Background: Cyanide is a very toxic chemical that reacts with the ferric cytochrome oxidase in the mitochondrial system to form a stable complex. This complex inhibits the process of oxidative phosphorylation, thereby interrupting aerobic respiration in the organism. It is postulated that activated charcoal (AC) intercepts the ingested cyanide in the gastrointestinal tract before it is absorbed into the system. Methods: A single dose of 3 mg/kg body weight of potassium cyanide (KCN) was orally administered to the rats in each of the five groups, each consisting of 6 rats. After 15 minutes, all rats in each group were given AC from different agro-based materials. The control group (group 1) received standard commercial AC orally at 1 g/kg. group 2 received AC from plantain peels, group 3 received AC from castor oil seed shell, group 4 received AC from coconut shell and group 5 received a combination of AC from plantain peels, castor oil seed shell, and coconut shell. Blood samples were collected sequentially from rats in each group for biochemical assays using standard procedures. Results: The control group, which received KCN and standard commercial AC, exhibited the highest alanine transaminase (ALT) value (60.09±0.10 U/L) on day seven. Similarly, the highest aspartate transaminase (AST) value (196.28±0.72 U/L) was observed in the control group. Alkaline phosphate (ALP) levels followed a similar pattern. On day seven, the serum creatinine levels were 3.81±0.11 mg/dL for group 1 and 3.45±0.05 mg/dL for group 5. Subsequently, all biochemical parameters decreased after day 7, with the lowest levels recorded in rats that received AC derived from coconut shells. Conclusion: The administration of locally prepared agro-based adsorbents to Wistar rats after exposure to sublethal doses of cyanide significantly mitigated the effects of the cyanide on the liver, kidneys, and heart, as indicated by the biochemical parameters of the albino Wistar rats in the study.
