valued for treating gout, rheumatism, urinary tract infections, kidney stones, gallstones, and diabetes. A 1998 human study confirmed its mild diuretic effect, increasing urine and uric acid excretion. A 2001 Thai study showed daily orthosiphon infusions were as effective as conventional drugs for kidney stones, without side effects, boosting calcium and uric acid excretion. Some terpene compounds in its leaves may slow cancer cell proliferation. Its diuretic and bile-stimulating properties make it a common adjunct in weight loss programs.

Cultivation

Grow orthosiphon in well-drained soil in a sunny or slightly shady location.
