Research seems to support the following benefits of cumin:
1. Weight loss
Cumin may be helpful for people trying to their manage body weight. A 2015 study involving adults with overweight compared the weight loss effects of cumin with those of a weight loss medication and a placebo.
After 8 weeks, the researchers found that both the cumin and the weight loss medication groups lost significant amounts of weight. People in the cumin group also experienced a decrease in insulin levels.
Another study from 2014Trusted Source found that women with overweight and obesity who consumed 3 grams (g) of cumin powder in yogurt every day for 3 months had significant decreases in body weight, waist size, and body fat.
The aforementioned studyTrusted Source involving women with overweight and obesity also found that consuming 3 g of cumin powder per day resulted in lower levels of total cholesterol, lower low-density lipoprotein, or “bad,” cholesterol, and triglycerides.
Those who consumed the cumin powder also had higher levels of high-density lipoprotein, or “good,” cholesterol.
A 2017 studyTrusted Source in adults with type 2 diabetes looked at the effects of cumin essential oil on blood sugar levels. Study participants received either 100 milligrams (mg) of cumin oil per day, 50 mg of cumin oil per day, or a placebo.
However, other human studies using black cumin seeds have shown mixed results, according to a 2017 review of studiesTrusted Source. More research is necessary to confirm the benefits of cumin essential oil for those with diabetes.
4. Irritable bowel syndrome
After 4 weeks, study participants noted improvements in many symptoms, such as stomach pain and bloating.
When the animals received cumin extract before a stressful activity, their bodies had a significantly lower stress response than when they did not receive the extract.
6. Memory loss
The same study in rats also looked at the impact of cumin extract on memory. The study found that the animals who received cumin extract had a better and faster recall.
