Ginger was watery extracted as follows: Fresh rhizomes of
Zingiber officinale
were purchased from a local market. They were shade dried at room temperature and then crushed to powder. 125 g of the powder were macerated in 1000 ml of distilled water for 12 h at room temperature and filtered through a 5 µm filter paper to obtain the final aqueous extract. Accordingly, concentration of the obtained extract was 24 mg/ml and equal to 120 mg/kg. Ginger extract was daily administrated orally, one hour after gabapentin injection, by gavage tube at a dose of 200 mg/kg body weight during the organogenesis phase of gestation. The mentioned dose was found to be the best dose out of four that were tried separately in order to ameliorate the side effects of gabapentin administration.
