Locust Bark

Description

Hymenaea courbaril L. var. courbaril

LEGUMINOSAE-CAESALP.

Locust
Vernacular names: Locust, Stinking toe (Cr), Kawanari (Ar), Simiri (C), Kahawanaru arau (Wr).

Use: The woody pods are broken open with a hammer or cutlass to consume the powdery, soursweet
seed pulp. In spite of their smell of stinking feet, the fruits are much prized. When gathering the pods,
they must be shaken: if they rattle, weevils have infested the seeds; if they produce no sound, they are
still good. Locust trees are spared when farmers clear forest for agriculture.
A popular beverage is made from the bark. A piece of ca. 25 x 5 cm is cut off and the rough outer
layer is scraped off. The bark is dried in the sun; fresh bark is not used. When dry, the bark is
chipped, boiled, and drunk with milk and sugar, just like chocolate milk. Locust trees along
frequently used forest trails in Moruca were stripped from nearly all their bark at man’s height. The
bark tea is also drunk against colds, back pain, diabetes, and general body pain. Aphrodisiacs are
made with locust bark and some of the following ingredients: cockshun root (Smilax
schomburgkiana), kapadula wood (Tetracera spp., Pinzona sp., Doliocarpus sp.), kufa root (Clusia
spp.), sarsparilla root (Dioscorea trichanthera), monkey ladder wood (Bauhinia spp.), granny
backbone wood (Curarea candicans), and devildoer wood (Strychnos spp.). The ingredients are
soaked in alcohol or boiled in water, and added to milkshakes, porridge, or other dishes. These
‘builders’ are said to protect against diseases, stimulate sexual activities, and help against a ‘weak
back’ (impotence). Stories were told of coastlanders who accidentally took the bark of soapwood
(Abarema jupunba) or aromatta (Alexa imperatricis) for locust and died of poisoning after drinking
the tea.
In coastal Guyana, locust bark is boiled with the barks of guava (Psidium guajava), jamoon
(Syzygium cumini), starapple (Chrysophyllum cainito), the skins of pomegranate (Punica granatum),
and orange (Citrus sinensis). A small glass is taken three times a day for the relief of ‘bilious
diarrhoea’ (Lachman-White et al., 1992). Fanshawe (1948) reported an excellent cure for dysentery
from a decoction of the barks of locust, tauroniro (Humiria balsamifera), and bulletwood (Manilkara
bidentata). He also reported about an infusion of the bark to bathe ulcers, and that continuous
drinking of locust tea caused constipation. Various terpenes and acids have been isolated from the
bark (Grenand et al., 1987; Lachman-White et al., 1992). The heavy, hard, and durable wood is
commercially marketed for house construction and furniture. In the interior, locust wood is preferred
for canoes.
