It would be extremely difficult. A lethal dose of fenugreek in rats equated to about 50g of fenugreek in humans.Ouzir, M., El Bairi, K., & Amzazi, S. (2016). Toxicological properties of fenugreek (Trigonella foenum graecum). Food and Chemical Toxicology: An International Journal Published for the British Industrial Biological Research Association, 96, 145-154. It’s certainly possible to eat 50g of fenugreek if you’re so determined, but the danger of an unintentional overdose or toxicity is low.
