Morphology
This plant typically develops as a small tree or large shrub, reaching several meters in height. The branches bear large, pinnately compound leaves that form a dense canopy. Its small, greenish-yellow flowers are arranged in large, terminal panicles that emit a faint scent.
The fruits of Homalolepis cedron are large, egg-shaped drupes containing a single, large seed. This seed is exceptionally bitter and contains quassinoids, specifically cedronin, which serve as the primary bioactive components. The seed coat is tough, protecting the embryo within humid forest environments.
Applications
The primary application of this species lies in traditional medicine and pharmacology. Historically, the bitter seeds were ground and administered as a treatment for malaria, fevers, and snake bites. Modern scientific studies have investigated these claims, focusing on the anti-inflammatory and anti-parasitic properties of its quassinoid compounds.
- Antimalarial use: Used historically as an alternative to quinine in South America.
- Antivenom therapy: Traditionally applied topically or ingested as an antidote for venomous snakebites.
- Digestive aid: Infusions of the bark and seeds have been used to address stomach disorders.
Interesting facts
