Ginger (Zingiber Officinale Roscoe) Elicits Antinociceptive Properties and Potentiates Morphine-Induced Analgesia in the Rat Radiant Heat Tail-Flick Test

Ginger is an herb. The rhizome (underground stem) is used as a spice and also as a medicine. It can be used fresh, dried and powdered, or as a juice or oil. Ginger is commonly used to treat various types of "stomach problems," including motion sickness, morning sickness, colic, upset stomach, gas, diarrhea, nausea and vomiting after surgery, as well as loss of appetite. Other uses include treating upper respiratory tract infections, cough, and bronchitis.

Ginger (Zingiber officinale Roscoe), a well-known spice plant, has been used traditionally in the treatment of a wide variety of ailments. It has been shown that ginger is a calcium channel blocker; however, its influence on morphine analgesic effects has not been elucidated. We examined the effect of ginger root extract on nociceptive threshold and morphine-induced analgesia in male Wistar rats. To determine the effect of ginger on morphine analgesia, ginger extract (200, 400, and 600 mg/kg i.p.) was injected before a subeffective dose of morphine (2.5 mg/kg i.p.). The radiant heat tail-flick test was used to assess the nociceptive threshold before and at different times after drug administration. Our results showed that ginger extract elicited a significant antinociceptive effect. In addition, in groups that received both morphine and ginger, the observed analgesia was higher than that in groups treated with either morphine or ginger extract alone. Thus, the data indicate that ginger extract has a beneficial influence on morphine analgesia and can be an efficacious adjunct for pain management.
