Botanical Overview
Malabar Nut (Justicia adhatoda) belongs to the Acanthaceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The acanthus family (Acanthaceae) includes herbs and shrubs with opposite leaves and showy, two-lipped flowers with prominent bracts. The fruits are explosive capsules that eject seeds when mature. Many species contain alkaloids and have traditional medicinal uses.

General Description
