Despite the variety of treatments a new study from Cochrane Researchers finds there are currently no reliable, safe and effective methods to relieve this difficult side effect of pregnancy.
The study included 27 clinical trials with more than 4,000 women. It examined the effects of treatments such as acupuncture, vitamin B-6, antihistamines and anti-nausea drugs.
While some of the treatments appeared to have mild benefits, the results were inconsistent and it was difficult to draw firm conclusions.
Ginger is also a popular herbal remedy, but there is also limited evidence it curbed sickness and in some people was shown to cause heartburn.
