Fenugreek (Helba)

Fenugreek (helba) is one of the few kitchen-cupboard herbs with real clinical backing: pooled across 26 randomized trials, it meaningfully lowers fasting blood sugar, which is why it's taken seriously as a diabetes adjunct rather than dismissed as folklore - and unlike many botanicals, it doesn't appear to harm the liver. But 'works' and 'harmless' aren't the same thing, and fenugreek is a clean example. The same potency that helps blood sugar means it stacks with diabetes treatment and can push you too low. More importantly, the reproductive signal is real: it has abortifacient and anti-implantation activity and teratogenic reports, so concentrated supplement doses are not for pregnancy (the everyday spice amount in food is a different matter). It also quietly cuts iron absorption - relevant if you're already managing low iron - and because it's a legume, it can trigger peanut or chickpea allergies. Used sensibly by the right person from a standardized source, it's a legitimate tool; used blindly, it has more edges than its 'natural seed' image suggests.
