What is the ld50 of black pepper?

The LD50 (lethal dose for 50% of the population) of black pepper, specifically its active compound piperine, is not well-documented in scientific literature. However, it is generally considered to have a low toxicity, and estimates suggest that the LD50 for piperine in rats may be around 1,200 mg/kg. For practical purposes, black pepper is commonly used as a spice and is safe for consumption in normal dietary amounts. Always consult with a medical professional for specific health concerns.
