  1. I had read Datura seeds and black pepper formula in social media site and then I started taking this in Jan 2015. I was also taking other medications advised by the doctor. My blood sugar level becomes normal from 220 mg/dL.

    After around 40 days, from mid February 2015, when I take medications advised by the doctor, it decreases my sugar level from the normal range and once I had hypoglycemia on 16 Feb.

    Now, my doctor suggested stopping medications and regularly checking blood sugar level. I am checking blood sugar level daily after hypoglycemia attack. It is always normal and varies from 80 to 100 mg/Dl without medications.

    I also stopped taking datura seeds powder and I am just now eating black pepper powder. My blood sugar level is under good control alone with black pepper. I consider black pepper safe spice and we can use it on long-term basis. I stopped taking datura seeds because I am not sure about its safety for a longer period.
