Efficacy Of Various Spice Extracts In Combating Potential Stimulant Hazards

CSEF · 2023 Toxicology First Award

Jaimovich Adam, Sayed Zakari · 7

Overview

Caffeine pollution is a form of wastewater pollution prevalent in the United States and other parts of the globe. We hypothesized that certain spices might be able to counteract stressful stimulatory effects of caffeine in aquatic organisms. We obtained 200 Daphnia magna. Daphnia are a well-known invertebrate toxicology model. For test spices we selected turmeric, cinnamon, ginger, and garlic. We prepared 1%, 2%, and 5% test solutions, which we vortexed. Control heart rates for the Daphnia averaged from 140-170 bpm. In 0.5% caffeine, Daphnia heart rates rose to 200-270 bpm. Cinnamon and ginger rendered the Daphnia comatose. Surprisingly, garlic did not impact heart rate. In contrast, turmeric returned Daphnia heart rate to normal. Note that only one drop of test spice solution was added to the 0.5% caffeine infusion in which the Daphnia were tested. Experimental Daphnia treated with turmeric survived for many days and appeared healthy.
