Barleria lupulina Lindl.

Landik (Barleria lupulina) is a shrub up to 1-2 meters tall of the Acanthaceae family, native to Madagascar and distributed as far as Sumatra, Java, and Ambon. This plant has been shown to have antimicrobial and antiamebiasis activity in research, besides being popular as an ornamental hedge. Landik is traditionally believed to treat snake or dog bites and relieve swelling from impact.

Landik lives in forests or fields, growing well up to elevations of 300 m above sea level. Prefers open or slightly shaded places and can grow in almost all soil types, also resistant to hot weather. Climate does not greatly affect its growth.
