Justicia pectoralis is a low growing, branching sprawling shrub, can grow up to 3 ft. It has small lanceolate leaves and violet flowers, similar in appearance to those of snapdragons.
In areas of the Central American Caribbean coast it is considered to have aphrodisiac properties. The entire plant is dried in the sun and made into a powder before being used. Notably, the powder is effective only when it is taken via the nasal membranes, (as snuff), or smoked (in conjunction with Cannabis sativa). In South America one variety, Justicia pectoralis var. stenophylla, is used to produce psychedelic experiences or used as an additive in ayahuasca (Banisteriopsis caapi). The plant contains psychedelically active tryptamines. A “tilo tea” is commonly seen sold in supermarkets, it has anti-inflammatory and relaxant effects.
