Akuamma seeds or Picralima Nitida is an herbal medicine used in different part of Africa as a painkiller. The seeds contain various types of alkaloids which include akuammine and pericine. These alkaloids possess skeletal muscle relaxant, anti-inflammatory, anti-oxidant, anti-diarrheal, antimicrobial, antipyretic, antiplasmodial and antiulcer activities.

Akuamma seeds resemble Kratom in a way because its alkaloid akuammine is related to mitragynine and yohimbine. Studies reveal that Akuamma seeds can be employed as a remedy for fever, hypertension, jaundice, dysmenorrhea, malaria and gastrointestinal disorders.

These seeds are crushed and taken in powdered form, but they have a very bitter taste so usually they are capsulated and sold under the name Picap. The powdered form of seeds can be mixed with food too.

Alkaloids Present in Akuamma Seeds

The two main groups of alkaloids are Akuammine and Pericine. Akuammine acts on delta and kappa opioid receptors.


It is the primary alkaloid found in the seeds. Structurally it is related to kratom, and it shows the greatest affinity for kappa receptors, making it kappa agonist at opioid binding sites. It has threefold action as a skeletal muscle relaxant, hypotensive action, and local analgesic action. It also has sympatholytic effects.


It is an antagonist at mu receptor. It is a sympathetic system agonist. Its effects resemble that of cocaine. It inhibits intestinal motility and shows a fall in blood pressure. However, at higher doses, it shows hypertension.


It binds strongly to the kappa opioid receptors.


It shows analgesic and anti-inflammatory actions. It acts as an indirect competitive parasympathomimetic. At small doses, it excites the Central nervous system, respiratory system, nervous system, and enhances muscle contractility; at high doses, it causes depression of all these systems.


It is an antagonist of adrenaline and shows the antiadrenergic activity of the heart, vessels and regulatory center of the circulatory system.


It binds to mu-opioid binding receptors. It shows convulsant effects.
Other alkaloids include Picraline, Picraphylline, Picracine, Picranitine, Burnamin and Desacetylakuammiline.

Anti-malarial action

Picralima nitida seeds and other parts of fruit and stem bark have been investigated in vitro for antimalarial action. The seeds showed inhibitory activity against the resistant strains of Plasmodium such as Falciparum. Two alkaloids akuammine, and alstonine are important in the therapy of malaria Thus it is considered as a potential antimalarial drug.
