Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Documented in early taxonomic literature as Sarcoca abyssinica, this species typically grows as a climbing or scrambling shrub. It features long, flexible stems that allow it to drape over surrounding vegetation. The plant is well known for the high concentration of saponins in its tissues, which play a significant role in its ecological interactions and historical uses.
Researchers have extensively studied the chemical compounds found within this plant. Its natural distribution covers various regions across the African continent, where it thrives in diverse habitats.
The foliage consists of ovate to elliptic leaves with entire margins and a somewhat fleshy texture. The inflorescences appear as elongated, densely packed racemes bearing numerous small, star-shaped flowers. As the reproductive cycle progresses, these flowers mature into lobed, reddish to purple fleshy berries that hold the seeds.
The berries contain potent saponins that lather when crushed in water, historically serving as a natural detergent in local communities. Extracts derived from the tissues have demonstrated molluscicidal properties in various scientific studies. Due to its high toxicity, the plant requires careful handling and is strictly non-edible.
The saponin-rich berries are famous for their historical use as a traditional detergent in several African communities. The botanical name reflects its early documentation from the region historically known as Abyssinia.
