It is a common herb growing up to 75 cm (30 in) tall with ovate leaves. Flowers are green, unisexual found in catkin inflorescence.
Acalypha indica occurs widely throughout the tropics of the Old World. In Africa it occurs in Nigeria in West Africa and further widely throughout tropical Africa and the Indian Ocean islands. It also occurs in India, South East Asia, and Oceania. It has been introduced to areas of the new world with favorable climates.
Throughout the area where the plant grows, it is widely known for its effect on domestic cats, which react very strongly and favorably to the root of the plant. In this regard it is very similar to catnip, but the effect is much more pronounced. Due to this ability it is called as Poonamayakki in Tamil, and Pokok Kucing Galak (Excited Cat Tree) in Malay.
The chemical compounds acalyphine and triacetoneamine have been extracted from A. indica. Other chemical constituents include cyanogenic glucosides and alkaloids.
