Abstract

BACKGROUND:

Due to renowned medicinal properties, Ginger rhizomes (Zingiber officinale Roscoe) used traditionally in the treatment of arthritis, rheumatism, muscular aches, constipation, indigestion, hypertension, dementia, fever, and infectious diseases. As an antiemetic, Ginger is consumed by approximately 80% of pregnant women to treat nausea and vomiting of early pregnancy.

PURPOSE:

The aim of this study is to evaluate the impact of ginger extract on the oestrous cycle and implantation in female mice.

STUDY DESIGN AND METHODS:

Four experimental episodes were identified. One considered the main study of outcomes and lasted 90 days; one lasted 35 days and considered the oestrous cycle; while the third and fourth intended antifertility and abortifacient and continued 20 days for each. Mice dosed Ginger orally at 0, 250, 500, 1000 or 2000  mg/kgbw/day (GNC, GN1, GN2, GN3, GN4, respectively).

RESULTS:

GN3 and GN4 dams showed maternal toxicity. High dose significantly reduced the number of live fetuses and increased fetal death and resorption. Mice treated with 2000  mg/kgbw/day displayed significant decreases in implantation sites. At a dose of 2000  mg/kgbw/day, Ginger prolonged the length of oestrous cycle with a significant decrease in the duration of diestrous-metestrus (luteal) phase, prolonged proestrus-estrus (ovulatory) phase and reduced the number of cycles as well. Therefore, Ginger impairs the normal growth of corpus luteum because of progesterone insufficiency during early pregnancy. The observed-adverse-effect dose set at 2000  mg/kgbw, but no-observed-adverse-effect dose set at 250 and 500  mg/kgbw.

CONCLUSION:

These findings suggest that Ginger can disrupt the oestrous cycle and blastocyst implantation without teratogenesis.
