The global publications on Nigella sativa registered 20.87% annual average growth rate and its citation impact averaged to 19.08 citations per paper. The global share of top 10 countries on Nigella sativa ranged from 3.15% to 23.91%, with the largest share (23.91%) from India, followed by Iran (9.58%), Egypt (9.06%), USA (7.15%), etc. 81.31% and 75.74% of the global publication and citation share comes from top 10 countries during 1989-18. The cumulative global share of top 10 countries increased from 70.56% to 82.58% from 1989-03 to 2004-18. Five countries registered relative citation index above the world average of 0.93: Germany (1.86), USA (1.54), Turkey (1.33), Saudi Arabia (1.16) and Egypt (0.94) during 1989-18. Pharmacology, toxicology and pharmaceutics contributed the largest global publications share of 33.97%, followed by agricultural and biological sciences (32.92%), medicine (30.10%), biochemistry, genetics and molecular biology (24.74%), chemistry (12.40%), immunology and microbiology (6.97%), environmental science (5.38%) and veterinary science (3.60%) during 1989-18. 432 organizations and 642 authors participated in global research on Nigella sativa during 1989-18, of which the top 15 most productive research organizations and the authors collectively contributed 23.45% and 6.64% global publication share and 21.82% and 8.04% global citation share respectively during 1989-18. Amongst 3655 journal papers (in 364 journals) in global Nigella sativa research, the top 15 most productive journals together contributed 13.54% global share of total journal publication output during 1989-18. One Hundred Twenty-Six (126) publications were found to be high cited, as they registered citations from 100 to 2971 during 1989-18 and they together received 23426 citations, averaging to 185.92 citations per paper
