  5. Whether Kaala jeera or nigella sativa which is availble in market can be used for diabetes treatment or not.If so how to take & what is the dose? Wherher to take raw or heated on pan Please clarify my doubt

  6. When I contacted an Ayurvedic doctor,he told that he does not have knowledge of Kalonji oil seeds.Further Dr Hebbar not confirmed to take seeds raw or advise us to take dose of Kalonji seed oil for diabetes.

  7. I am confused which is black cumin or nigella sativa seeds. There are two different spices shown in the net. One that looks like black sesame and the other which looks like a blacker version of cummin. So when the concoction says black cummin which do I use. I have a combination of black cummin (1part) : fenugreek (5part) : ajwain (2part). All to be toasted lightly n ground. A teaspoon to be consumed with a glass of water after food for cleansing and well being of body. Lease advise if this is okay Abd which black cummin to use. Thanks.

    • Hi, Black cumin is black variety of cumin.

  8. Hello Dr hebbar,

    I made mixture of Methi,Ajwain and Nigella sativa(Kalonji) .AS there is difference betwwen Kala Jera and Kali jeeri.What are best to use from there.?

    i made power of Methi (200) ,Ajwain (100) and Kalonji (50gm).Shall i add Kali Jeeri(centratherum anthelminticum) (50gm) to it?Would it have any effects?I think there ratio will be different.

    please guide me..thank you.

    • Good combination. 3 grams, 2 times a day, after food with water for 2 months is good to take.

    • It is more used for cleansing and detoxifying, rather than nutrition purpose. Hence, it would not be very useful for the said purposes.

    • Not if taken just for two weeks. It is cleansing in nature. And cleansing action is not required during pregnancy

  9. Recently ,i have purchased Manjistha.Would this combination of Methi (200) ,Ajwain (100) and Kalonji (50gm) Kali Jeeri(centratherum anthelminticum) (50gm) and 50-100 gm Manjistha be helpful?
    Please suggest me..

    • Useful in diabetes, bodyache, high cholesterol, high BP, recurrent fever, low immunity, low metabolism, to relieve ama and obesity.

    • There is no need to control blood sugar when we are not diabetic. Just adopting healthy eating and lifestyle habits are good enough.
      Avoid junk foods, aerated drinks, soda and fizz drinks.

  10. There seems to be another one called Kala Jeera (aka ‘black cumin’) used in cooking in northern India. I believe it’s called Bunium persicum. Vernonia is not outdated, and is replaced with Centratherum (anthelminticum). All of them have been indiscriminately called ‘black cumin’. Can you beat that thickheadness?!

  11. Doctor, please clarify whether the proportional combination of these three (mehthi, ajwain and karunjeera) will detoxify the allopathic medicines taken earlier for szhizophrenia for the past 5 years from the body and back to normal body shape ?

    • Rarely the taste and veerya rule does not apply to vrushya action. For eg ashwagandha pippali etc

  12. These seeds are unpalatable and difficult to chew. Anyone have ideas on how best to take them? Also is a teaspoon about a gram? I don’t have a scale.
