Summary
Cola acuminata, also known as kola nut, is a tropical plant species used as a stimulant and flavoring ingredient [PMID:19394393, PMID:3508643].
Background
Cola acuminata is a multicotyledonous species of kola nut growing wild and cultivated in the equatorial rain forest belt of Nigeria and other West Coast African regions [PMID:3508643]. It is derived from the seeds of the Sterculiaceae family [PMID:19394393].
Traditional uses
It is used as a stimulant in Nigeria [PMID:25506036] and has been reportedly used in folklore for the management of neurodegenerative diseases [PMID:25506036].
Active compounds
The plant contains xanthines, specifically caffeine, theobromine, and theophylline [PMID:19394393, PMID:3508643]. Phytochemical analysis shows the presence of alkaloids (2.22%), tannins (6.46%), and saponins (8.06%) [PMID:24511707]. It also contains polyphenolic compounds such as (+)-catechin, (-)-epicatechin, procyanidin B1, and procyanidin B2 [PMID:17979235].
Mechanism of action
In vitro studies indicate that Cola acuminata extract inhibits the NLRP3 inflammasome, reducing the release of IL1-β and IL-18 cytokines and inhibiting NF-kB expression [PMID:40536624]. It also demonstrates anticholinesterase activity by inhibiting acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) [PMID:25506036, PMID:30020887].
Clinical evidence
Evidence CWeight loss
Lacks controlled clinical trials to support its use [PMID:10516985]
Evidence DNeuroinflammation/Parkinson's Disease
In vitro evidence shows inhibition of NLRP3 inflammasome and increased phagocytic activity of macrophages toward amyloid-β [PMID:40536624]
Evidence DGastric acid secretion
Significantly stimulates gastric acid secretion [PMID:3508643]
Safety & adverse effects
Kola nut extract has a history of safe consumption in cola-type beverages in the U.S. [PMID:19394393]. However, it contains aliphatic amines (such as dimethylamine and methylamine) and exhibits methylating activity [PMID:7672735].
Evidence summary
The current evidence is primarily based on in vitro studies and phytochemical analyses; there is a noted lack of controlled clinical trials for therapeutic claims such as weight loss.
