Effect of onion and ginger consumption on platelet thromboxane production in humans.

The effects of onion and ginger consumption on platelet thromboxane production were examined. Volunteers, all Danish women, consumed either 70 g raw onion or 5 g raw ginger daily for a period of 7 days. Each participant in each (onion or ginger) group served as her own control. TxB2 determination was made in serum obtained after blood clotting. The following are the results. TxB2 (pmol/ml serum): (i) onion group--before consumption 910 +/- 327, after consumption 1005 +/- 713 (Mean +/- SD, N = 5); (ii) ginger consumption 782 +/- 482, after consumption 498 +/- 164 (Mean +/- SD, N = 7).
