The researchers wanted to see if consuming nettle oil could help lower blood sugar and fat levels in diabetic rats. They used male Wistar rats and divided them into different groups. They induced diabetes in some rats and then gave them nettle oil. The results showed that the rats with diabetes who were given nettle oil had higher blood sugar levels compared to the control group. They also had increased cholesterol and triglyceride levels, and lower levels of HDL (good cholesterol). Overall, the study suggests that nettle oil consumption may not be effective in lowering blood sugar and fat levels in diabetic rats.
