People have used the seeds as medicine for more than 2,000 years , in Persian, Islamic, Egyptian and Ayurvedic practice. High blood sugar and type 2 diabetes Good evidence — more than one human trial of black seed supplements; sizes and doses are not on file. In these trials, people taking black seed had lower fasting blood sugar. Their bodies also seemed to use insulin better. Our file does not list the trial sizes or the doses used. Evidence grade B · Traditional tier T3 High cholesterol Good evidence — human supplement trials with steady results across studies. Across trials, people taking black seed had lower LDL, the "bad" cholesterol. Their triglycerides fell too. HDL, the "good" kind, rose only a little. Evidence grade B · Traditional tier T3 High blood pressure Good evidence — several clinical trials of black seed oil. In several trials, both the top and bottom numbers went down. The drops were small but real. In these studies, the oil seemed to relax blood vessels and act as a mild water pill. Evidence grade B · Traditional tier T3 Asthma and wheezing Good evidence — clinical trials in people who already had asthma. Trials tested black seed oil in people with asthma. Those taking it wheezed less and scored better on lung tests. They also reported fewer attacks. Evidence grade B · Traditional tier T3 Extra weight and waist size Good evidence — several trials in people who were overweight. In these trials, people lost a small amount of weight. Waist size and BMI dipped as well. The changes were bigger when people also changed what they ate. Evidence grade B · Traditional tier T3 Joint pain and morning stiffness Early evidence — clinical trials in rheumatoid arthritis, based on what people reported. People with rheumatoid arthritis used black seed oil in these trials. They reported less joint swelling and less stiffness in the morning. Some studies compared thymoquinone, a compound in the seed, with common anti-swelling drugs. Evidence grade C · Traditional tier T3 Hay fever and other allergies Early evidence — early human studies of the oil, plus lab work on the plant compounds. Early studies found less sneezing, runny nose and itchy eyes. In lab work, a compound called nigellone acted like a mild antihistamine. Lab work also showed thymoquinone calming an immune overreaction. Evidence grade C · Traditional tier T3 Eczema and psoriasis patches Early evidence — small studies of the oil put on the skin. People in these studies rubbed black seed oil on the skin. Redness, itching and scaling went down. In lab work, the oil calmed swelling and slowed some germs. Evidence grade C · Traditional tier T3 Bloating, gas and stomach cramps Early evidence — small clinical studies, plus long traditional use. Small studies looked at everyday gut complaints. People reported less bloating, gas and cramping. In lab work, the seed relaxed gut muscle and slowed some gut bacteria. Evidence grade C · Traditional tier T3 What Black Cumin Seed has not been shown to do It has not been shown in people to prevent colds or flu; that use rests on tradition and lab work only. It has not been shown to replace blood pressure medicine, since the drops seen in trials were modest. It has not been shown to replace diabetes medicine or insulin. It has not been shown to give fast relief during an asthma attack; the trials tested steady use over time. It has not been shown to clear eczema or psoriasis; studies only tracked redness, itching and scaling. It has not been shown to cause large weight loss on its own; the best results came with diet changes. How to read this: The grades here are about proof, not strength. A means many good human trials agree. B means at least one good human trial. C means small or mixed human studies. D means the human evidence is weak or clashes. "Insufficient" means no human study a

This app is so cool! I've always wanted there to be a hub for all NATURAL remedies and preventative options but l've always had to do loads of digging to find the info I wanted for different natural products. HealisticMD has all the info I need in one place. It gave me various natural supplemental options for a condition I looked up, including what each remedy does and how much is usually recommended to take. It also gave me exact products I could buy for the problem I had looked up. It makes my process SO MUCH easier when I need to find non-pharmaceutical solutions to my needs.

There is a wealth of information on the app! I recently had bloodwork done and found I was deficient in a handful of vitamins and minerals (Vitamin B12, Vitamin D, Iron, etc.) HealisticMD made it simple for me to find out what foods to eat/ supplements I needed to improve these deficiencies. It gives you so many ideas on prevention, natural health tips, where to buy the vitamins, when to take them, why, etc. I love how easy the app is to use too. I am currently working on getting pregnant. I was pleasantly surprised to find compelling data along with supplement suggestions to aid in the process, some of which my fertility doctor wasn’t even aware of. Highly recommend downloading, after all health is one our greatest gifts!
