Sayer Ji on black seed oil
Sayer Ji’s best-known writing on black seed (Nigella sativa, the source of black seed oil) is “Black Seed: ‘The Remedy for Everything but Death,’” published on GreenMedInfo on January 3, 2013. It catalogs published research on the seed. He does not sell a black seed product.
What the article says
The article reports that 656 peer-reviewed studies had referenced black seed since 1964, and that GreenMedInfo had indexed research on more than 40 health conditions and more than 20 pharmacological actions, including anti-inflammatory, antioxidant, antibacterial and insulin-sensitizing effects (GreenMedInfo, 2013). A follow-up, “16 More Reasons Black Seed Is ‘The Remedy for Everything but Death,’” added further studies (GreenMedInfo).
Where the title comes from
The title quotes a traditional saying, attributed in Islamic tradition to the Prophet Muhammad, that black seed is “a remedy for all diseases except death.” The article presents it as the seed’s historical reputation, not as a medical claim (the article).
The human trial it highlights
The article cites a 2010 study in the Indian Journal of Physiology and Pharmacology. In it, 94 adults with type 2 diabetes were randomly assigned to 1, 2 or 3 grams a day of black seed capsules for 12 weeks, on top of their usual medication. At 2 grams a day, fasting blood glucose and HbA1c fell significantly and insulin resistance decreased; 1 gram showed non-significant trends, and 3 grams added no further benefit. The authors concluded black seed “might be a beneficial adjuvant to oral hypoglycemic agents” (Bamosa et al., 2010, PubMed).
How to read it
GreenMedInfo links each study to its PubMed record. Before relying on any finding, open the study and check whether it was done in people, animals or cells, how many participants it had, and whether it had a control group. The 2010 trial above, for example, compared doses and did not report a placebo group. The article carries the disclaimer that it “is not intended to provide medical advice, diagnosis or treatment.” Talk to a clinician before using black seed, especially alongside diabetes or blood-pressure medication.
Disclosure: Sayer Ji owns GreenMedInfo. As of October 2026, no Regenerate Company product contains black seed. Nothing here is medical advice.
