What is Java Tea (Cat Whiskers or Poonai Meesai)?
This tea is a medicinal herb belonging to the Lamiaceae family — the same family as mint and basil. It is native to Southeast Asia, particularly Indonesia, Malaysia, Thailand, and parts of India. The plant is an evergreen shrub that grows up to 1.5 meters tall and bears small, white or pale purple flowers with long, protruding stamens that look like the whiskers of a cat — hence the name Cat Whiskers.
In India, especially in Tamil Nadu, the plant is affectionately known as Poonai Meesai, and in Malaysia and Indonesia, it’s called Misai Kucing. The leaves of the plant are the main medicinal part, often dried and brewed into tea or used in herbal formulations.
Origin and Historical Background
The use of This Tea dates back centuries, particularly in Javanese and Malay traditional medicine. It was widely consumed as a natural diuretic to treat kidney and bladder disorders. The herb gained international recognition during the Dutch colonial period in Indonesia, when it was exported to Europe under the name “Java Tea” due to its strong connection with the island of Java.
In Ayurveda, similar herbs are recognized for their ability to cleanse the urinary tract and balance pitta and kapha doshas. Likewise, in Traditional Chinese Medicine (TCM), Cat Whiskers has been used to eliminate dampness, improve urination, and support liver detoxification.
Today, the herb is gaining renewed interest in modern herbalism due to scientific studies supporting its antioxidant, anti-inflammatory, and antidiabetic effects.

Health Benefits of Java Tea (Cat Whiskers / Poonai Meesai)
Supports Kidney Health
