Tobacco plant compound reverses diabetes damage in mouse study

Medicinal Plants
The waxy coating on tobacco and tomato leaves in your garden contains solanesol, a compound now shown to repair liver and kidney damage in diabetic mice by reshaping their gut bacteria.
Solanesol is a natural substance found in plants like tobacco, tomatoes, and potatoes that belong to the nightshade family. Scientists gave it to diabetic mice and found it lowered blood sugar, cut down harmful fat buildup in the liver, calmed inflammation in the pancreas and kidneys, and boosted good gut bacteria, all while working through several different pathways in the body at once. It performed alongside the standard diabetes drug metformin, hinting that this plant compound might one day help treat diabetes in people too.
Key Findings
Solanesol (1-15 mg/kg/day) improved glucose tolerance and insulin sensitivity comparably to metformin (200 mg/kg/day) in diabetic Leprdb/db mice over 8-13 weeks
It enriched beneficial gut bacteria (Alistipes, Anaerotruncus, Parasutterella) and increased long-chain unsaturated fatty acids, reducing white adipose mass and hepatic steatosis
It reprogrammed liver lipid metabolism by suppressing the Acly-Acaca-Fasn fat-production pathway while activating Abca1/Fabp5 for cholesterol clearance and fat burning

A tobacco-plant compound called solanesol helped diabetic mice control blood sugar, protect their liver, kidneys, and pancreas, and grow healthier gut bacteria, all with fewer side effects than typical diabetes drugs. The findings suggest a plant-derived molecule could one day support treatment for type 2 diabetes in humans.
